Guernsey weather overview

Guernsey has a delightfully warm summer climate and enjoys mild, if rainy, winters. On the long summer days, between May and September, you can bask in an average of 8 hours of sunshine a day but, if you are planning a walk or a visit to the beach, take a cover-up as those sea breezes can be chilly. Rain falls mainly in the autumn and winter but can occur sporadically in the summer months. Winters are cool but rarely very cold.

What to pack for Guernsey weather

Take relatively warm clothing for the cool winter months and, in the summer, supplement beach wear and light clothing with a warm wrap, just in case. Be prepared for rain at any time of year.
