Jamaica's rainy season coincides with ours here in Florida (I am in the Tampa area) for the most part. We have anywhere from 30-50% chance of rain daily until hurricane season is over. I didn't mean you have rain every day, all day from May to December in Jamaica, but I assume it is a lot like here in Florida.
Come Spring, the average annual temperature is close to 82 Â°F. The months of March and April are filled with sunny days, so take advantage of that climate and spend time outdoors before May starts. In May is when the rain really starts to fall. This is the coolest resort area in Jamaica.
