Weather in St. Martin
 

Being in the tropics, and close to the equator, St. Martin and Sint Maarten experience very little variation in temperature throughout the year. In addition to the temperature, vacationers should consider humidity, tradewinds, rainfall and hurricane season when thinking about the climate of the island.

Temperatures will range anywhere from 75 degrees Fahrenheit in the winter to 90 degrees Fahrenheit in the summer. The average temperature is around 80 degrees Fahrenheit, and this will generally only vary a few degrees, even in the summer months. Humidity, another major climate concern, will also increase in the summer months.

Tradewinds, combined with air conditioning and the water, however, make the increased heat and humidity in the summer months only a minor issue for most vacationers. The island's elevated interior can also offer reprieve from the warmer climate on the outskirts. In the winter temperatures dip somewhat in the morning and evening, occasionally making for a cool night.

Hurricane season starts in the beginning of June and goes through November in the Atlantic. Although hurricane strikes are rare on St. Martin and Sint Maarten, it is during these months that the island experiences the most rainfall. The island receives an average of 40 inches of rainfall a year.  When showers do strike, they are usual come on quickly, end within minutes, and leave the sky as bright and sunny as before they began. 

To avoid the threat of hurricane all together, your best bet is to plan your vacation between the months of December and May.  Still, if you do book your trip during hurricane season, keep an eye on the weather.  Today's meteorological technology will usually be able to predict if a hurricane will ruin your vacation with enough time for you to make other arrangements. If a hurricane has hit shortly before you trip, give your hotel a call to gauge what kind of damage was done, and if a vacation is still salvageable.
