Climate
The long-term mean annual precipitation varies from about 2300 mm (lower elevations) to 3550 mm (upper parts). Most of the precipitation (80%) falls between November and April, typically during long-duration frontal storms of low to moderate intensity. In the small catchments precipitation falls mainly as rainfall with snow more common at higher elevations of LOOK. While winters are generally wet and mild, summers are dry and rather cool (average of 18 °C in July).
