The rainfall and unpredictable weather patterns are due the famous ‘Roaring Forties’ westerly air streams. These winds pick up moisture as they cross the Tasman Sea, are pushed up by the mountains then release it as heavy rain in the west and snow at higher levels.
As with alpine areas anywhere in the world, the fabulous views come with exposure to the elements. High and gusty winds, snow are all possible so take care and be aware of the risk of wind chill.
Avalanche risk is high in Fiordland thanks to the steepness of the mountains and the high snowfall. Avalanche risk exists mainly over winter and spring, especially between late August and early November.
