Consistent weather patterns make St. Martin a great place to plan a vacation because tourists know that no matter when they visit, they'll be able to spend their days doing whatever they choose without severe weather pushing them indoors. 

In truth, no matter when you visit it is possible to experience a bit of rain.  Fortunately, rainstorms pass by quickly.   Often, they seem to appear as if from nowhere, the skies darkening ominously and within moments rain bursts down from the skies, dumping water down in droves for about 20 minutes, then moving on, leaving behind clear blue and sunny skies.  The lack of very tall mountains and tropical forests keep the overall annual rainfall amounts low, and you can expect about 40 inches of rain to be collected in an entire year, with about 58 percent of the days experiencing some amount of rain.

If you're planning ahead, bringing along a umbrella will generally be enough to keep you out exploring the island, or you could simply have a nearby back up plan in mind for all of your desired outdoor activities.
