Good to know

The trade winds drive the spot

St Barth is swept most of the year by the trade winds, a steady breeze from the east and north-east. They are what makes Saint-Jean Bay work for windsurfing, wingfoiling and catamaran sailing: facing north-north-east, the bay takes them head-on or at an angle.

Over a day, the wind measured at the spot is often lighter at night and in the morning, then builds around midday. The 24-hour average therefore smooths out afternoons that are windier than it suggests: to pick a session, rely on the hourly forecast and the live wind.

Frequently asked questions

Where does the wind come from in St Barth?

Which month is the windiest?

The “Month by month” table compares average wind, gusts and the number of windy days measured by the spot station; it grows every month.

Is the 7-day wind forecast reliable?

It comes from the European ECMWF model and becomes less precise day after day. For the next 48 hours, the dashboard uses Météo-France’s finer AROME model.
