What to expect in the worst months
August. Daytime highs averaging 36°C / 98°F mean outdoor sightseeing between roughly 11 a.m. and 4 p.m. becomes uncomfortable — locals retreat indoors and many smaller shops close in the afternoon. This is peak hurricane season — disruptive weather can shut down flights, boats, and outdoor activities at short notice.
September. Daytime highs averaging 34°C / 94°F mean outdoor sightseeing between roughly 11 a.m. and 4 p.m. becomes uncomfortable — locals retreat indoors and many smaller shops close in the afternoon. This is peak hurricane season — disruptive weather can shut down flights, boats, and outdoor activities at short notice.
October. Highs in the 30°C range are tolerable in the shade but draining if you're walking all day. This is peak hurricane season — disruptive weather can shut down flights, boats, and outdoor activities at short notice.
