Sir William Peak is a 2,610-metre-elevation (8,563-foot) mountain in Otago, New Zealand.
Description
Sir William Peak is located 28 kilometres north of Glenorchy, New Zealand, in the Southern Alps of the South Island. It is set within Mount Aspiring National Park which is part of the Te Wahipounamu UNESCO World Heritage Site. The peak is part of the Forbes Mountains which are a subrange of the Southern Alps. Precipitation runoff from the mountain's southwest slope drains to the Dart River / Te Awa Whakatipu via Bedford Stream, whereas all other slopes drain to the Rees River via Hunter Creek. Topographic relief is significant as the summit rises 2,150 metres (7,054 feet) above the Dart Valley in five kilometres, and 1,300 metres (4,265 feet) above the West Branch of Hunter Creek in 1.5 kilometre. The nearest higher neighbour is Mount Earnslaw, three kilometres to the south. This mountain's toponym has been officially approved by the New Zealand Geographic Board.
Climate
Based on the Köppen climate classification, Sir William Peak is located in a marine west coast climate zone, with a subpolar oceanic climate (Cfc) at the summit. Prevailing westerly winds blow moist air from the Tasman Sea onto the mountain, where the air is forced upwards by the mountains (orographic lift), causing moisture to drop in the form of rain and snow. This climate supports the Frances Glacier on the southwest slope and an unnamed glacier on the east slope of the mountain. The months of December through February offer the most favourable weather for viewing or climbing this peak.
Climbing
The first ascent of the summit was made in December 1930 by J.A. Sim, V.J. Leader, and K. Grinling.
