St Kilda is probably the windiest place in Britain. There are gales for 20% of the year - that's 75 days out of 365!
St Kilda very rarely has snow and its climate is generally cool and wet. Big squally showers and winds rattle across the islands at all times of the year. In the winter this can cause a lot of damage to the buildings on the islands. When you are out on St Kilda you can see these squalls coming in from the west and they suddenly hit the islands for about 15 minutes and then they're gone. You are very close to the weather out there!
