Weather can vary with elevation. In the summer, daytime temperatures often exceed 100 degrees F in the foothills but seldom exceed 90 degrees F in the sequoia groves. Even in the summer, backpackers in the highcountry can encounter nighttime temperatures in the low 30's and occasionally even in the 20's.

In any season, it is wise to bring clothing that can be "layered". Always include some kind of rain gear.
