Yosemite weather today, as shown in the live forecast above, reflects the Sierra Nevada’s spring pattern: daytime highs climb into the comfortable range at lower elevations while lingering snowpack persists at higher passes, with overnight lows near freezing.
How does Yosemite weather change by month?
Yosemite weather by month follows a distinct seasonal rhythm. Summer (June–August) brings dry, sunny days with valley highs around 28–32 °C and cool nights near 7 °C. Winter (December–February) sees frequent snowfall, especially above 1,500 metres, with valley highs near 8 °C and lows below freezing. Spring and autumn offer milder temperatures but variable conditions, including late snow in April and early storms in October.
What should you know about snow and elevation?
Snow is a defining feature of Yosemite weather snow, particularly from November through May. The higher you go, the more snow you’ll find—Tioga Pass often remains closed into June. The live forecast above shows current conditions, but for longer-range planning, the yosemite weather 10 day and yosemite valley weather 14 day forecasts are helpful. For a broader outlook, the yosemite weather 20 day forecast and yosemite weather forecast 30 day provide general trends, though accuracy decreases at longer ranges.
What is the best month for clear skies?
September typically offers the most stable weather: warm days, cool nights, and minimal precipitation. Wildfire smoke can occasionally reduce visibility, so check the live forecast above before your trip.
Does Yosemite get severe thunderstorms?
Yes, especially in late summer. Afternoon thunderstorms develop over the Sierra crest, bringing lightning, gusty winds and brief heavy rain. Hikers should plan to be below tree line by early afternoon.
How should I dress for a visit in spring?
Layers are essential. Mornings and evenings can be near 0 °C in the valley, while afternoons may reach 15–20 °C. A waterproof jacket is wise, as spring showers and sudden snow at higher elevations are common.
