Summer (June-August) – the island boasts some of the UK’s warmest weather and temperatures can reach a comfortable 21 degrees Celsius. This period is peak season and although the weather is favourable, costs and availability can be an issue.
Autumn (September-November) – September to mid-October can still attract some decent weather and it means you can enjoy the island when the tourists have all gone home. The sea temperatures tend to be at their warmest in September.
Winter (December-February) – Low Season. A season with unpredictable weather and very few tourists. Some properties, attractions and shops close during this period. That being said winter on Guernsey can still be enjoyable, with dramatic coastlines and cosy atmospheric pubs whilst taking advantage of the much lower prices at this time of year. However please bear in mind that travel to Guernsey at this time of the year can often be disrupted due to weather. This is also the best time for deserted beaches, coastal foraging, stormy photography and wild walks without another soul in sight.
Spring (March-May) – A lovely time to visit the island with spring flowers in bloom everywhere and the summer hoards of visitors have not yet arrived. Temperatures are starting to get balmy and a great time for walking the miles of nature trails on offer.
