Check weather forecasts for areas you plan to visit before leaving home.
Temperatures and weather patterns can be drastically different throughout the parks at any given time. Tire chains may be required from early spring through late fall. Daytime temperatures can vary 20-30 degrees depending on your location. While shorts and sandals may be appropriate in the foothills in the spring and early summer, it may not be in the higher elevations where there may be several feet of snow on the ground.

Why do I have to use tire chains here?
Visitors heading into the mountains and sequoia groves of Sequoia and Kings Canyon National Parks and other areas of the parks and adjacent forest will likely be required to carry tire chains or cables due to snowfall/storms at any time between early fall through late spring/early summer. State law (CA Vehicle Code, Section 605, Sections 27450-27503) requires ALL vehicles (including 4-wheel/all-wheel drive) to carry tire chains or cables when entering chain-control areas.
Upon entering these chain-restricted areas, visitors need to have proper fitting chains in good repair. Ensure that chains fit and practice installing them prior to entering the parks. Weather and chain control designations can change rapidly, often multiple times per day.
Be prepared! Avoid the disappointment and delays associated with being turned away upon arrival.
