July in Key West is about the heat. Step off the plane at Key West International Airport and the humidity hits your skin immediately, warm and close. Daytime highs average 29.9°C (86°F) with 76% humidity, and the feels-like temperature climbs past 34°C (93°F) by late morning. This is the island's deep low season. Duval Street feels noticeably quieter than the December through March peak, and accommodation rates sit well below their winter highs.
Afternoon thunderstorms arrive on roughly 16 days this month, sometimes with enough lightning to clear Smathers Beach for an hour. The Atlantic hurricane season is well underway, and while direct July landfalls on the Florida Keys remain statistically uncommon, tropical weather systems can disrupt flights and ferry schedules with limited lead time. A flexible booking policy helps.
Hemingway Days fills Old Town during the third week of the month. The festival brings the famous Look-Alike Contest to Sloppy Joe's Bar on Greene Street and draws a solid week of national media attention. The Florida Keys spiny lobster sport season opens in the final days of July, and divers from across South Florida converge on the reef. By evening, after the afternoon storms pass, the air smells like wet limestone and salt off the harbor. The sky turns pink over Sunset Key after 8 PM, among the latest sunsets of the year.
Why visit in July
- Accommodation rates typically drop 30 to 50% below the December through March peak, with last-minute availability at most guesthouses and hotels
- Hemingway Days during the third week of July brings 5 days of literary events, the iconic Look-Alike Contest, and national media attention to Old Town
- Water temperatures peak in July, making this one of the strongest months for snorkeling and diving along the reef
- The spiny lobster sport season opens in late July, and restaurants across the island feature fresh-caught lobster within hours of the first dives
- Summer sunsets begin after 8 PM, giving the nightly Mallory Square celebration an extended, unhurried window
Worth knowing
- Heat index regularly exceeds 38°C (100°F) by early afternoon, making extended outdoor walking between 11 AM and 3 PM genuinely uncomfortable
- Afternoon thunderstorms hit roughly half the days in July, sometimes with intense lightning that closes beaches and outdoor attractions for an hour or more
- Peak Atlantic hurricane season runs June through November, and while July direct hits are rare, tropical weather systems can ground flights with limited warning
- Several restaurants, galleries, and shops reduce hours or close entirely for the summer low season
Best for
Think twice if
July sits in the middle of Key West's wet season, though the island receives less rainfall this month than in June, August, or September. The temperature range is narrow, with barely 2°C separating the daily high from the overnight low, so nights feel nearly as warm as afternoons. Mornings tend to start clear and calm, with cumulus clouds building after noon and storms typically arriving between 2 and 3 PM. The rain is heavy but brief, usually clearing within 30 to 45 minutes. Wind is light, generally from the southeast at 10 to 15 km/h (6 to 9 mph). Ocean water temperature sits near 29°C (84°F), often warmer than the air after sunset.
Seasonal caution
- Atlantic hurricane season is active from June 1 through November 30. Monitor NOAA's National Hurricane Center forecasts weekly and carry travel insurance with trip-interruption coverage.
- UV index reaches 10 to 11 in July, among the highest in the continental United States. Unprotected skin can burn in under 15 minutes. Reapply sunscreen every 60 to 90 minutes, especially near water.
- Heat index can exceed 38°C (100°F) in early afternoon. Limit outdoor activity between 11 AM and 3 PM, stay hydrated, and recognize the signs of heat exhaustion.

Headline events
Hemingway Days Festival
Mid-to-late July, approximately July 15-21, centered around Ernest Hemingway's July 21 birthday
Key West's biggest annual festival brings hundreds of bearded impersonators for the Look-Alike Contest, a playful Running of the Bulls along Duval Street, and the Marlin Tournament on offshore waters. The celebration marks the anniversary of Ernest Hemingway's July 21 birthday and draws national media coverage for the better part of a week.
Best things to do in July
Morning reef snorkeling
water sportsThe reef system off Key West's south shore sits within the Florida Keys National Marine Sanctuary and hosts elkhorn coral, parrotfish, and nurse sharks. Morning trips on calm water offer the strongest visibility before afternoon clouds build.
Water temperatures peak in July, warm enough that a wetsuit is unnecessary. Morning conditions on the reef tend to be the calmest and clearest of the year.Booking tipReserve morning departure slots 3 to 5 days ahead. Afternoon trips face a high cancellation rate from weather.
Hemingway Days writing workshops and walking tours
cultureThe festival's hands-on events include fiction-writing workshops at the Ernest Hemingway House on Whitehead Street, a literary walking tour of Old Town tracing the author's daily route, and short-story competitions judged by published authors.
These workshops and tours run only during the third week of July. Outside the festival, the literary walking tour format is not offered.Booking tipRegister for workshops through the Hemingway Home website before arriving. Walking tours tend to fill 1 to 2 weeks ahead.
Sunset catamaran sail from the Historic Seaport
water sportsCharter catamarans and schooners depart from the Historic Seaport at Key West Bight for 2-hour sunset cruises. Most include drinks. The harbor opens onto the Gulf of Mexico with an unobstructed western horizon.
July sunsets begin after 8 PM, the latest of the year, giving evening sails the longest golden-hour window of any month.Booking tipEven in low season, popular boats fill 3 to 5 days ahead for sunset departures. Weeknight sails are easier to book.
Spiny lobster sport season diving
water sportsFlorida's annual 2-day mini-season opens in late July. Divers and snorkelers hunt spiny lobster on the shallow reef flats south of the island. A Florida recreational saltwater fishing license and a separate lobster stamp are required, both available online through the Florida Fish and Wildlife Conservation Commission.
The sport season occurs on only 2 days each year, the sole window to harvest lobster before the regular August season opens.Booking tipCharter dive boats for mini-season sell out weeks in advance. Purchase your license and lobster stamp online before arriving.
Early morning cycling through Old Town and Bahama Village
outdoorRent a bicycle and ride the quiet streets of Old Town and Bahama Village before 9 AM. In summer, you'll pass the Hemingway cats resting on Whitehead Street porches, see fishing boats at the bight, and have the lanes largely to yourself.
July's low season means fewer pedestrians and almost no tour groups before 9 AM. The morning air sits at its most comfortable before the heat builds after 10.Swimming at Fort Zachary Taylor Historic State Park
outdoorThe park has the best natural beach on the island, with a rocky shoreline that drops into clear water populated by tropical fish. The Civil War-era fort, built in 1845, sits above the beach and is open for self-guided tours.
The bathtub-warm water and thinner summer crowds make this a more relaxed experience than during the packed winter months. Shaded spots under the trees are available without arriving at park opening.Bioluminescent kayak tour in the backcountry
water sportsNight kayaking tours paddle through mangrove channels in the backcountry north of Key West. When you dip a paddle into the dark water, trails of blue-green light appear from bioluminescent dinoflagellates.
Warm summer water temperatures favor higher concentrations of bioluminescent plankton. July tends to produce stronger displays than cooler months.Booking tipBook for a night with minimal moonlight. The effect is strongest during new-moon weeks. Check a lunar calendar before choosing your date.
What to eat in July
In season: fruit
Florida mango
South Florida varieties like Valencia Pride and Nam Doc Mai reach peak ripeness in July. You'll find them at roadside fruit stands along the Overseas Highway on the drive in.
On menus now
Yellowtail snapper
Summer is peak catch season for yellowtail in the Keys. Charter boats bring it in daily, and waterfront restaurants along the Historic Seaport serve it blackened or grilled.
Street food peaks
Key lime pie on a stick
The classic Key West dessert dipped in dark chocolate and frozen on a stick. Several bakeries in Old Town sell their own version, and the frozen format is the more satisfying choice in July.
What to drink
Rum runner
The frozen cocktail traces its roots to the Keys, blending banana, blackberry liqueur, and dark rum over ice. In July heat, the frozen format moves from tourist novelty to sensible decision.
In markets
Spiny lobster
The sport season in late July marks the first fresh-caught lobster of the year. Restaurants across Key West feature it grilled, broiled, or in ceviche almost immediately.
Regular events in July
Fourth of July CelebrationFree

Last consecutive Wednesday and Thursday before August 1 (July 29-30 in 2026)Best places this July
Fort Zachary Taylor Historic State Park
parkIn July, the shaded picnic areas under Australian pines become the most comfortable lunch spot on the island. The park's south-facing beach catches steady offshore breezes that soften the afternoon heat.
Truman AnnexMallory Square
plazaThe nightly Sunset Celebration draws street performers, food vendors, and visitors to the waterfront plaza. July's late sunset, the latest of the year, gives the whole event an extended, unhurried feel that winter visits lack.
Old TownKey West Butterfly and Nature Conservatory
attractionA climate-controlled glass conservatory housing over 50 butterfly species, flamingos, and tropical birds. In July, the air-conditioned interior is a genuine midday refuge, and summer foot traffic is lighter than the winter peak.
Old TownBahama Village
neighborhoodThe residential neighborhood between Whitehead Street and Fort Street keeps a quieter, locals-first pace year-round. In July's low season, it becomes one of the most relaxed parts of the island. Restaurants along Petronia Street run summer menus.
Bahama VillageHiggs Beach and the African Cemetery memorial
beachA south-facing public beach with morning breezes and a memorial marking the resting place of nearly 300 Africans who died after rescue from slave ships in the 1860s. The beach draws fewer people than Smathers and has a calmer feel before noon.
Casa MarinaKey West Aquarium
museumOne of the first open-air aquariums in the United States, opened in 1934. The original design catches harbor breezes. Guided tours include hands-on encounters with nurse sharks and sea turtles. Summer attendance is low enough that you rarely wait for a feeding session.

Insider tips
The sunset at Mallory Square starts later in July than any other month, after 8 PM. Schedule dinner at a Bahama Village restaurant for 6 PM and you'll still have time to walk over for the full show.
Several Old Town restaurants run summer-only locals' menus with reduced prices that are not posted online. Look for chalkboard specials outside or ask your server about a summer menu.
The best snorkeling at Fort Zachary Taylor is from the south end of the beach. Swim out about 20 meters (65 feet) from the point and you'll be over the reef line with parrotfish and sergeant majors without paying for a boat.
Morning hours between 6 and 9 AM are when Key West feels most livable in July. The streets are empty, the light is soft for photography, and the temperature has not hit its stride yet. Plan walking and outdoor time for this window.
Key West's tap water travels 130 miles (209 km) from the mainland through the Florida Keys Aqueduct Authority pipeline. It is safe to drink but carries a mineral aftertaste from the treatment. Most locals filter it.
Avoid these mistakes
- Scheduling a walking tour or outdoor sightseeing for midday. The heat between 11 AM and 3 PM in July is not mild discomfort, it borders on dangerous for anyone who is not acclimated. Book early morning or late afternoon time slots.
- Booking an early sunset cruise. July sunsets in Key West do not start until after 8 PM. A 6 PM departure returns you to the dock before the sky changes color. Choose a 7 PM departure at the earliest.
- Leaving hurricane-season travel without cancellation coverage. Tropical storms can form in the Atlantic with 3 to 5 days of lead time and ground all flights from Key West International Airport. Refundable bookings or travel insurance are worth the small premium.
- Assuming all restaurants and shops keep their winter hours. Several establishments along Duval Street reduce to 4 or 5 days per week in summer, and a few close entirely from June through September.
Practical tips for July
Most attractions in Old Town keep reduced summer hours in July, typically closing an hour earlier than posted winter schedules. Confirm hours before visiting the Harry S. Truman Little White House or the Mel Fisher Maritime Heritage Museum. Book all water-based excursions for morning departures before 9 AM, since afternoon weather cancellations run 40 to 50% this month. The free Duval Loop shuttle runs air-conditioned buses along the main corridor every 15 to 20 minutes, a genuine relief in the midday heat. If arriving by car, parking in Old Town is limited and metered. The island is roughly 6.4 km (4 miles) long and 1.6 km (1 mile) wide, easily covered by bicycle outside the hottest hours. Several restaurants shift to summer schedules or close entirely from June through September. Call ahead before walking to dinner.
FAQ
Is July a good time to visit Key West?
July rates as fair. The heat and humidity are serious, afternoon storms are nearly daily, and this is Atlantic hurricane season. But accommodation rates reach their annual low, crowds thin to a fraction of winter levels, and Hemingway Days during the third week brings a genuine cultural reason to visit. If you handle subtropical heat well and want Key West without the tourist crush, July works. If you need guaranteed clear skies or cool evenings, wait for January through March.
What is the weather like in Key West in July?
Hot and humid with daily afternoon thunderstorms. Highs sit around 30°C (86°F) and overnight lows stay near 28°C (82°F), so there is no cool relief after dark. Humidity sits at 76%. Rain falls on roughly half the days in the month, but the storms typically blow through in 30 to 45 minutes. Mornings tend to be bright and calm before the clouds build after noon.
Is Key West crowded in July?
No. July is one of the quietest months on the island. The winter peak season runs from December through March, when cruise ships and visitors from the northeast fill Old Town daily. By July, that traffic is gone. You will find shorter lines at the Southernmost Point buoy, easier restaurant reservations, and a noticeably calmer pace along Duval Street.
Is it safe to visit Key West during hurricane season in July?
July falls early in the Atlantic hurricane season, which runs June 1 through November 30. Historically, major hurricane landfalls on the Florida Keys in July are less common than in August through October. That said, tropical storms and depressions can form with limited lead time and disrupt flights from Key West International Airport for 2 to 3 days. Book refundable accommodation and carry travel insurance. Monitor NOAA's National Hurricane Center forecasts in the weeks before your trip.
What is the spiny lobster mini-season in the Florida Keys?
Florida opens a 2-day recreational sport season for spiny lobster on the last consecutive Wednesday and Thursday before August 1 each year. In 2026, those dates fall on July 29 and 30. You need a valid Florida recreational saltwater fishing license and a separate lobster stamp, both available online. The mini-season draws thousands of divers to the Keys, and Key West restaurants feature fresh lobster specials through the following weekend.
