Climate

edit

Based on the Köppen climate classification, Llao Rock has a subalpine climate.[5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Cascades where they are forced upward by the range (Orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Cascades experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below 10 °F (−12 °C) with wind chill factors below 0 °F (−18 °C). In the Crater Lake area, winter lasts eight months with an average snowfall of 41 feet (12.5 m) per year.[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.
