I remember all the rain last year... I arrived late afternoon the last day of the week of endless rain. Then it was back to normal, i.e., perfect. I was going in May (years ago for about 5 years), then it's been in June & July for the last 20 years. It doesn't rain every day, usually starts later in the afternoon & then becomes earlier & earlier in the day as the summer progresses. It also does not rain every day. I've kept logs the last few years. 50% - 60% of the time... no rain at all. By mid July it might start raining by noon. Where you stay on the beach also makes a difference. Closer to town... not so much rain. Treehouse, AI area... rain. It's fascinated me for years that it can be as beautiful as can be at Traveller's, Beach Club, Shield's, etc. & it's pouring at the other end of the beach. Some days the rain will travel down & "wet up" that end of the beach; most often, it does not. Rain or not, Negril is a great place to be this time of year.
