The climate of Jersey
The Isle of Jersey belongs to the Channel Islands and lies in front of
the coast of France in the vicinity of Brittany and Normandy. Jersey
has a moderate maritime climate with mild winters and not too warm
summers. According to the Köppen climate classification the Channel
Isle of Jersey has a Cfb climate. Due to its situation in front of the
French coast it benefits from the warm gulf stream in the winter
months,
which causes relatively warm sea-water. A consequence of the warm
sea-water is that the air temperatures in the winter months do not
easily drop below freezing-point. But the Isle is very sensitive to
strong winds and even storms reaching the Channel from a western
direction via The Atlantic. Therefore heavy storms with windforce 8, 9
or even 10 occur minimally a few times a year. In the summer months
however the chance of these storms is small.
Temperature and sunshine
Jersey has an average annual 24 hour temperature of 11,6 degrees
centigrade. This is comparable with the south coast of England. On a
yearly basis a little fewer than two-thousand hours of sunshine are
registered. Particularly the summer months are reasonably sunny with an
average of 8 sunny hours a day. Many tropical destinations do not
reach this score. In the winter months it is a few degrees warmer than
in the Netherlands. Also in respect of the French continent the
winters in Jersey pass with considerably less frost and snow. During
the daytime the temperature seldom drops below freezing-point and at
night it is often limited to slight night frost if it gets really cold.
In the summer during the daytime the temperature is approximately
twenty degrees. On an average no super weather for a sunny holiday, but
excellent weather to enjoy the Isle. During warmer periods
temperatures in the summer can rise to about or even a little above 25
degrees. However tropical values of thirty degrees or even more are
not registered that often. With 175 rainy days per year Jersey cannot
be called distinctly wet or dry. In the winter months there is on an
average fairly much rain. In the months of December, January and
February more than a hundred millimeters per month are registered
based on averages of more than one year. On the other hand the summers
are rather dry. In the height of summer there is on an average only
some forty to fifty millimeters per month with which Jersey is
relatively dry. Climate figures
The figures below are based on registered weather information of
more than one year and are an average for Jersey.
Remark: locally slight deviations may occur.
More climate information
Climate figures come in handy but do not offer a total impression of
the climate and the possible weather circumstances within a particular
period. You cannot often find in figures how big the chance is of
wintry weather, (extreme) heat or hurricanes. Therefore we monthly
offer useful extra climate information.
