Guernsey Weather

The Channel Islands enjoy the most sunshine of all the British Isles and summer temperatures are very much the same as in some parts of southern England. Just like in the UK, changeable weather is the order of the day, and visitors can expect a mixture of bright skies, clouds and rainfall at any time of the year. Around 50 per cent of days are overcast. The local climate is tempered by its maritime position and does not suffer the extremes of temperatures found in more landlocked areas; thanks to the shelter offered by their giant neighbours they escape the worst of the winds often associated with offshore locations.

Winter

Winters are generally mild, and to some, Guernsey shows its best side outside the main tourist season when the islands beauty can be best enjoyed without the crowds.

Summer

However, visiting Guernsey is enjoyable at any time of the year, even though the best months to travel are May to September, with temperatures averaging 15C. These months see an average of eight hours of sunshine a day. The hottest months are July and August, with average temperatures topping 20C. Furthermore, some attractions only stay open in the summer season.
