Jamaica (Montego Bay) Weather in May

May is Jamaica's wettest month on record, 22.9 rain days on average, a real jump from April, while highs climb to 86.6°F and humidity rises to 82%, the highest reading of the year so far.

Lows warm to 75.3°F, and despite the frequent rain, most of it still arrives as tropical showers rather than sustained systems, with plenty of sun in between.

The sea reaches a warm 84.6°F, among the best swimming conditions of the year, and this holds through the rest of the wet season.

May sits in a genuine value window: winter high season is over, and rates on the north coast typically ease meaningfully for weather that's still mostly workable for a beach-focused trip.

Hurricane season officially begins June 1, so May remains outside the historical risk window, though the shift toward wetter, more unsettled weather is already fully underway by this point.

Dunn's River Falls, the Martha Brae rafting trip and Negril's Seven Mile Beach all remain popular excursions through May, with warm water and generally clear mornings before any afternoon showers build.

This is also a comfortable month for exploring Montego Bay's Hip Strip nightlife and dining scene, since evenings tend to be drier than the daytime shower pattern.

Pack for heat and humidity, plus a genuine rain layer, May's frequent showers make it worth having reliable rain gear rather than relying on sun for the whole trip.
