Climate - The High Sierra generally experiences warm, dry summers and cold, snowy and wet winters. Weather can change rapidly during all seasons of the year. Elevation plays a major role in temperature and precipitation. This precipitation falls mainly from October through April. At higher elevations, it comes mostly in the form of snow. A snowpack from 5-10 feet or more is usually present from December to May at elevations above 6,500 feet. Winter temperatures below zero and summer temperatures above 100 degrees indicate the normal seasonal spread. Clouds can build up during the summer to produce spectacular thunderstorm activity. It is wise to pack for any season with clothing that can be "layered," ready to peel off or add on as the thermometer dictates. Always include some kind of rain gear.
