St. Maarten weather in October takes a small break from the heavy rains that typically fall during the peak months of the Caribbean hurricane season.

It’s a surprising change for the bad weather that typically hits the Caribbean, especially in September and October.

The official Caribbean hurricane season runs from June 1 through Nov. 30. September and October get the worst of it for many destinations.

Most islands don’t experience any direct impact of hurricanes or tropical storms. Most vacationers are simply stuck in their hotel rooms for a day or two while the bad weather comes and goes.

St. Maarten doesn’t exactly get away from the bad stuff in October, but it does better than September and especially November.

The following numbers are based on a 30-year summary of the island’s weather. Actual results will vary from year to year.

Whether to Go

Whether to go to St. Maarten in October is not as easy of a decision as whether to go to Cozumel in October. That Mexican island usually gets drenched during the month.

If October is the preferred month for vacationing in the Caribbean, other islands have lower chances of rainfall, especially Aruba.

If St. Maarten is the preferred choice and any month is an option, then January through July are better choices because of much lower risk of rain.
