Alderney — Weather
Alderney is a good way south of the UK so its weather is more in line with that of Normandy, France. Winters are milder, with temperatures averaging 70°F in the warmer months and up to nine hours of full sun. There is also little rain in Alderney—the UK mainland sucks it up—while winds are typically light.
July to August is the hottest and sees the most sun, which is peak season during European school holidays. There are four definite seasons, all of which are pleasant, including winter, which hovers around 50°F. April to June has a dry climate that is less busy, while winter is the wettest time of the year.
Best Time to Visit Alderney
July and August are best for the beach, with daytime temperatures can go well into the 90’s (°F). Although the shore never gets super crowded, hotels do fill up. With that in mind, June and September are probably your best bet for saving some money and less crowds. It’s worth noting though that some attractions are closed in the fall and winter, such as the Alderney Railway, though accommodations are cheaper.
