The best time to go to Little French Key is during the dry season, which runs from February to September.This period offers the most consistent sunshine and calm waters, making it ideal for enjoying all the island's activities. You'll find the weather warm and pleasant, great for relaxing on the beaches or exploring the marine life.For those who prioritise avoiding crowds and potentially finding better value, the shoulder months of February, May, and September are excellent choices. The weather is still superb, but you'll experience a more tranquil visit before or after the peak tourist rushes. This can be particularly appealing for couples looking for a more intimate getaway.While the wet season (October to January) can bring more rain, it often comes in short, heavy bursts, and there are still plenty of sunny days.
