Weather in Eastern California: Seasonal Patterns

Eastern California's weather varies dramatically by sub-region (Sierra Nevada, Owens Valley, Mojave Desert) and elevation, but general seasonal patterns apply:

• Spring (Mar–May): Mild (60s–80s°F / 16–27°C), wet season with showers/thunderstorms.
• Summer (Jun–Aug): Hot (often >90°F / 32°C+), dry, sunny—especially in valleys and deserts.
• Fall (Sep–Nov): Mild, comfortable (70s–80s°F / 21–27°C), mostly dry.
• Winter (Dec–Feb): Cold (50s°F / 10–15°C highs), wet season; snow at higher elevations (Sierra).

Microclimates matter: Death Valley (Mojave) hits 120°F+; Lake Tahoe (Sierra) gets heavy snow. Always check location-specific forecasts before travel.
