St. Maarten Weather - When to Go, When to Stay Away


St. Maarten climate is the same whether you go to the Dutch side or the French side -- it's warm year round, but watch out for rain in the fall.

The island, smallest in the world shared by two nations, is a mix of Dutch and French cultures that make it a popular destination for eastern and southern Caribbean cruises. The weather is warm and sunny eight months of the year, but rain is a factor during the other four months.

St. Maarten climate is warm year-round because it is located in the southern Caribbean and closer to the equator than most islands.


The average monthly high temperature is about 86 degrees Fahrenheit and the average monthly low is about 77 degrees, according to the Meteorological Service of Netherland Antilles and Aruba.

The monthly high temperatures climb to an average of 88 to 89 degrees in June through October. They drop to about 84 degrees from December through March.

Although the seawater is comfortable enough for swimming year round, it will reach a low point in comfort level from January through March when temperatures reach their lowest point.
