The climate of Guernsey
The Isle of Guernsey is one of the Channel Isles. Just like Jersey it
is situated fairly close to the French coast. Therefore the moderate
maritime climate very much resembles the climate of the region of
Brittany in France. Compared with the inland of Brittany Guernsey has
milder weather in the winter months. Under the influence of the
relatively warm sea-water it cools down less strongly than the
European continent. The capital of Saint Peter Port has, due to its
favorable situation on the east coast of Guernsey, a strikingly small
number of days that it actually comes to frost. Even in the coolest
months the temperature often stays above freezing-point at night. With
an average of 4 to 6 degrees above zero it is some five to seven
degrees warmer than in the mainland of Great Britain.
The mild winters and the reasonably steady pattern of precipitation
make it possible for subtropical plants such as palm trees to survive
very well on the Isle of Guernsey. However it might be possible wine
is not produced on a large scale in Guernsey. The winter months are not
only reasonably warm, but the sun also appears regularly considering
the region. In the darkest months minimal appr. two hours of sunshine
a day is still registered. The summer months are good for no fewer than
at least an average of eight hours of sunshine a day. With an average
of 35 to 45 millimeters of precipitation per month the summer is drier
than the rest of the year. Concerning the statistics of precipitation
Guernsey does even considerably better than many West European
countries in the summer months.
The summers are seldom hot in Guernsey. Anyone who wants tropical
temperatures better looks for another holiday destination. However
anyone who looks for sunny and dry weather with agreeable temperatures
between 18 and 23 degrees is lucky in Guernsey. Therefore the isle is
extremely suitable for all kinds of outdoor activities such as walking
and cycling. It is not for nothing that you can find many walking- and
cycling routes where you can enjoy yourself excellently. In the
summer months also various festivals and other events are organized.

Remark: Slight deviations may locally 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:
