Hurricanes
In the period from June to November (but mostly from August to October), Sint Maarten can be hit by tropical depressions and
hurricanes, as happens in general in the Caribbean.
When to go
The best time to visit the island where Sint Maarten is located goes
from December to April, since it is the least hot period of the year and outside the hurricane season; in particular, the period from February to March is usually the least rainy.
In May, both temperature and moisture increase, but the rains are not yet too abundant, and the hurricane season has not yet begun.
In summer, June and July are not as rainy as August and September, in addition, tropical storms and hurricanes are less likely to occur than in the following months.
What to pack
All year round: bring
light clothes of natural fabric, and possibly a light sweatshirt and a light raincoat for thunderstorms, especially from August to November. From December to March, you can add a light sweatshirt for the evening.
When going to the reef, you can bring snorkeling equipment, including water shoes or rubber-soled shoes.
