December in Rio de Janeiro is defined by one event above all others. Réveillon, the New Year's Eve celebration on Copacabana Beach, draws over 2 million people to a 4-kilometer stretch of sand for fireworks, live music, and the tradition of wearing white. The entire second half of the month bends toward that night, and hotel prices bend with it. Rates in Copacabana and Ipanema can triple during the final week.
The weather is summer at full tilt. Expect daytime highs around 28.7°C (84°F) with lows that rarely dip below 22.4°C (72°F), and humidity sitting at a steady 81%. That combination produces the kind of thick, clinging heat that stays with you even after dark. Afternoon thunderstorms roll in on roughly 16 days of the month, dumping 139mm of rain total, though they tend to pass in 30 to 45 minutes and leave the air smelling like wet concrete and frangipani. Mornings are typically clear, and the city's beaches fill early.
To be fair, December has a split personality. The first two weeks are still reasonably priced and relatively uncrowded. Cariocas are at work, schools haven't broken up yet, and you can get a table at restaurants in Leblon without waiting. After December 20, the city shifts into holiday mode. Flights fill, traffic in the Zona Sul slows to a crawl, and Copacabana becomes standing-room-only. If you time it right, that first half of the month offers summer weather without summer prices.
Why visit in December
- Réveillon on Copacabana Beach is one of the largest free New Year's celebrations on earth, with fireworks visible from Leme to Arpoador and live stages running from 8 PM to dawn.
- Samba school ensaios (open rehearsals) start at venues like Mangueira in Tijuca and Salgueiro in Andaraí on weekend nights, giving you a raw, sweat-soaked preview of Carnival for a fraction of the February price.
- The first two weeks of December still have reasonable hotel rates and thinner crowds, with average highs of 28.7°C (84°F) and long daylight hours that stretch past 7 PM.
- Summer fruit season peaks, with mangoes, cashew fruit, and jackfruit appearing at every corner juice bar and the weekly feira at Rua do Lavradio in Lapa.
- The giant floating Christmas tree on Lagoa Rodrigo de Freitas, the Árvore de Natal da Lagoa, lights up the lagoon nightly and draws families to the waterfront cycling path.
Worth knowing
- Afternoon thunderstorms hit on roughly 16 days, delivering 139mm of rain total. They're short but intense enough to flood low-lying streets in Centro and Praça XV within minutes.
- Hotel prices in Copacabana and Ipanema rise 50-80% in the final 10 days, and many properties enforce 3-night minimums over the New Year's weekend.
- Humidity at 81% makes the 28°C (84°F) daytime heat feel considerably worse, especially on crowded buses and in the Metro between Botafogo and General Osório.
- Petty theft rises sharply in crowded areas during the holiday period. Copacabana Beach on New Year's Eve is a known hotspot for phone snatchings.
Best for
Think twice if
Full summer heat with consistent afternoon storms. Mornings tend to dawn clear and warm, with temperatures climbing quickly by 10 AM. By early afternoon, clouds build over the mountains behind Tijuca, and a sharp thunderstorm typically breaks between 2 PM and 5 PM. The rain is warm and heavy, sometimes accompanied by lightning, but it rarely lasts more than 45 minutes. Evenings cool slightly but remain humid. The ocean temperature sits around 24°C (75°F), warm enough for comfortable swimming. You might get 3 or 4 consecutive dry days, but planning around potential rain is wise for any outdoor activity scheduled after noon.
Seasonal caution
- UV index regularly reaches 11-12 in December, among the highest in the world. Sunburn can happen in under 15 minutes of midday exposure, even on overcast days.
- Flash flooding affects low-lying areas of Centro, Praça Mauá, and parts of the Zona Norte after heavy afternoon storms. Avoid walking through standing water, which can conceal open drains.
- Tropical thunderstorms sometimes produce dangerous lightning. Leave the beach immediately when you hear thunder. The lifeguard service at Copacabana flies a red flag during lightning risk.

Headline events
Réveillon na Praia de Copacabana
December 31, from approximately 8 PM through sunrise on January 1
The world's largest New Year's Eve beach party, drawing over 2 million people to Copacabana's 4-kilometer waterfront. Twelve minutes of fireworks launch from barges offshore, synchronized to music. Multiple live stages feature samba, MPB, and pop acts from 8 PM until sunrise. The tradition of wearing white and throwing flowers into the sea comes from Candomblé offerings to Iemanjá, the goddess of the ocean.
Best things to do in December
Réveillon on Copacabana Beach
festivalArrive by early evening to claim sand space near one of the 8+ live stages set up along the 4-kilometer stretch from Leme to Copacabana Fort. The fireworks launch from barges at midnight, and the crowd of 2 million people dressed in white throws flowers into the Atlantic for Iemanjá. The energy is thick, the bass rattles your ribs, and the smell of gunpowder mixes with salt air.
Réveillon falls on December 31 and is the single event that defines Rio's December calendar.Booking tipNo ticket needed. Arrive before 8 PM for any hope of a spot near the stages. The Metro runs extended hours on New Year's Eve, and the Siqueira Campos and Cardeal Arcoverde stations are the closest.
Samba school ensaios at Mangueira or Salgueiro
musicThe big samba schools open their quadras (rehearsal halls) to the public on weekend nights starting in December. Mangueira's quadra sits in Tijuca, Salgueiro's in Andaraí. The sound inside is deafening. Hundreds of percussionists in the bateria section play at full volume while dancers rehearse choreography for the February parade. The concrete floors vibrate, and the heat inside the open-air halls is intense.
December marks the start of pre-Carnival ensaio season, with smaller crowds and a more intimate atmosphere than the packed January rehearsals.Booking tipCheck each school's social media pages for the weekly ensaio schedule. Arrive by 10 PM, as the bateria typically starts around 11 PM. Take a taxi or rideshare back, as the neighborhoods are not well-served by Metro late at night.
Sunrise hike to Pedra Bonita
outdoorThe trail to Pedra Bonita starts in the Tijuca National Park and takes about 40 minutes to reach the summit. The payoff is a 360-degree view of the Zona Sul coastline, the Lagoa, and Corcovado. December's early sunrises (around 5:10 AM) mean you can finish before the heat sets in. The air at the top still carries the coolness of the night, and the city below is quiet.
December's long daylight hours and early sunrise make it possible to hike before the afternoon heat and storms arrive. The trail is dry and firm in the morning.Booking tipStart by 5 AM to reach the summit for sunrise. No booking required, but bring a headlamp for the first section of trail. The hang-gliding launch ramp at the top is a landmark you can't miss.
Swimming at Prainha
beachPrainha is a 700-meter crescent of sand tucked behind a headland in the Zona Oeste, about 40 minutes by car from Copacabana. The water is cleaner than the Zona Sul beaches, the waves are consistent for bodyboarding, and the surrounding mata atlântica forest gives the whole cove a green, enclosed feeling. A handful of rustic kiosks sell grilled fish and cold beer.
December's warm ocean temperatures (around 24°C) and long days make Prainha's exposed beach comfortable all day. The morning hours before the afternoon rain are ideal.Booking tipNo public transit reaches Prainha reliably. Drive or take a rideshare. Arrive before 10 AM on weekends, as the small parking area fills quickly.
Cycling the Lagoa Rodrigo de Freitas loop
outdoorThe 7.5-kilometer paved path around Lagoa Rodrigo de Freitas is flat and shaded in patches by palm trees. December evenings bring the floating Christmas tree's light show reflected on the water, and families crowd the kiosks along the eastern shore. Rental bikes are available at several stations around the loop. The smell of grilling meat from the kiosks drifts across the path.
The Árvore de Natal da Lagoa (floating Christmas tree) is lit nightly through early January, making the December evening loop a seasonal experience you can't replicate in other months.Booking tipRio's Bike Itaú bike-share stations ring the lagoon. The eastern shore near Parque dos Patins gets the best tree views.
Day trip to Ilha Grande
day_tripThe island sits about 3 hours south of Rio by bus and boat (via Conceição de Jacarei or Mangaratiba). No cars are allowed. The beaches at Lopes Mendes and Praia do Aventureiro have white sand and clear water. Trails connect over 100 beaches around the island. The forest canopy buzzes with cicadas, and howler monkeys are loud at dawn.
December's warm water and extended daylight make the boat crossing smoother and the beach time longer. Weekdays in early December still have relatively thin crowds before the holiday rush.Booking tipBook boat tickets a few days in advance for travel after December 20. Early December weekdays tend to have walk-up availability. The crossing from Conceição de Jacarei takes about 90 minutes.
Exploring the Selarón Steps in Santa Teresa
cultureThe 215-step staircase on Rua Manuel Carneiro, covered in over 2,000 tiles from 60+ countries, was the life's work of Chilean artist Jorge Selarón, who began tiling in 1990. The steps connect Lapa to Santa Teresa. December's morning light hits the tiles at a low angle, and the reds, yellows, and greens pop against the whitewashed buildings. Vendors sell coconut water at the base.
Morning visits in December beat the afternoon rain and catch the best light on the tiles. The adjacent Santa Teresa neighborhood is livelier in summer, with galleries and cafes open later.Booking tipVisit before 10 AM to avoid tour groups. The steps are open 24 hours, but the surrounding area is best visited in daylight.
Evening at Pedra do Sal
nightlifeThis small square in the Saúde neighborhood, built around a historic rock face, is considered the birthplace of samba in Rio. On Monday and Friday nights, live roda de samba sessions spill out of the bars and onto the cobblestones. The crowd is mostly local. The percussion bounces off the old stone buildings, and the air smells like fried pastéis and cold Brahma beer.
December's warm evenings make the outdoor roda de samba sessions at Pedra do Sal particularly comfortable. The pre-holiday energy adds extra musicians and dancers to the regular crowd.Booking tipArrive by 8 PM on Monday or Friday to get a seat at one of the small bars. No cover charge for the outdoor sessions. Take the VLT light rail to the Parada dos Navios stop, a 5-minute walk away.
What to eat in December
In season: fruit
Manga rosa
Brazilian pink mango hits peak season in December. The flesh is softer and sweeter than the common Tommy Atkins variety, with a floral, almost perfumed flavor. Juice bars across Copacabana and Ipanema blend it fresh, and you'll find it sliced at every beach vendor's cart along Posto 9.
Caju (cashew fruit)
The whole cashew fruit appears at feiras and street stands in December, bright yellow or red, with the nut still attached. The fruit itself is tart and astringent, better as fresh-pressed suco de caju than eaten raw. Stalls at Feira de São Cristóvão sell it by the bag.
On menus now
Açaí na tigela
Açaí bowls are year-round in Rio, but December's heat makes them a near-daily habit. The frozen purple pulp comes topped with granola, sliced banana, and a drizzle of honey. Vendors in Ipanema and Leblon serve them thick enough that the spoon stands up on its own. The cold, earthy sweetness cuts through the midday humidity.
Street food peaks
Biscoito Globo
These puffy, airy tapioca-starch biscuits are Rio's signature beach snack, sold by vendors walking the sand at Copacabana and Ipanema since 1953. They come in sweet and salty versions, both with a light crunch that dissolves on your tongue. December's beach crowds keep the Globo vendors busy from dawn to dusk.
What to drink
Caipirinha de frutas
Summer fruit season means caipirinha variations multiply. Bars in Lapa and Botafogo mix cachaça with fresh maracujá (passion fruit), caju, or manga rosa instead of the standard lime. The Beco do Rato bar district in Lapa tends to be where bartenders get most creative with seasonal combinations.
Regular events in December
Árvore de Natal da Lagoa (Lagoa Christmas Tree)Free
A large floating Christmas tree structure on Lagoa Rodrigo de Freitas, lit nightly with a synchronized light and music show. The tradition dates back to 1996, and the tree has reached heights of over 80 meters in past years. Families gather along the waterfront path, and food vendors line the eastern shore.
Early December through early January, nightly from around 8 PMFeira de São Cristóvão
The permanent northeastern Brazilian culture fair in the São Cristóvão pavilion runs all month, but December weekends bring extended hours and special forró dance nights. Over 700 stalls sell regional food from the Nordeste. The baião de dois (rice and beans with dried meat and cheese) is heavy and salty, and the tapioca crepes are filled with coalho cheese.
Weekends, Friday evening through Sunday nightChristmas Mass at Candelária ChurchFree
The Igreja da Candelária in Centro, built between 1775 and 1898, holds a midnight Christmas Mass on December 24 that draws thousands. The baroque interior, with its painted dome and gilded altars, is striking under candlelight. Even non-religious visitors attend for the architecture and the choir. Arrive at least an hour early for a seat.
December 24, midnightSummer concert series at Parque Lage
The Escola de Artes Visuais at Parque Lage, housed in a 1920s mansion at the foot of Corcovado, hosts outdoor music events on select December evenings. The courtyard pool reflects the mansion's arches, and the surrounding rainforest canopy frames the stage. Acts lean toward MPB and experimental Brazilian music.
Select weekends in December, typically Saturday eveningsBest places this December
Copacabana Beach
beachThe 4-kilometer Atlantic-facing beach is Rio's most famous stretch of sand, and December turns it into the city's living room. Morning joggers share the mosaic-patterned calçadão sidewalk with juice vendors setting up carts. By 9 AM the beach chairs are out, and the postos (numbered lifeguard stations) help you orient. Posto 6, near the Copacabana Fort, tends to be less packed than the middle sections.
CopacabanaSugarloaf Mountain (Pão de Açúcar)
landmarkThe cable car to Sugarloaf departs from Praia Vermelha in Urca, stopping at Morro da Urca before reaching the 396-meter summit. December's clear mornings offer views down the coast to Niterói and across Guanabara Bay. The second cable car segment sways noticeably in wind. Time your visit for before noon to avoid both the afternoon storm clouds and the longest queues.
UrcaCristo Redentor (Christ the Redeemer)
landmarkThe 30-meter Art Deco statue sits at 710 meters atop Corcovado. The cog railway from Cosme Velho takes 20 minutes through the Tijuca rainforest, and the train cars smell like diesel and damp vegetation. December mornings before 10 AM tend to have the clearest views. By afternoon, clouds frequently wrap the summit, and you'll see nothing but white mist.
Santa Teresa / Cosme VelhoJardim Botânico
parkRio's botanical garden covers 54 hectares at the base of the Corcovado massif. The Avenue of Royal Palms, planted in 1842, is the most photographed feature. December brings the pau-brasil trees and heliconia into bloom, and the bromeliads along the shaded paths are at their most vivid. The air inside the garden is noticeably cooler than the surrounding streets, and the sound drops to birdsong and water.
Jardim BotânicoMuseu de Arte do Rio (MAR)
museumThe museum sits in a pair of connected buildings at Praça Mauá, near the revitalized Porto Maravilha waterfront. The permanent collection traces Rio's visual history from colonial maps to contemporary installations. The rooftop terrace gives a wide-angle view of Guanabara Bay. December is a good month to visit because the air-conditioned galleries offer relief from the midday heat.
CentroParque Nacional da Tijuca
natureThe world's largest urban rainforest covers over 3,900 hectares within Rio's city limits. December trails are lush and loud with birdsong and insect noise. The Cascatinha Taunay waterfall, a 30-meter cascade about 15 minutes' walk from the Alto da Boa Vista entrance, runs strong after the afternoon rains. The canopy keeps temperatures a few degrees cooler than the beaches below.
TijucaSanta Teresa neighborhood
neighborhoodThe hillside neighborhood above Lapa is reached by the yellow Bondinho tram, which runs along Rua Almirante Alexandrino. The streets are steep and lined with 19th-century mansions, many converted into galleries, bars, and guesthouses. The Largo do Guimarães square has a cluster of restaurants with outdoor seating. December evenings in Santa Teresa are warm enough to eat outside until late.
Santa TeresaArpoador Rock
viewpointThe rocky point between Ipanema and Copacabana beaches draws crowds every evening for sunset. In December, the sun sets around 7:30 PM, and the crowd breaks into applause as it dips behind the Dois Irmãos peaks. The flat rock surface holds maybe 200 people. Arrive 30 minutes before sunset for a spot. The warm wind carries salt spray, and surfers ride the break directly below.

Insider tips
The Metro operates extended hours on New Year's Eve, typically running until 2 AM or later. The Siqueira Campos station (Line 1) is the closest to the main Réveillon action on Copacabana, but Cardeal Arcoverde in Ipanema is less jammed at exit time.
For samba school ensaios, Mangueira's quadra in Tijuca tends to be friendlier to tourists than some of the larger schools. The vibe is more neighborhood party than performance. Dress light, because the concrete halls trap heat.
Posto 6 at the far eastern end of Copacabana Beach, near the Forte de Copacabana, is consistently less crowded than the mid-beach sections around Postos 3-4. The fort itself opens early for a military-run cafe with views down the beach.
Arpoador Rock fills for sunset every evening in December. The crowd genuinely applauds when the sun goes down. Arrive 30 minutes early and bring something to sit on, because the rock surface holds residual heat from the day.
If you're in Rio for Christmas Eve, the midnight mass at Candelária Church in Centro is a striking experience even for non-religious visitors. The 1898 baroque interior is lit by candles, and the acoustics amplify the choir into something physical. Arrive by 11 PM for a seat.
Early December weekdays are the best window for visiting Cristo Redentor without long queues. By the third week, school holidays and domestic tourists from São Paulo and Minas Gerais fill the cog railway. Book the first departure of the day for the clearest summit views.
Avoid these mistakes
- Booking a hotel for only the last 3 days of December. Most Copacabana and Ipanema hotels enforce 3 to 5-night minimums over the New Year's period, and availability disappears months in advance. If Réveillon is your goal, book by September.
- Planning outdoor activities for the afternoon. December's thunderstorms consistently arrive between 2 PM and 5 PM. Hikes to Corcovado, Sugarloaf visits, and beach time are all better scheduled before noon.
- Carrying a phone in your back pocket on Copacabana Beach. Petty theft peaks during the holiday crowds, and phone-snatching is the most common method. Use a crossbody bag or leave valuables at your hotel.
- Assuming the whole month is equally expensive. The first two weeks of December are 10-20% above average, which is manageable. The price spike hits after December 18. Travelers on a budget should plan their trip for early December and fly out before the 20th.
- Skipping sunscreen on overcast days. The UV index in December regularly reaches 11-12, and cloud cover in Rio doesn't block UV effectively. Burns happen in 15 minutes of midday exposure even when the sky looks gray.
Practical tips for December
Book Réveillon-period hotels by September or October for the best selection in Copacabana and Ipanema. Early December (before the 18th) offers substantially lower rates and thinner crowds while still delivering full summer weather. The Metro is the most reliable transport in the Zona Sul, running from Ipanema (General Osório) through Copacabana, Botafogo, and into Centro. Taxis and rideshare apps (99 and Uber both operate in Rio) are widely available, but surge pricing applies on New Year's Eve and during heavy rain. Carry cash in smaller denominations for beach vendors and small bars, as many do not accept cards. Portuguese helps significantly outside the main tourist strip. Even basic phrases ("quanto custa," "por favor," "obrigado/obrigada") change the interaction. The city's emergency number is 190 (military police) or 192 (ambulance). For weather, check INMET (Brazil's meteorological service) for storm warnings, as the afternoon systems can intensify rapidly.
FAQ
Is December a good time to visit Rio de Janeiro?
December is a good but not ideal month. The weather is full summer, with highs around 28.7°C and warm ocean water at 24°C. Réveillon on New Year's Eve is a once-in-a-lifetime event. That said, the combination of high humidity (81%), daily afternoon storms, peak holiday pricing in the second half, and large crowds makes it a month that rewards careful timing. Early December, before the 18th, offers the best balance of summer weather and manageable prices.
How far in advance should I book hotels for New Year's Eve in Rio?
For Copacabana and Ipanema beachfront properties, 3-4 months in advance is the minimum. Many hotels enforce 3 to 5-night minimums for the Réveillon period and sell out by October. Neighborhoods further from the beach, like Botafogo, Flamengo, or Santa Teresa, tend to have availability longer, but still book earlier than you might expect for a South American city.
Does it rain every day in Rio in December?
Not every day, but close. Rain falls on roughly 16 of 31 days, totaling about 139mm for the month. The pattern is consistent. Mornings are typically clear and hot. Clouds build by early afternoon over the Tijuca mountains, and a thunderstorm breaks between 2 PM and 5 PM. It passes in 30-45 minutes. You might get 3 or 4 dry days in a row, but planning morning activities and keeping afternoons flexible is the safe approach.
What should I wear to Réveillon on Copacabana Beach?
White. The tradition of wearing all white on New Year's Eve comes from Candomblé religious practice and is followed by the vast majority of the 2 million+ attendees. You won't be turned away in other colors, but you'll stand out. Wear comfortable sandals or shoes you don't mind getting sandy, and dress for warm, humid conditions. Temperatures at midnight typically sit around 25°C (77°F).
Is it safe to go to Copacabana Beach on New Year's Eve?
The beach itself is heavily policed during Réveillon, with thousands of military police and municipal guards deployed along the 4-kilometer stretch. That said, with 2 million people packed onto the sand, petty theft is a real risk. Leave valuables at your hotel, carry only the cash you need, and keep your phone in a front-facing bag. Avoid dark side streets off the main beachfront after midnight. Stick with the crowd and you'll likely be fine, but stay aware.
Can I visit samba school rehearsals in December?
Yes. Several of Rio's top samba schools, including Mangueira (Tijuca) and Salgueiro (Andaraí), open their quadras for public ensaios on weekend nights starting in December. The atmosphere is less polished and more raw than the February Carnival parade. Entry fees are modest compared to Carnival tickets, and the experience of hearing a full bateria (percussion section) at close range in a concrete hall is physically intense. Check each school's social media for the current schedule, as dates shift week to week.
