), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports an unnamed glacier on the northwest slope. The months July through September offer the most favorable weather for climbing Tenquille Mountain.
