Climate and Average Weather in Saint Barthélemy

An island in the Lesser Antilles known for its exceptional aquatic fauna and flora, the French island of Saint Barthélemy, often abbreviated to St. Barths or St. Barts, is making waves for its serene beaches and landscapes. Dubbed the "Saint-Tropez of the Caribbean", Saint Barthélemy has managed to preserve the charm of its wild nature. Travelers will undoubtedly fall under the spell of the idyllic white sand beaches and turquoise waters of this true tropical paradise.

Average sea and air temperatures move around 27 degrees Celsius (80° Fahrenheit). The year is divided into two seasons—a dry one referred to as Lent (Careme) and a more humid one in winter.

Crystalline water and clear sand make for an extraordinary escapade, ideal to unwind and sit under the sun without many people—and Saint Barthélemy knows this with its Colombier Beach.
