Summer (June-August) – the islands boast 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 islands when the tourists have all gone home. October is peak bird-watching season when the rare migrant species travel through the islands.
Winter (December-February) – Low Season. A season with unpredictable weather and very few tourists. Some properties, attractions and shops close during this period and some of the islanders return to the mainland. That being said winter on the islands 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 on the Skybus or Scillonian ferry can be frequently disrupted due to weather.
Spring (March-May) – A lovely time to visit the islands with spring flowers in bloom everywhere and puffins returning to the outer islands. Temperatures are starting to get balmy and a great time for walking the miles of nature trails on offer.
