Guernsey Climate & Weather

Guernsey Climate and Weather

The Channel Islands have a maritime climate, with moderate temperatures throughout the year, partly because the islands are well-protected by France and England, which block the worst of the wind. Guernsey experiences a temperate climate with mild winter weather and cool sunny summers. In summer, between June and September, temperatures average around 68°F (20°C), but often reach 75°F (24°C). July and August are the hottest months, and July is the sunniest, although it is common for days to be overcast on Guernsey at any time of year. In winter, between December and March, temperatures average about 42.8°F (6°C), and seldom drop below freezing, although 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 November, December 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.
