Guernsey Climate and Weather

The Channel Islands have a maritime climate, and the destination experiences moderate temperatures throughout the year. Sheltered by England and France, the islands are spared the strong winds of most offshore locations. Winters tend to be damp and cloudy, while summers are warm and sunny. In summer, between June and September, temperatures average around 68F (20C), but often reach 75F (24C).

In winter, between December and March, temperatures average about 42.8F (6C), and seldom drop below freezing. However, the wind-chill from arctic winds can make it very cold. Snow is rare, but is most likely to fall in February, which is the coldest month. Rain is possible at any time of year, but the wettest months are between October and January. June, July, and August are the driest months.

The best time to visit Guernsey is in the summer, between June and September, when it is warm, dry, and most likely to be sunny. May and October are also good months to visit.
