What is the Weather like?

One of the most important questions for vacationers is “What’s the weather like in….?” Most of the times, there is an easy answer for Dutch Sint Maarten and French Saint Martin: It’s picture perfect!

There is no specific rainy season on the island, but one does exist for hurricanes. The months of July to November harbor some hurricane risk. The highest likelihood is in the middle of September. These months can still be very nice and hurricanes hit the island not every year.

The average temperature of the crystal clear waters surrounding St Maarten & St Martin ranges from 78-80F in the winter, and 82 F-84 F in the summer. Below table shows the monthly average temperatures and rainfall for the island, which is blessed with sun almost year round.

The winds blow a fairly regular 15 knots from mid-November to mid-April. In the summer, thermal effects and tropical waves can bring a bit stronger drafts, and rain showers are to be expected. They are usually brief, but intense. Temperatures as shown on this site usually refer to the weather station at Princess Juliana Airport (SXM).
