Climate & Weather Guide in Sint Maarten

Climate zones, seasonal temperatures, rainfall patterns, and best travel times

Sint Maarten has a hot tropical maritime climate shaped by the northeast trade winds and the surrounding Caribbean Sea. It is small and geographically homogeneous, so one climate zone is sufficient. The island’s climate is warm year-round, with only modest seasonal change, and rainfall is concentrated in the wet season from late summer into early winter. Official and local climate resources describe the island as vulnerable to heat, heavy showers, hurricanes, and drought variability, which matters for residents and expats planning housing, utilities, and outdoor routines. Recent local climate platforms and rainfall records support a generally humid, sunny island climate with moderate annual precipitation.
