The best time to visit Alderney is during the summer months, from June to September, when the weather is at its most pleasant.
During this period, you can expect warmer temperatures and longer daylight hours, which are ideal for exploring the island's natural beauty and enjoying outdoor activities. The sea temperatures are also warmer, making it great for swimming, coasteering, or kayaking around the coastline.
Couples looking for a relaxing getaway will appreciate the island's tranquil pace during these months. You can enjoy strolls along the beaches like Braye Bay, explore the network of historic fortifications, or simply unwind at one of the local eateries. The longer days mean more time to take in the stunning sunsets over the English Channel.
For those interested in wildlife, particularly birdwatching, late spring (May) and early autumn (September) can also be excellent. These shoulder seasons often see migratory birds passing through, and the puffin colonies at Burhou are most active from April to July.
