The Caribbean has a tropical climate so you'll find hot and sunny weather all year round. Most islands have a rainy season, usually from May to October. You'll get higher temperatures, humidity and more rain at this time.

While the Caribbean is famous for its tropical warmth, it is not strictly "sunny all year round" in the sense of cloudless skies. The region experienced two primary seasons: the dry season (December to May) and the wet season (June to November). During the dry season, you can expect the most consistent sunshine and low humidity, making it the peak travel period. However, the wet season coincides with the Atlantic hurricane season; while it still features plenty of sun, it is characterized by high humidity and sudden, intense tropical downpours that usually pass quickly. In 2026, climate patterns show that even in the "rainy" months, most islands see several hours of bright sunshine daily. Some southern islands, like Aruba, Bonaire, and Curaçao (the ABC islands), sit outside the main hurricane belt and tend to be much more arid and sunny throughout the entire year compared to the more mountainous, lush islands of the Greater Antilles.
