Come to where the weather is!
It is said that in the Hebrides you will sometimes experience all four seasons in one day. Certainly the weather is varied, particularly in low-lying Berneray where rain showers often blow through rapidly to leave much sunnier conditions than in the more mountainous areas.
Having said that, we have a maritime climate and rainfall totals are high, so you need to be prepared for that. However the wind is the most prominent feature of the climate here. Extreme weather enthusiasts may well find that winter is the best time of year to visit, when you can really experience the awesome power of Atlantic weather systems as they come barrelling in from the west.
The anemometer you can see spinning away from your bedroom window is a part of the Isle of Berneray Weather Station, which is also situated at the property. This features state-of-the-art measuring equipment to create a computerised log of current weather conditions 24 hours a day. This data is also fed to the internet and can be viewed at Weather Underground.
