Caye Caulker stays at a comfortable 70-80 degrees year round, so you can visit any month of the year and still get some sun.
The dry season in Belize is between November-April, and the rainy season starts around June or July. Rain only comes in short bursts though, and helps to cool down the hot summer temperatures, so you can still enjoy Caye Caulker during the rainy season.
Depending on your tastes, the best time to visit Caye Caulker might be during its annual Lobster Fest. This famous festival takes place at the end of June, and is the ‘Biggest Lobster Fest in Belize’. Not only will you get to sample massive lobster, but there are also fun activities like a Lobster Fest Pageant, live performances, and beach parties.
