In inland areas, on the slopes of Mount Gimie, rains are more abundant, so that a rainforest grows.
The rains occur throughout the year especially in the form of downpour or thunderstorm, and therefore do not reduce too much the sunshine hours, except when hurricanes
or tropical storms hit the island. These may occur from June to November, but are most likely from August to October, as in general in the Caribbean.
For swimming, the sea is warm throughout the year: the temperature goes from 26 °C in February and March, to 29 °C in September and October.
