Summer Things To Do
In Key West

1. Offshore Snorkeling, Sandbar Charters & Reef Adventures

Summer is the best season for calm seas and crystal-clear underwater visibility along the Florida Reef. Because winter winds have subsided, boat runs out to Western Sambo Ecological Reserve and Sand Key Lighthouse Reef offer pristine snorkeling among sea turtles, nurse sharks, and schools of yellowtail snapper.

For a classic local afternoon, book a private captained sandbar charter out to Snipe Key or the Mud Keys. Wading through waist-deep, transparent water with a cold drink is the quintessential summer ritual, highlighting the exceptional variety of Key West outdoor activities available across the Keys.

2. Celebrate Papa’s Legacy at Hemingway Days

Every July, Key West honors its most famous literary resident with the five-day Hemingway Days celebration. The event centers around Sloppy Joe’s Bar on Duval Street, where dozens of look-alikes compete in the world-famous Hemingway Look-Alike Contest. In addition to the contest, the festival features the Key West Marlin Tournament, literary readings, and a 5K sunset run, filling Old Town with lively camaraderie.

3. Catch the Sunset Celebration at Mallory Square

Sunset along the Key West harbor remains an essential summer experience. Because the sun sets later in summer (between 8:00 PM and 8:15 PM), temperatures cool down just as magicians, unicyclists, and jugglers take the stage on the brick plaza.

Grab a slice of frozen Key lime pie on a stick or a fresh coconut drink from the local food carts while listening to live music along the seawall. Exploring the street performers and waterfront views is one of the top things to do with kids in Key West.

4. Morning Kayak & Paddleboard Mangrove Tours

Kayaking or stand-up paddleboarding through the mangrove channels near Stock Island or Cow Key Marina provides natural canopy shade. Booking an early morning tour (departing by 8:30 AM) ensures glass-flat water and cooler temperatures before the midday sun peaks, giving you an up-close look at manatees, rays, and wading coastal birds.

5. Florida Spiny Lobster Mini-Season

Occurring on the last consecutive Wednesday and Thursday of July, Florida’s 48-hour Spiny Lobster Mini-Season brings recreational divers to island waters. Local charter boats book up months in advance as visitors try their hand at catching spiny lobsters before commercial trapping begins. Many local restaurants will happily cook your fresh catch for dinner.

6. Fourth of July Fireworks and Parade

Key West goes all out for Independence Day, offering a memorable blend of patriotism and island-style fun. The day begins with a parade featuring local organizations, colorful floats and live music. Families and visitors line the streets to enjoy the festive procession, which reflects the unique personality of the island.

As evening approaches, the celebration moves to the waterfront, where the highlight of the day takes place — a spectacular fireworks display over the ocean. Popular viewing spots include Mallory Square^SM and Higgs Beach, both of which offer breathtaking views of the fireworks against the backdrop of the water. For an even more special experience, many visitors choose to watch the display from aboard a boat tour, providing an unparalleled perspective of the colorful show.

Rather than pushing through intense afternoon heat, divide your daily itinerary into three smart phases:

• 8:00 AM – 11:00 AM (Early Outdoor Window): Schedule direct-sun activities early. This is the ideal window for offshore snorkeling charters, sandbar boat excursions, mangrove paddleboarding, or biking around Old Town before temperatures peak.
• 11:30 AM – 4:00 PM (Midday AC Escapes): Retreat indoors during peak heat index hours. Reserve this block for leisurely air-conditioned lunches, boutique shopping, and exploring climate-controlled historic museums.
• 4:30 PM – Sunset (Late Afternoon & Evening Window): Head back outside once the sun drops lower in the sky. Enjoy a late afternoon pool dip, grab a shaded waterfront drink along the docks, and stroll over to Mallory Square for the Sunset Celebration as evening breezes set in.

Climate-Controlled Indoor Attractions

When the midday heat index peaks between 11:30 AM and 4:00 PM, head inside these top air-conditioned sanctuaries:

• The Key West Butterfly & Nature Conservatory (1316 Duval Street): Step into a climate-controlled glass paradise featuring hundreds of live butterflies, colorful exotic birds, and flamingos roaming among tropical plantings.

• Harry S. Truman Little White House (111 Front Street): Walk through Florida’s only presidential museum in cool, air-conditioned comfort while discovering how President Truman conducted nation-shaping executive meetings from Key West.
• Key West Shipwreck Treasure Museum & Custom House Museum: Dive into 19th-century salvage history, touch a real 64-pound silver bullion bar, and explore regional fine art without battling outdoor heat. These indoor galleries also serve as ideal indoor rainy day options when typical 20-minute summer afternoon downpours roll through.

• The Key Lime Pie Kitchen & Bar 1 Bistro (291 Front Street): Tucked inside the air-conditioned Shops at Mallory Square, this is the perfect midday escape from the intense summer heat. Book a quick 30-minute tasting class at the Key Lime Pie Kitchen to sample authentic island pie and learn its history, or pull up a stool at Bar 1 Bistro to cool down with craft cocktails during their interactive Rum Cocktail Adventure class.

• Fort Zachary Taylor Historic State Park: Tour the shaded pre-Civil War brick casemates before relaxing on the beach. Australian pine trees lining the coast offer valuable natural shade, but remember that the shoreline consists of crushed coral—pack water shoes for comfortable swimming.

• The Southernmost Point Buoy: Beat both the heat and the bus tours by arriving at Whitehead and South Streets before 8:30 AM for a quick photo.
• Historic Seaport Boardwalk: Plan your stroll along the Key West Bight after 5:00 PM to watch charter boats dock with the catch of the day while enjoying open-air, shaded harbor-front dining.
