The weather can have a big influence on island life… We rely on the wind and sun to provide electricity.
The ferry and airline services do their best but at times Mother Nature demands a break in services…
There’s something pretty special about having to live in harmony with whatever the weather is providing at any particular time… It’s all part of the total experience of living off the grid on a beautiful remote island.
