Yosemite National Park officially opened its 2026 fire season today, warning that warm, breezy weather is already drying out vegetation across the valley and the high country. Park staff say the early-season designation is meant as a reality check: small lapses in judgment, such as leaving a campfire unattended, flicking a cigarette butt, or parking a hot vehicle over dry grass, can trigger a blaze that races through cured fuels.
Park officials rolled out the declaration with a plea for extra caution as conditions continue to dry. Formal fire restrictions are not yet in place but could tighten as summer heats up, according to Active NorCal. The outlet reports that afternoon thunderstorms in the high country, combined with rising visitor traffic, are adding to the fire risk this season.
Park rules and what’s allowed
Campfires are allowed only in designated fire rings and barbecue grills, and portable stoves that burn gas, liquid fuel, or propane are still permitted, even if tighter restrictions arrive later, according to Yosemite National Park. Smoking is restricted to designated areas, is generally off-limits on trails, and is banned within 25 feet of buildings. Fireworks are never allowed in the park.
How to avoid accidental ignitions
Campers are urged to use the douse, stir, and feel method to make sure every ember is completely cold to the touch before leaving a fire, and to avoid parking vehicles on dry grass, since hot exhaust systems and catalytic converters can ignite vegetation, as reported by Active NorCal. If you see smoke that does not appear to be part of a prescribed burn, officials say to call 911 and report the location, an estimated size, and the color of the smoke.
Why officials are watching conditions
Federal outlooks are calling for above-normal significant wildland fire potential across parts of northern California in June and July, following an unusually early snowmelt and a very warm, dry spring. That pattern raises early-season concerns for Yosemite, according to Drought.gov. The broader forecast is one reason park and regional managers are staging resources now and reminding visitors that rules and restrictions can tighten quickly if conditions deteriorate.
Before you go
Visitors are urged to check current conditions, fire restrictions, and any closures before heading to the park and to sign up for Yosemite alerts. The park posts its most up-to-date information on its official conditions page, according to Yosemite National Park. Drivers are also encouraged to slow down when pulling off the road, carry extra water, and treat every open flame or discarded ember as a potential ignition source throughout the summer.
