Summer in the Florida Keys: What to Know Before You Go
There’s nothing quite like summer in the Florida Keys. Warm breezes, turquoise waters, and endless sunshine create the perfect setting for fishing trips, boating adventures, snorkeling excursions, and relaxed beach days. Whether you're planning your first trip or you're a seasoned visitor, here’s everything you need to know about visiting the Keys during the summer months — including tips on weather, travel costs, and timing your getaway just right.
What is the Best Month to Visit the Florida Keys?
While the Florida Keys are a year-round destination, many travelers consider May and June among the best months to visit. During these early summer months, the weather is warm but not oppressively hot, and crowds tend to be lighter than during the winter high season. You can expect sunny skies, comfortable sea temperatures for snorkeling and diving, and plenty of opportunities to enjoy the islands without the peak season rush.
If you prefer slightly cooler weather, March and April are also very popular months — but they tend to come with higher hotel rates and more visitors.
How Hot Does It Get in the Florida Keys in the Summer?
During summer in the Florida Keys, daytime highs typically range from 85°F to 90°F (29°C to 32°C). Thanks to constant ocean breezes, the heat feels more comfortable compared to inland Florida.
Humidity is part of the summer climate, so be prepared for warm, tropical conditions. Light clothing, sun protection, and plenty of water will keep you comfortable while you enjoy activities like boating, fishing, snorkeling, or simply relaxing at the beach.
Tip: Early mornings and evenings are the most pleasant times to be outside for active adventures like kayaking, paddleboarding, or sightseeing.
What is the Cheapest Month to Go to the Florida Keys?
September is often the cheapest month to visit the Florida Keys. As part of the off-season, September brings lower hotel rates, fewer crowds, and some great deals on accommodations and tours. However, it’s also part of the Atlantic hurricane season, which runs from June through November, so flexible travel plans and travel insurance are recommended.
Other affordable months:
- Late August
- Early October
- Early December (before the holiday rush)
Booking during these shoulder periods allows you to enjoy the Keys' beauty at a fraction of the high-season cost.
What is the Hottest Month in the Florida Keys?
August is generally the hottest month in the Florida Keys, with average daytime temperatures often hitting 90°F (32°C) or slightly higher. Warm ocean temperatures also mean the water is perfect for swimming, snorkeling, and diving without a wetsuit.
Despite the heat, August remains a fantastic time to enjoy the water-based lifestyle the Keys are known for — from sandbar trips to sunset cruises.
Things to Do in the Summer in the Florida Keys
Even with higher temperatures, summer in the Keys offers plenty of unforgettable activities for visitors:
