For those posting the question and/or concern about an upcoming trip you need to understand something about Jamaica. First, the forecasts are very general for the entire island and you can toss the on-line forecasts out the window.

Jamaica has mountains in the centre of the island. It is a big island that has micro-systems of climate. On one quarter of the island it could be totally opposite to anywhere else. Jamaica has tropical rainforests and dry lands where cactus grow with everything else possible in between. Clouds form every day over the mountains. You can be assured that it will rain somewhere every day much like the forecasts predict. Where, or when who knows. When it does it lasts up to an hour or so and generally in mid to late afternoon. It could rain from one cloud a mile away but not where you are.

Forecasters cannot predict weather accurately in Jamaica for the next day, unless there is a hurricane, let alone a week from any given day. When they say there is a 60% chance of rain they are probably correct but that does not mean where you are. Stop worrying about it. Truth is if it rains it's a way to enjoy other things while it cools down the heat of the day. Locals call it "liquid sunshine".
