==Climate== Based on the Köppen climate classification, Tupopdan is located in a tundra climate zone with cold, snowy winters, and cool summers.<ref name=Peel>{{cite journal | author = Peel, M. C. |author2=Finlayson, B. L. |author3=McMahon, T. A. | year = 2007 | title = Updated world map of the Köppen−Geiger climate classification | journal = Hydrol. Earth Syst. Sci. | volume = 11 | issn = 1027-5606}}</ref> Weather systems are forced upwards by the mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. This climate supports two unnamed glaciers descending from the north slope. The summer months offer the most favorable weather for viewing or climbing this peak.<ref>[https://www.travelertrails.com/places-to-visit-in-hunza/passu-cones ''Passu Cones''], TravelerTrails, travelertrails.com, Retrieved June 1, 2025.</ref>
