Climate and weather in Yosemite

Understanding the Mediterranean mountain climate of Yosemite National Park

Yosemite enjoys a Mediterranean mountain climate with significant variations depending on altitude. The influences of the Sierra Nevada create distinct microclimates between the valley (1,200m / 3,937ft) and the high plateaus (4,000m / 13,123ft).

Yosemite Valley (1,200m / 3,937ft): Temperate climate with hot, dry summers and mild, wet winters
Subalpine zone (1,500-2,400m / 4,921-7,874ft): Cooler temperatures, significant winter snow
Alpine zone (2,400m+ / 7,874ft+): Harsh mountain climate, snow 6-8 months per year

January	-2/11°C / 28/52°F	165mm / 6.5in	5	⭐	Cross-country skiing, snowshoeing

December	-1/11°C / 30/52°F	150mm / 5.9in	5	⭐	Snowy landscapes

Altitude variations from 1,200 to 4,000 meters (3,937 to 13,123ft) create temperature differences of up to 15°C / 27°F between the valley and the peaks. This altitudinal diversity directly influences trail accessibility and seasonal blooming.
