Wildfire Season Outlook: What Experts Want California Homeowners to Know

By Stephen Bennett and the Mercury Team

Wildfire season is no longer confined to just summer and fall. “Shifts in climate, prolonged drought, and evolving weather patterns are pushing fire season earlier, which means homeowners—especially in California—need to start paying attention much sooner each year,” notes Steve Bennett, Sr. Director, Climate Science and Catastrophe.

But being prepared for these events can help homeowners prepare for the California wildfire season in advance. Recent national fire data offers a wildfire outlook for the months ahead.

California Fire Season: What the Latest Wildfire Outlook Shows

California experienced relatively quiet fire activity early in 2026, but according to the National Interagency Fire Center’s outlook, after a warmer, drier-than-average January, both Northern and Southern California are seeing conditions that could set the stage for a more active fire season later this year. Forecasts through May do show near-normal fire potential, but experts caution that low snowpack levels and offshore wind events could change that picture quickly.

How the National Fire Outlook Applies to California

While national fire activity has remained low so far this year, the broader U.S. weather pattern, driven by a weakening La Niña, suggests that warm, dry conditions are favored across much of the West into spring.

February through May fire outlook trends

Northern California’s significant fire potential remains near normal through early spring, but unseasonably dry fuels and reduced snowpack can be early warning signs. In the south, ongoing warmth and a spring drying trend typically lead to more cured grasses and fine fuels by late April and May, which can support an uptick in fastmoving grass fires. The most active period is likely to coincide with the curing of these fine fuels, especially if March storms underperform and leave foothills and grasslands drier than average.

Snowpack and drought conditions in California

Across California, Sierra Nevada snowpack is currently running around 60–70% of average for this point in the season, with Northern Sierra basins closer to the mid-40% range and Southern Sierra basins near 90%. That’s enough to support short-term water supply stability—especially with reservoirs above normal—but not enough on its own to substantially lower longer-term fire potential. California is currently droughtfree, yet the state remains highly sensitive to weather swings, and relatively low snow reserves may lead to quicker spring drying in foothill and grassland areas.

Temperature and precipitation forecast impacts

Forecasters expect above-normal temperatures and below-normal precipitation in California through spring. These patterns not only promote earlier snowmelt but also accelerate the drying of grasses, shrubs, and other fine fuels. This could set the stage for rapid fire spread when offshore wind events or other fire weather conditions occur.

Key Risk Factors Homeowners Should Watch This Season

While early spring may bring only modest threat levels, several key environmental drivers could quickly elevate wildfire risk as the season progresses.

Drought and dry fuels

A combination of below-normal precipitation and rapidly drying vegetation can make dead fuels and grasses more flammable by late spring. This pattern could accelerate fire starts once seasonal winds pick up.

Offshore wind events

Offshore wind events—such as Santa Ana and Diablo winds—can rapidly intensify small fires and push flames toward populated areas, underscoring the importance of early defensible space maintenance before these wind events occur.

Early grass curing and fine fuels

Fine grasses that sprouted after early winter rain are already beginning to cure across portions of the state. Once dry, these light fuels can ignite easily and act as fast-moving carriers for larger fires.

How to Prepare Your Home Before Peak Fire Season

California’s peak fire season brings heightened risk, but preparation can greatly improve your home’s defense and your family’s fire safety. Here are a few things that should be on your home’s readiness checklist:

• Create defensible space: Clear leaves, dry grass, and debris within at least 100 feet of your home. Trim trees and shrubs to prevent fire spread.
• Harden your home: Install ember-resistant vents, seal gaps around eaves and decks, and use fire-resistant roofing or siding materials.
• Clean gutters and roofs: Remove pine needles and other flammable debris regularly.
• Prepare emergency supplies: Stock water, nonperishable food, medications, and N95 masks for smoke protection.
• Plan and practice evacuation routes: Know multiple exits from your neighborhood and establish a meeting place for family members.
• Stay informed: Sign up for local fire alerts and red flag warnings, and monitor air quality reports and evacuation notices.

Homeowners Insurance and Wildfire Preparedness

Wildfire risk also affects insurance availability and coverage terms. Be sure to review your homeowners policy limits and make sure your carrier participates in California’s FAIR plan if you’re in an elevated fire zone. Also, confirm replacement cost coverage, and document your belongings and property before peak season. Taking mitigation steps—like those outlined above—also may help demonstrate reduced risk in your specific area.

FAQs About California Wildfire Season

Is California’s fire season getting longer each year?

Yes. Warmer temperatures and prolonged dry periods have extended the fire season across much of the state, with active burning often beginning in late spring and continuing well into fall.

What causes wildfires?

Wildfires are caused by a combination of human activities and natural processes that ignite flammable fuels under hot, dry, and often windy conditions.

Does a wet winter reduce wildfire risk in summer?

Not necessarily. A wet winter can promote heavy grass growth, which later dries out and becomes additional fuel. The timing of rainfall and temperature patterns matters more than total precipitation alone.

How can I stay informed about fire conditions in my area?

Local air quality alerts and the National Interagency Fire Center wildfire outlooks are reliable ways to stay informed. Homeowners can also sign up for local reverse-911 alerts and review daily fire potential maps issued by the National Weather Service.

How do wildfires start?

Wildfires start when an ignition source, such as lightning, power lines, machinery sparks, campfires, or discarded cigarettes, meets dry vegetation and enough heat and oxygen to sustain burning. In the United States, the majority of wildfires are the result of human activity and urban infrastructure rather than by natural initiation.
