We had to schedule our vacation in September. I have read conflicting info, but in large it appears that September is still the rainy season, but it is between the summer and fall peaks. We read that Negril is on the dry side of the island? Is that true? What is the weather like there during september? We were thinking of breaking in CTI, but we thought it best to stick to the dry side of the island during the rainy season....but who know if what we read is true.
