The climate in Saint Martin

St Martin enjoys a tropical maritime climate, which means consistent warm temperatures throughout the year with slight seasonal variations.

The east coast is swept by trade winds that interact with the island’s reliefs, concentrating the clouds.

These clouds condense heat and turn it into the showers, making the vegetation on the leeward coast lush and green.

On the west side, the limestone plateau of Terres Basses is more sheltered from the rains, creating a drier vegetation consisting of scrubland and cacti.
