Ocho Rios has a pleasant climate but can get muggy in the summer months. Temperatures average 80-86 F/26-30 C year-round, and a refreshing trade wind is usually blowing. In winter months, temperatures can drop considerably when rare cold fronts bear down from as far away as Canada.
Rainfall is possible any time of year, although the majority of rains fall in summer months (May-November), usually as afternoon downpours. Lingering storms can deluge the area during this time, when hurricanes are also possible. Hurricane season is June-November.
The best time to visit is November-April, but the main resorts can be very crowded then.
