Summer (21 June to 22 September)

  • Average Highs : 81 to 89ºF / 27 to 32ºC
  • Average Lows : 51 to 57ºF / 11 to 14ºC

Summer is by far the most popular time of year to visit Yosemite, mostly because it coincides with school vacations in the United States.

During the summer months (June to early September), most trails and roads are open so the majority of the park is accessible to visitors.

It is usually warm or hot, with occasional thunderstorms in the afternoon. However, summer is the traditional start of wildfire season in the Sierra Nevada, so smoke, fires, and evacuations are all possible.

Fall (23 September to 20 December)

Yosemite National Park - Fall
  • Average Highs : 56 to 83ºF / 13 to 28ºC
  • Average Lows : 33 to 51ºF / 0 to 11ºC

Fall (late September to November) is the best if you want to see the majority of the park, but substantially fewer people.

Unless there’s an excessively large snowstorm, the majority of the park remains open through October, however, there are no services along Tioga Road after September. In the fall, waterfall levels can be quite low, but the fall colors of the region’s deciduous trees are stunning.

Winter (21 December to 19 March)

Skiing in Yosemite
  • Average Highs : 46 to 51ºF / 8 to 11ºC
  • Average Lows : 28 to 30ºF / -2 to 0ºC

For ample solitude in Yosemite, winter (December to March) is the best season.

That being said, Tioga Pass and Glacier Point are inaccessible by car during the winter and tire chains are often required to get to Yosemite Valley and Wawona.

While the weather might be cold and snowy, the crowds are few and far between, making for excellent skiing and snowshoeing conditions. The winter months are truly a magical time to visit Yosemite if you come prepared with the proper clothing, like heated gloves, winter boots, and winter sleeping bags.

Spring (20 March to 20 June)

Yosemite National Park - Spring
  • Average Highs : 57 to 71ºF / 14 to 21ºC
  • Average Lows : 34 to 45 / 1 to 7ºC

In general, crowds during the spring are much more manageable, especially when compared to the summer.

However, the weather is very variable and winter storms are not out of the ordinary. Additionally, Tioga Road and Glacier Point Road can remain closed until June due to the snow, which limits the places you can visit during the spring. 

Anyone heading into Yosemite at this time should have tire chains and should know how to use them.
