The balmy, tropical climate is cooled by constant sea breezes but is still sunnier and drier than the other islands. The dry season is from December to June; during the so-called wet season (July to November), some brief rain showers are likely. Average sunshine hours per day are eight to 10 from November to March and eight to nine from April to October. Tropical storms and hurricanes may occur between June and November.

Lightweight cottons are advised; beachwear is not worn in towns.
