Yosemite Valley, along with Wawona Meadow, lies at an elevation of 4,000 feet (1,200 meters). Only the Hetch Hetchy area is lower. The Glacier Point Road starts at an elevation of 6,000 feet (1,800 meters) and climbs from there, and the Tioga Road ranges from 6,000 to 10,000 feet (1,800 to 3,000 meters). So expect temperatures in most other areas of the park to be lower than they are in Yosemite Valley.
If you're driving in Yosemite in winter, you're required to carry tire chains in your car. Check the Yosemite Road Conditions page for more information.
