The best months to visit St. Barts are December through April, known as the "Signature Season." During this window, the weather is nearly perfect, with low humidity, clear blue skies, and comfortable daytime temperatures in the mid-70s to low 80s (°F). This is the height of the island's social scene, culminating in the famous New Year's Eve yacht parties and the Bucket Regatta in March. If you want to avoid the highest prices and densest crowds, May and June are the "sweet spot" shoulder months; the weather remains dry and warm, but villa rates often drop significantly. You should generally avoid September and October, which are the peak of the Atlantic hurricane season; many of the island’s most famous restaurants and boutiques actually close during this time for their own staff vacations and annual maintenance.
