Climate of Jersey

Jersey has a temperate maritime climate, with mild winters and not too warm summers. According to the Köppen climate classification, the Channel Island of Jersey has a Cfb climate. Due to its location off the coast of France, it benefits in the winter months from the warm Gulf Stream, which provides relatively warm seawater. A consequence of the warm seawater is that the air temperatures in the winter months do not easily dip below freezing. The island is sensitive to strong winds and even storms, which reach the Channel from the west via the Atlantic Ocean. Severe storms with wind force 8, 9 or even 10 occur at least a few times a year. In the summer months, however, the chance of this is small.
