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.
Temperature & Sunshine
Jersey has an average annual daily temperature of 11.6 degrees Celsius. This is comparable to the south coast of England. On an annual basis, just under two thousand hours of sunshine are recorded. The summer months are particularly sunny, with an average of 8 hours of sunshine per day. Many tropical destinations do not reach this number. In the winter months it is a few degrees warmer than in the Netherlands. Also compared to the French mainland, the winters on Jersey are with considerably less frost and snow. During the day the temperature rarely drops below freezing and at night it is often limited to some light frost when it gets really cold. In summer, the daytime temperature is around twenty degrees. On average, not great weather for a sun holiday, but excellent weather to enjoy the island. During warmer periods, summer temperatures can reach around or even slightly above 25 degrees. Tropical values of thirty degrees or even more are not often observed.
With 175 rainy days per year, Jersey is not particularly wet or dry. In the winter months there is on average quite a lot of rain. The months of December, January and February register – based on long-term averages – more than one hundred millimeters per month. Summers, on the other hand, are quite dry. In the middle of summer there is an average of only about forty to fifty millimeters per month, which means that Jersey is relatively dry.
