Saint Barthélemy in December

December through May delivers perfect weather with temperatures in the low 80s and minimal rainfall. This is also peak season, so hotel rates triple and restaurants require reservations weeks in advance. January and February see the biggest crowds, especially around New Year's when mega-yachts fill Gustavia harbor. March and April offer slightly better deals with the same great weather. Hurricane season runs June through November, but St. Barts sits far enough south to avoid most major storms. July and August bring more rain and humidity, plus the risk of tropical weather. But here's the upside — hotel rates drop by 40% and you'll have beaches mostly to yourself. September and October are the wettest months, though rain usually comes in short bursts rather than all-day downpours. November starts the transition back to dry season, with improving weather and rising prices. The island basically shuts down in September, with many restaurants and hotels closing for maintenance.
