October in Reykjavik is defined by one dramatic shift. Daylight drops from roughly 11 hours at the start of the month to barely 7 by Halloween, and that accelerating darkness opens northern lights season in earnest. The average high reaches 6.4°C (44°F) with lows near 2.2°C (36°F), though wind chill off Faxaflói bay typically makes it feel 3-5°C colder. Rainfall totals 147mm across 17 wet days, often arriving sideways on North Atlantic gusts above 20 m/s (45 mph).
The cultural calendar offers two draws in the first half of the month. Reykjavik International Film Festival (RIFF) typically wraps up its 11-day run in the first week, with screenings at Bíó Paradís and Háskólabíó. Yoko Ono's Imagine Peace Tower on Viðey island begins its annual illumination in early October, visible from the harbor throughout the month. Summer's coach tours have thinned out. You'll share Hallgrímskirkja's observation tower with a handful of visitors instead of the 40-50 per hour typical in July, and accommodation rates in the 101 district sit well below their June-August highs.
To be fair, October is not the easiest month in Reykjavik. The wind off Faxaflói rarely lets up, the lava fields along the Reykjanes peninsula have turned brown after summer's brief green window, and the persistent dampness wears on you after a few days. If aurora viewing matters more to you than sunshine and wildflowers, October works. If outdoor comfort is the priority, June through August averages 11-13°C (52-55°F) with up to 21 hours between sunrise and sunset at the solstice.
Why visit in October
- Northern lights season begins in earnest, with enough nightly darkness by late October to provide consistent aurora-viewing windows whenever skies clear.
- Shoulder-season rates on accommodation and tours sit well below the June-August peak, with wider availability across Vesturbær and the 101 district.
- Summer crowds at the Golden Circle and around the harbor have cleared out. Popular viewpoints feel noticeably less congested on October weekdays.
- The Imagine Peace Tower ceremony on Viðey and the tail end of RIFF give the city a cultural pulse that quieter months like November and January lack.
- Geothermal pools including Laugardalslaug stay at 29-34°C year-round, and October's cold air makes the thermal contrast between heated water and weather far more satisfying than in summer.
Worth knowing
- Rain is persistent throughout October, often driven sideways by wind that makes standard rain gear insufficient without a windproof outer shell.
- Daylight shrinks fast. By the last week, sunrise comes after 9 AM and sunset falls before 6 PM, which limits how far you can venture on day trips to Þingvellir or the Snæfellsnes peninsula.
- Iceland's landscape is at its least photogenic in October. Summer wildflowers are gone, autumn color barely registers at 64°N, and the first snow hasn't yet softened the brown terrain.
- Weather cancellations affect whale-watching operators in the Old Harbour, Snæfellsnes day tours, and Viðey island ferries with enough regularity that schedule flexibility is mandatory.
Best for
Think twice if
October in Reykjavik feels like late autumn colliding with early winter. Humidity averages 83%, which amplifies the cold well beyond what the thermometer suggests. Wind off the North Atlantic dominates more than temperature alone. Weather systems sweep through every 3-4 days, each delivering a band of rain or sleet followed by a brief clearing window. Snow is possible by late October, though it rarely sticks at sea level within the city. You might get a calm, clear afternoon near 8°C (46°F) that feels almost pleasant, then wake to horizontal rain at 1°C (34°F) the next morning.
Seasonal caution
- Coastal wind gusts at Grótta and along the Seltjarnarnes shoreline can exceed gale force, strong enough to knock an adult off balance on the tidal causeway. Check vedur.is wind forecasts before waterfront walks.
- Overnight temperatures can drop below 0°C (32°F) by late October, especially outside the city. Road surfaces on Route 1 north of Borgarfjörður and in mountain passes may ice over without warning.
- Usable daylight narrows sharply toward month's end. Plan any driving outside Reykjavik so you return before sunset, since rural Icelandic roads are unlit and poorly marked after dark.

Best things to do in October
Northern lights viewing from Grótta lighthouse
natureThe Grótta nature reserve at the tip of Seltjarnarnes sits about 4 km west of downtown Reykjavik. Its distance from the city center's light pollution makes it one of the closest reliable aurora-viewing spots. The lighthouse provides a photogenic foreground on clear nights. The causeway to the lighthouse is tidal, so check crossing times before heading out.
October's lengthening nights provide the first consistent aurora-viewing window of the season, and Grótta is accessible on foot or by city bus from Miðborg.Booking tipNo booking needed. Arrive after 10 PM on clear nights and check the Icelandic Met Office aurora forecast at vedur.is daily.
Golden Circle day tour
sightseeingThe 300 km loop through Þingvellir National Park, Geysir geothermal area, and Gullfoss waterfall is Iceland's most popular day trip from Reykjavik. October's reduced crowds mean you'll share viewpoints with 10-20 people instead of the 80-100 typical in July. The tectonic rift at Þingvellir, where the Eurasian and North American plates diverge, takes on a moody quality under low autumn skies.
Summer crowds drop significantly, and the low-angle sun across Þingvellir's lava fields creates the sharpest shadow contrasts of the year. Tour operators still run daily departures through October.Booking tipBook 3-5 days ahead for weekend departures. Weekday tours often have last-minute availability.
Geothermal pool hopping in Reykjavik
wellnessReykjavik operates 7 public geothermal swimming pools. Laugardalslaug in Laugardalur is the largest, with a 50-meter outdoor pool, multiple hot tubs at 38-44°C, and a steam room. Vesturbæjarlaug in Vesturbær is smaller and more of a neighborhood gathering spot. Soaking in hot water while cold rain hits your face is a core part of Icelandic social life.
October's cold air intensifies the thermal contrast with the heated water. The municipal pools are also less crowded now than in summer, when tourists queue at the commercial lagoons instead.Booking tipMunicipal pools require no reservation. Arrive before 8 AM on weekdays to swim with the before-work local crowd.
Whale watching from the Old Harbour
wildlifeHumpback whales, minke whales, and white-beaked dolphins feed in Faxaflói bay through October. Boats depart from the Grandi harbor district, with most operators offering 3-hour tours. Sightings are not guaranteed, and October's sea conditions can produce significant swells. Operators provide warm overalls and rain gear on board.
Late-season feeding before humpback whales begin their southern migration means the animals are still present in the bay, though sighting frequency drops compared to August and September.Booking tipBook with operators offering free rebooking on weather cancellations. Cancellation frequency rises noticeably in October's second half.
Snorkeling Silfra fissure at Þingvellir
adventureSilfra is a fissure in the tectonic rift that runs through Þingvellir National Park, filled with glacial meltwater filtered through lava rock for decades. Visibility exceeds 100 meters year-round. The water sits at a constant 2-4°C (36-39°F), and you'll wear a dry suit for the 30-40 minute route through Silfra Hall, Silfra Cathedral, and Silfra Lagoon.
October's reduced tourism means smaller group sizes, often 6-8 snorkelers instead of the 12-15 typical in July. Underwater visibility is unaffected by surface weather.Booking tipBook at least a week ahead. Only two operators hold the Þingvellir National Park permit for Silfra, which limits daily capacity.
Viðey island and the Imagine Peace Tower
cultureViðey is a small island a 7-minute ferry ride from Skarfabakki harbor in east Reykjavik. The island holds Viðeyjarstofa, one of Iceland's oldest stone buildings, from the 1750s. Yoko Ono's Imagine Peace Tower, a column of light projected skyward from a white stone base inscribed with the words Imagine Peace in 24 languages, stands on the southern shore.
The annual lighting ceremony falls on John Lennon's birthday in early October, and the beam illuminates the harbor nightly for the following two months. The ceremony sometimes draws Ono herself and features live music.Booking tipThe Viðey ferry schedule shrinks to weekends only in mid-October. Check the timetable before planning a weekday visit.
Perlan museum and planetarium
museumPerlan, the glass-domed landmark on Öskjuhlíð hill (opened 1991), houses a nature exhibition with an indoor ice cave, a simulated northern lights planetarium show, and exhibits on Icelandic geology and wildlife. On a clear day, the observation deck offers 360-degree views across Reykjavik and the surrounding mountains.
October's frequent rain makes indoor attractions more valuable. The planetarium's aurora simulation doubles as a backup plan if clouds block the real northern lights during your stay.Booking tipVisit on weekday mornings to avoid the 11 AM to 2 PM tour-group window.
What to eat in October
On menus now
Kjötsúpa
Traditional Icelandic lamb soup made with root vegetables, herbs, and fresh local lamb. October falls right after the réttir, the annual autumn sheep roundup across Iceland's highlands. The meat is at its freshest in the weeks following the roundup, and restaurants across Miðborg serve their own versions of this hearty broth.
Plokkfiskur
Mashed fish stew of cod or haddock mixed with potatoes, onion, and béchamel, served hot. This cold-weather comfort dish appears more prominently on Reykjavik menus from October onward. The version at Café Loki, a few steps from Hallgrímskirkja, has been a reliable standard for years.
Rúgbrauð
Dense, dark Icelandic rye bread traditionally baked underground using geothermal heat over 24 hours. It pairs well with October's fresh lamb or smoked fish, and bakeries in the Laugardalur area stock it daily alongside smjör, Icelandic butter.
What to drink
Brennivín
Iceland's signature caraway-flavored spirit, nicknamed Black Death by locals. The first genuinely cold evenings of the year make October the month when brennivín shifts from novelty to comfort. Kaffibarinn in the 101 district and Skúli Craft Bar on Aðalstræti both serve it neat.
In markets
Harðfiskur
Wind-dried fish, typically haddock or cod, torn into strips and eaten with salted butter. October's cold, dry wind along the coast creates strong curing conditions. Kolaportið flea market is a good source for freshly dried batches when it opens.
Regular events in October
Imagine Peace Tower lighting ceremonyFree
Yoko Ono's light installation on Viðey island projects a beam into the sky as a memorial to John Lennon. The tower was inaugurated in 2007 and the ceremony includes live music and spoken-word readings. A ferry runs from Skarfabakki for the event, and the crowd is a mix of locals and visitors.
October 9 (tower remains lit nightly through December 8)Reykjavik International Film Festival (RIFF)
Iceland's largest film festival screens independent and documentary films from 40+ countries over an 11-day run. Screenings take place at Bíó Paradís on Hverfisgata, Háskólabíó, and smaller venues across the city. The festival has run since 2004 and includes panel discussions with filmmakers.
Late September through early October (typically overlapping the first 3-5 days of October)Fyrsti vetrardagur (First Day of Winter)Free
An old Norse calendar observance marking the official start of the Icelandic winter season. It falls on a Saturday in late October. While not a public holiday with closures, bakeries and cafes in the 101 district sometimes run seasonal specials, and the date is a cultural marker locals still acknowledge.
Saturday between October 19 and 25 (October 24 in 2026)Best places this October
Hallgrímskirkja observation tower
landmarkThe tower of this church, completed in 1986, offers the best panoramic view of Reykjavik's painted-tin rooftops. October's low sun angle throws long shadows across the city grid and catches the harbor water. Clear days are rarer this month, which makes the views from up here more dramatic when they arrive.
MiðborgHarpa Concert Hall
architectureThe glass facade designed by Ólafur Elíasson refracts October's low light into color patterns across the interior. RIFF holds some screenings here during the festival's opening days. The building faces the Old Harbour, and the wind tends to whip around its corners, so approach from the Laugavegur side.
MiðborgLaugardalur valley and botanical garden
parkReykjavik's botanical garden holds around 5,000 plant species from high-latitude regions worldwide. Early October catches the last of the autumn color before the first hard frost strips the remaining leaves. The adjacent pool complex makes a good pairing on a cold day.
LaugardalurGrandi harbor district
neighborhoodThe old fishing-harbor area on the western waterfront has become Reykjavik's museum and gallery cluster. The Marshall House hosts the Living Art Museum and gallery i8. Whales of Iceland, the largest whale exhibition in Europe with 23 life-size models, sits nearby. October foot traffic is light enough to wander between venues without queues.
GrandiHöfði house
historic siteThis 1909 building on the Borgartún waterfront hosted the 1986 summit between Ronald Reagan and Mikhail Gorbachev. The interior is closed to the public, but the exterior and its position overlooking the bay toward Mount Esja are worth the 15-minute walk from downtown, especially when October's clearing skies follow a storm.
MiðborgTjörnin (the city pond)
parkReykjavik's central pond sits between City Hall and the National Gallery. Migrating birds gather here in October before heading south. The surrounding walking paths connect directly to the 101 district's cafe row. On calm mornings, the water reflects the surrounding painted houses and the tower of Fríkirkjan church.
MiðborgNational Museum of Iceland
museumFounded in 1863, the museum covers Iceland's history from settlement-era Viking artifacts through to 20th-century independence. October is a strong month to spend 2-3 hours here, since the weather will likely cancel at least one outdoor plan. The permanent exhibition on the second floor moves chronologically from AD 870 forward.

Insider tips
Kolaportið flea market at Tryggvagata 19 opens only on Saturdays and Sundays, roughly 11 AM to 5 PM. October weekends bring better lopapeysa (Icelandic wool sweater) selection from local sellers than the tourist shops on Laugavegur, at noticeably lower prices.
For northern lights, skip the organized bus tours and head out on your own. The tours go to the same spots, add 90 minutes of logistics, and the guides cannot control the clouds any better than you can with the vedur.is aurora forecast. A taxi or short drive gets you to darker skies faster.
Reykjavik's municipal pools have a strict pre-swim shower protocol. You're expected to shower without a swimsuit and use soap before entering the pool area. Signs in the changing rooms are clear about it. Locals take this seriously, and staff will send you back if you skip the step.
The Bónus supermarket chain, identifiable by the pink pig logo, has a Laugavegur location that is the most affordable grocery option in the 101 district. Reykjavik's restaurant prices are high enough that cooking 1-2 meals a day in your guesthouse kitchen makes a meaningful difference over a 4-5 night stay.
If weather grounds your whale-watching trip, the Whales of Iceland exhibition in Grandi is a genuinely impressive alternative. The blue whale model alone stretches 25 meters across the hall, and the exhibition covers 23 species in total.
Avoid these mistakes
- Packing only for cold without planning for wind and rain. A warm down jacket without a waterproof shell is close to useless in horizontal October rain. The wind, not the temperature, is what makes you miserable in Reykjavik.
- Booking every day with outdoor activities and leaving no buffer. October weather cancels roughly 1 in 3 scheduled tours. Leave at least one open day for rescheduling, or you risk missing the whale watch and the Snæfellsnes trip entirely.
- Expecting to see northern lights on a quick visit. Clear skies are necessary, and October's frequent overcast makes a 2-night weekend stay a gamble. Travelers who allow 4-5 nights have a much stronger chance of catching at least one clear viewing window.
- Driving the Ring Road in October without 4WD and winter-tire experience. Highland F-roads close for the season between mid-September and mid-October. Even Route 1 in the north and east can ice over without warning. Stick to the Golden Circle and south coast if you're not an experienced winter driver.
Practical tips for October
Book accommodation in the 101 Miðborg district or Vesturbær to stay within walking distance of restaurants, museums, and the Old Harbour whale-watching departures. The Flybus between Keflavík International Airport (KEF) and BSÍ terminal runs on a fixed schedule aligned with flight arrivals and is more reliable than a rental car through October crosswinds on the 50-minute Reykjanesbraut stretch. Tipping is not expected in Icelandic restaurants or bars, and most transactions are card-based, though a few Kolaportið vendors prefer cash on weekends. Sunset drops from about 6:45 PM on October 1 to roughly 5:00 PM by October 31, so plan outdoor activities for late morning and early afternoon. Restaurants in the 101 district generally stop seating by 9:30-10 PM, earlier than most European capitals. If wind grounds your outdoor plans, Reykjavik has enough indoor attractions for 2-3 rainy days between the National Museum, Perlan, Harpa, and the Grandi museum cluster.
FAQ
Is October a good time to visit Reykjavik?
It depends on your priorities. October is a fair month for visiting, not the best but far from the worst. The main draw is that northern lights season opens properly, with enough nightly darkness for aurora viewing. You also get shoulder-season pricing and fewer tourists than the summer peak. The trade-offs are real, though. Rain falls persistently, wind is constant, and daylight drops fast. If northern lights and Icelandic culture matter more to you than sunshine and outdoor hiking, October works. If you want reliable weather, June through August is the honest answer.
What is the weather like in Reykjavik in October?
Cold, windy, and persistently damp. Expect highs in the mid-single digits Celsius (low-to-mid 40s Fahrenheit) and lows that approach freezing. Wind is the dominant factor and makes the air feel several degrees colder than the thermometer reads. Rain falls on more than half the month's days, often arriving horizontally. Pack for winter conditions rather than autumn. Snow is possible late in the month but rarely sticks at sea level in the city.
Can you see the northern lights in Reykjavik in October?
Yes, October is one of the first strong months for aurora viewing. The nights are long enough, and solar activity can produce vivid displays. The challenge is cloud cover. You need clear skies, and October's weather patterns produce frequent overcast. Plan for at least 4-5 nights to have a reasonable chance at catching a clear window. Check the Icelandic Met Office aurora forecast daily, and be ready to head outside on short notice when a gap in the clouds opens. Move away from the city center's light pollution for the best views.
Is Reykjavik crowded in October?
Not at all. October sits in the low-season gap between summer's peak tourist period and the December-January holiday spike. Hallgrímskirkja's observation tower, normally packed in July, has minimal wait times. Restaurants in the 101 district that require summer reservations generally seat walk-ins in October. The only concentration of visitors happens around the Imagine Peace Tower ceremony and the tail of RIFF in the first week.
Is it safe to visit Reykjavik alone in October?
Reykjavik is exceptionally safe for solo travelers, with a score of 9.3 out of 10 for solo-traveler safety (see the TTDI Solo-Safety Index). Violent crime is extremely rare, and the city center is compact and walkable. The main solo-travel concern in October is weather-related, not crime-related. Avoid exposed coastal areas like the Grótta causeway in high wind without telling someone your plans, and don't drive outside the city alone in unfamiliar conditions after dark. The smaller October tourist population means more locals around, which tends to make solo dining and socializing easier, not harder.
