Based on the Köppen climate classification, Remote Mountain is located in the marine west coast climate zone. Most weather fronts originate in the Pacific Ocean and travel east toward the Coast Mountains where they are forced upward by the range, 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. Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Fan Glacier and unnamed glaciers which surround the slopes of Remote Mountain.
