have been at different times in the year, and to be honest overall the weather seems always the same.  You will have glorious sunshine one minute and the next it will pour down with rain (liquid sunshine) and then its sunny again.  Never cold.  Obviously if you go later in the year i.e. late sept, oct etc there are greater chances of the hurricanes, but nothing to really worry about.  Always bring holiday clothes especially if your a brit cause its very warm.  If your from Florida etc, then it may not been anything unusual, as you are used to fantastic weather!
