The best time to go to Key Biscayne is during the dry season, from November to April, to enjoy pleasant weather and avoid the peak hurricane season.During these months, you can expect comfortable temperatures, typically ranging from the low 20s to high 20s Celsius, with lower humidity and less chance of rain. This makes it ideal for outdoor activities like visiting Bill Baggs Cape Florida State Park, where you can explore the historic lighthouse and enjoy the beach.Families often find this period superb for a relaxed holiday. The calmer seas are great for swimming and snorkelling, and the mild weather allows for comfortable exploration of the island's natural beauty without the intense heat and humidity of summer. It's also a good time for paddleboarding or kayaking in the clear waters around the Key.While this is the most popular time, you might find slightly higher prices and more visitors.
