The best time to visit St. Barth’s is between the months of December to May, when the weather is beautiful, and the chances of rain are lowest.
Hurricane season begins in June and ends in November, but that doesn’t mean it’s a bad time to visit, just be prepared for potentially bad weather during those months.
Keep in mind that high season on the island runs from December to April, with the busiest times being in December and January. Hotels and villas may be fully booked and prices may be higher during those months. Low season starts in April, with August and September being the quietest months to visit.
