ClimateMount Challenger is located in the marine west coast climate zone of western North America.[6] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall onto the Cascades. As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.[6] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below {{convert|0|°F|°C}} or above {{convert|80|°F|°C}}.[6] During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.[7] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[7] References1. ^1 {{cite peakbagger|pid=1650|name=Mount Challenger, Washington|accessdate=March 31, 2013}} {{DEFAULTSORT:Challenger}}2. ^{{cite gnis|id=1517614|name=Mount Challenger|accessdate=March 31, 2013}} 3. ^{{Cite map|publisher=TopoQwest (United States Geological Survey Maps)|title=Mount Challenger, WA|url=http://www.topoquest.com/map.php?lat=48.83568&lon=-121.34235&datum=nad83&zoom=4|accessdate=March 31, 2013}} 4. ^{{cite book|last=Beckey|first=Fred|title=Cascade Alpine Guide: Climbing and High Routes Rainy Pass to Fraser River|year=2008|publisher=The Mountaineers Books|isbn=978-1594851360|page=122|url=http://www.mountaineersbooks.org/Cascade-Alpine-Guide-Vol-3-Rainy-Pass-to-Fraser-River-ebook-P757.aspx|accessdate=22 December 2013}} 5. ^{{cite book|last1=Nelson|first1=Jim|title=Selected Climbs in the Cascades:, Volume 1|year=2003|publisher=The Mountaineers Books|isbn=978-0-89886-767-1|page=274|editor=Peter Potterfield |url=http://www.mountaineersbooks.org/Selected-Climbs-in-the-Cascades-Vol-1-2nd-Edition-P281.aspx|accessdate=22 December 2013}} 6. ^1 2 Beckey, p. 15 7. ^1 Beckey, p. 16 3 : Mountains of Washington (state)|North Cascades National Park|Mountains of Whatcom County, Washington |
