Climate overview of 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.

Saint Barthélemy has a tropical climate ideal to visit at any time of the year. With a tropical climate, temperatures vary very little throughout the year, with highs ranging from 29°C (84°F) to 32°C (90°F) in August. Average sea and air temperatures move around 27°C (81°F). The year is divided into two seasons—a dry one referred to as Lent (Careme) and a more humid one in winter. Sun is present all year round and Saint Barthélemy has an exceptional record of having no more than 5 days per year without sun.

October can be Saint Barthélemy’s wettest month of the year when precipitation is high, ranging from 126 mm (5 in) rainfall to 138 mm (5.4 in) rainfall in Gustavia.

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. Known as one of the finest beaches in Saint Barthélemy, Colombier Beach is a serene paradise of transparent water and white sand. Away from the bustling cities, getting to the beach involves a 20-minute excursion, passing through the island’s rich vegetation and wildlife—turtles, iguanas, and lizards. A good part of Colombier Beach’s seabed is considered a natural reserve.

Apart from the weather, we recommend the months from December to April so you would not miss the island’s highlights for a more memorable trip.
