The sweet spot: May and June
After spring break crowds disperse and before school vacation season begins, Key West feels more local, more walkable and more personal. Restaurants are easier to book, beaches feel less crowded, and it’s easier to slip into the everyday rhythm of island life — morning bike rides, afternoon swims, and sunset strolls. Weather-wise, early summer delivers exactly what visitors dream of. Expect daytime temperatures in the mid-80s with cooling sea breezes and warm ocean water ideal for snorkeling, kayaking, and boating. Afternoon showers may pass through briefly, but they’re always followed by bright skies and unforgettable sunsets. It’s also a season filled with culture. May and June feature beloved local events, from live music and art festivals to celebrations that showcase the island’s creative and culinary soul. Staying a little longer allows you to enjoy events naturally, without packing your days or racing from one highlight to the next.
