Although St. Martin / St. Maarten experiences a relatively consistent climate throughout the year, there are slight seasonal variations that travelers should be aware of. The island has two main seasons: the dry season and the wet season.
The dry season, which runs from December to April, is the most popular time to visit the island. During these months, rainfall is minimal, and the days are sunny and dry.

The wet season also coincides with the Atlantic hurricane season, which officially runs from June 1 to November 30. While hurricanes are not common, it’s important for travelers to stay informed about potential storms during this period.
Humidity levels on St. Martin / St. Maarten are generally moderate, averaging around 75% to 80% throughout the year.
