Based on the Köppen climate classification, Rhino Peak is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers.[5] Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Temperatures can drop below −20 °C with wind chill factors below −30 °C. The month of July offers the most favorable weather to view or climb Rhino Peak.
