'''Mount Sealy''' is a {{convert|2627|metre|ft|adj=mid|-elevation|abbr=off}} mountain in Canterbury Region of New Zealand.
==Description== Mount Sealy is located in the Southern Alps and the Canterbury Region of South Island. This peak is situated {{convert|5|km|mi|spell=in}} southwest of Mount Cook Village and set within Aoraki / Mount Cook National Park. Precipitation runoff from the mountain drains south into the headwaters of the Dobson River, and north to the Hooker River. Topographic relief is significant as the summit rises {{convert|1050.|m|ft|abbr=off}} above the Dobson headwaters in one kilometre. The nearest higher neighbour is Mount Burns, three kilometres to the west-northwest.<ref name=peakbagger/> The mountain's toponym was applied by Julius von Haast to honour Edward Sealy (1839–1903), a New Zealand surveyor, photographer, and explorer.<ref name=NZGB>[https://gazetteer.linz.govt.nz/place/31697 ''Mount Sealy''], New Zealand Gazetteer, Retrieved 1 January 2025.</ref>
==Climbing== The first ascent of the summit was made in January 1895 by Jack Clarke, C.L. Barrow, and Edward FitzGerald via the East Ridge.<ref name=climbnz>[https://climbnz.org.nz/nz/si/aoraki/sealy-range/mt-sealy ''Mt Sealy''], New Zealand Alpine Club, Climbnz.org, Retrieved 1 January 2025.</ref>

==Climate== Based on the Köppen climate classification, Mount Sealy is located in a marine west coast (Cfb) climate zone, with a subpolar oceanic climate (Cfc) at the summit.<ref>[https://en.climate-data.org/oceania/new-zealand/canterbury/christchurch-4978/ ''Christchurch Climate (New Zealand)''], climate-data.org, Retrieved 1 January 2025.</ref> Prevailing westerly winds blow moist air from the Tasman Sea onto the mountains, where the air is forced upward by the mountains (orographic lift), causing moisture to drop in the form of rain or snow. This climate supports the Metelille and Sladden glaciers on the north and west slopes of the peak. The months of December through February offer the most favourable weather for viewing or climbing this peak.<ref>[https://nzpocketguide.com/the-best-time-to-visit-the-south-island/ ''The Best Time to Visit the South Island''], nzpocketguide.com, Retrieved 1 January 2025.</ref>
