Traveller notes on Negril in September
Other months in Negril
Negril's forum calls January about as reliable as it gets — sunny days with maybe a brief, 15-20 minute tropical shower in the late afternoon before the sun's back out. The one wrinkle regulars flag: Jamaica gets the odd cold front from the north between late January and early February, so a lightweight jacket and long sleeves are worth packing just in case.
