The weather in the Channel Islands is broadly similar to the UK's climate, although noticeably warmer and sunnier. Temperatures are moderate all year round, and rain is a regular companion. Winters are damp and often blustery, while summers are warm and bright. The islands rarely experience dramatic temperature swings or extreme weather.
Jersey, as the southernmost island, tends to be a degree or two warmer than Guernsey and the smaller islands of Alderney and Sark, although all share the same temperate oceanic character.
July and August are the warmest months. Maximum temperatures hover between 66°F (19°C) and 71°F (22°C). January and February are the coolest months, with typical maximum temperatures ranging between 46°F (8°C) and 50°F (10°C). The wettest period runs from autumn into early winter, with December seeing the heaviest rainfall. Snow is possible in winter, but it is a rare occurrence.
