Guernsey — Weather
If you’re familiar with the unpredictable, often grey UK weather, you may be pleasantly surprised with Guernsey as it has a better climate on account of its more southerly setting. It also feels the effects of the Gulf Stream as much as the mainland, meaning warmer than normal summers and mild winters, and is noted for its dryness and light breezes. There are four Guernsey seasons—spring, summer, fall, winter.
Average temperatures in July-August summer days are between 68°F and 77°F, and winter days usually hover around 50°F. April through June is the driest time to be in Guernsey, with around just five inches of rain over the three month period. In contrast, the winter months of November and December are the dampest, with around four inches of rain a month.
Winter is the off-season for a chance at cheaper hotel rooms and plane tickets. There are always deals to entice travelers, and if you’re lucky, the weather may cooperate. The shoulder season in spring and fall also see cheaper accommodations along with fewer crowds. European school holidays are July-August, the height of high season, when hotels absolutely must be booked in advance.
Best Time to Visit Guernsey
Guernsey receives something like 2,000 hours of sun a year and any time between May and October is a good time to visit. The best time months for the beach are undoubtedly July and August, with the hottest temperatures (days can get up to 95°F) bringing warmer seas.
There is not really a bad time to visit Guernsey as both spring and fall are very nice. The islands don’t suffer extremes in weather—there are no hurricanes or big seasonal winds—and attractions stay open up year-round. Be aware, however, that some cities in Europe only have seasonal flights.
