California Wildfires 2026: Fire Updates, Smoke Safety & Power Backup Guide

California wildfires 2026: statewide snapshot

Statewide statistics help show the scale of a fire season, but they do not describe the immediate risk in one neighborhood. A relatively small wind-driven fire near homes can demand faster action than a much larger incident burning in a remote area.

CAL FIRE identifies statewide incident and damage figures as preliminary. Totals may change as new fires are reported, mapping improves and damage inspections are completed.

Major active California fires on July 17, 2026

The following table is a dated snapshot of larger incidents displayed by CAL FIRE when this article was updated. Acreage and containment can change several times in one day. An incident that is not listed here may still be important to your community.

Are California wildfires worse in 2026?

Not by statewide year-to-date acreage as of mid-July. California had recorded fewer fires and fewer burned acres than both the comparable 2025 period and the five-year average. That is useful context, but it is not a forecast for August, September or October.

CAL FIRE's 2026 seasonal outlook indicates that fire potential is expected to increase as summer progresses. The National Interagency Coordination Center also identified above-normal significant fire potential in parts of northeastern California during July.

Several conditions can turn a quieter first half of the year into a difficult late season:

• Vegetation continues losing moisture during prolonged summer heat.
• Dry grass can carry fire rapidly between shrubs, trees and structures.
• Low humidity can make vegetation easier to ignite.
• Strong winds can carry embers well ahead of the visible flame front.
• Lightning can start multiple incidents during the same operational period.
• Smoke from distant fires can affect communities that face no direct flame threat.

Where to find reliable California fire information

During a fast-moving incident, different sources answer different questions. No single map should be used for every decision.

Social media can provide eyewitness information, but posts may be old, mislocated or missing context. Verify urgent claims against an official agency update before changing routes or returning to an evacuated area.

A better way to prepare: watch three wildfire clocks

Most wildfire guides focus on the flame front alone. A household may, however, be affected by smoke or electricity loss before it faces a direct evacuation threat. Treat these as three separate clocks.

1. The fire clock

This measures how quickly the incident, evacuation zones and road closures are changing. Wind-driven fires can reduce decision time quickly. Your response should be based on official warnings and orders, not on how close the flames appear from your home.

2. The smoke clock

Smoke can arrive hours before a nearby fire, remain after flames move away or travel from a distant incident. The smoke clock determines when to close windows, run a portable air cleaner, reduce outdoor activity and relocate someone with elevated health risk.

3. The power clock

Electricity may fail because equipment is damaged, demand is disrupted or a utility initiates a Public Safety Power Shutoff. The power clock determines how long refrigerated food, communications, lighting, air cleaning and medical devices can operate.

What to do during an evacuation warning or order

California counties commonly use terms such as “Evacuation Warning” and “Evacuation Order,” although wording and zone systems can vary. Read the entire local notice rather than relying only on a color or map boundary.

Your 15-minute evacuation sequence

1. Confirm the order and zone. Read the newest official alert and identify the instructed route, closure or shelter information.
2. Gather every person and pet. Account for children, older adults, neighbors who depend on you and animals that may hide when stressed.
3. Take the prepared go bags. Prioritize medication, identification, water, communication devices, pet supplies and mobility aids.
4. Disconnect only what is safe and immediate. Do not spend evacuation time shutting down nonessential equipment or moving outdoor furniture.
5. Leave using the official route. Keep windows closed, use vehicle air recirculation if smoke is present and avoid roads reserved for emergency crews.
6. Check in from a safe location. Tell your out-of-area contact that you have left and where you are going.

People who should consider leaving during a warning

Leaving early may be safer when a household includes:

• Someone who uses oxygen, a powered medical device or refrigerated medication.
• A person who cannot tolerate smoke exposure.
• Older adults or children who need additional travel time.
• Someone who uses a wheelchair or other mobility equipment.
• Large animals, multiple pets or animals that are difficult to load.
• A household with only one narrow or congestion-prone exit route.

CAL FIRE provides additional evacuation preparation through its Get Set and Get Ready to Go resources.

Wildfire smoke safety: what the AQI means at home

Wildfire smoke contains fine particles that can travel deep into the lungs. You do not need to see flames—or even smell smoke strongly—for air quality to become unhealthy.

Check the current Air Quality Index before outdoor exercise, opening windows or deciding whether a household member should relocate.

How to create a cleaner-air room

• Choose a room with few windows and exterior doors.
• Close windows and doors without blocking an evacuation exit.
• Run a correctly sized portable HEPA air cleaner continuously.
• Set central HVAC to recirculate if the system supports that setting.
• Avoid candles, smoking, frying and activities that create indoor particles.
• Check and replace filters according to the equipment instructions.
• Keep medication, water, phone chargers and masks in the room.

A well-fitting N95 or P100 respirator can reduce particle exposure when you must go outdoors. Cloth face coverings and loose disposable masks do not provide the same level of filtration for wildfire particles.

For health guidance, review the CDC wildfire safety recommendations and the AirNow Fire and Smoke Map.

California wildfire power outages and PSPS events

Electricity may be interrupted by fire damage, damaged transmission equipment, emergency repairs or a Public Safety Power Shutoff. During a PSPS, a utility temporarily de-energizes selected lines when weather and vegetation conditions create a heightened wildfire risk.

Factors considered by utilities can include strong winds, low humidity, dry vegetation, observed damage and field conditions. A shutoff may affect a location that is not under an evacuation warning.

Southern California Edison explains its process on the official PSPS information page. Residents should also check the outage and notification pages of their own electricity provider.

What to do in the first 10 minutes of an outage

1. Confirm whether evacuation instructions have changed. A wildfire-related outage may occur at the same time as road or zone updates.
2. Preserve phone power. Lower screen brightness, close unneeded apps and use text messages instead of long calls when networks are congested.
3. Keep refrigerator and freezer doors closed. Do not repeatedly open the door to check the temperature.
4. Connect only essential loads. Prioritize medical equipment, communications, air cleaning and refrigeration before comfort appliances.
5. Check on household members and nearby neighbors. Confirm whether anyone depends on powered mobility or medical equipment.

Food safety during an outage

These time windows are general guidance, not a substitute for checking actual food temperature. When in doubt, discard food that may have been held at an unsafe temperature.

How to calculate a wildfire outage power budget

A portable power station should be sized around essential loads, not every appliance in the house. Start with the devices that protect health, communication, food and visibility.

Step 1: list the devices that must keep running

A practical priority order is:

1. Powered medical equipment and refrigerated medicine.
2. Phones, emergency radios and internet equipment.
3. A portable HEPA air cleaner for one cleaner-air room.
4. Refrigeration for food or medication.
5. Efficient lighting.
6. Fans or other limited comfort loads if capacity remains.

Step 2: calculate energy instead of looking only at watts

Watts describe how much power a device needs at one moment. Watt-hours estimate how much energy it uses over time.

Required watt-hours = device watts × hours of operation

For example, an 80-watt air cleaner running for 10 hours requires about 800 watt-hours before conversion losses and reserve capacity are added.

Step 3: add conversion loss and a reserve

Battery capacity is not identical to usable AC energy. This article uses a 90% planning efficiency for UDPOWER runtime estimates:

Estimated runtime = battery capacity × 0.90 ÷ average load

For wildfire planning, avoid designing a system that reaches zero percent under ideal assumptions. Retain a reserve for changing conditions, startup surges, colder temperatures and unexpected delays.

Can solar panels recharge a power station during a wildfire?

Solar charging may extend backup time during a multi-day outage, but it should not be the only charging plan. Smoke, ash, clouds, shorter daylight hours and poor panel orientation can sharply reduce solar input.

Use solar charging as one layer of a backup plan:

• Fully charge the power station before severe fire weather arrives.
• Test the panel, cable and input connection before an emergency.
• Place panels in direct sunlight only when outdoor conditions are safe.
• Keep connectors dry and protect cables from vehicles and foot traffic.
• Watch actual input wattage rather than assuming rated panel output.
• Stop using outdoor equipment when evacuation instructions change.

A practical 72-hour California wildfire kit

A wildfire kit should be divided into three groups: items that leave with you, items that support a home outage and items that stay in the vehicle. This prevents critical documents and medication from being buried under bulky supplies.

CAL FIRE's emergency supply guidance recommends preparing nonperishable food, water, medication, maps, documents, first-aid supplies, lighting, communication equipment and pet supplies. Review the complete Ready for Wildfire emergency supply kit.

What to complete before the next Red Flag Warning

• Enroll every adult phone in county emergency alerts.
• Write down the evacuation zone name or number.
• Drive two evacuation routes during normal conditions.
• Identify a meeting point outside the neighborhood.
• Choose an out-of-area family contact.
• Keep the vehicle above half a tank or maintain an adequate EV charge.
• Photograph important rooms and property for insurance records.
• Store documents in a protected physical and digital location.
• Test smoke alarms, carbon-monoxide alarms and fire extinguishers.
• Measure the real power consumption of critical appliances.
• Charge and test backup batteries at regular intervals.
• Confirm that pets can be loaded quickly into carriers or vehicles.
• Discuss early evacuation needs with older adults and disabled household members.

Returning home after a California wildfire

Return only after the responsible agency has reopened the area. A change in visible smoke or flame activity does not mean roads, utilities and structures are safe.

Before entering the property

• Follow road closures and law-enforcement instructions.
• Watch for unstable trees, damaged poles, downed lines and hot spots.
• Do not touch fallen electrical equipment.
• Keep children and pets away from ash and debris.
• Use protective footwear, gloves and respiratory protection appropriate for the conditions.

Before using electrical equipment

• Inspect cords, plugs and devices for heat, water or impact damage.
• Do not recharge a damaged battery or power station.
• Allow equipment exposed to moisture to be inspected before use.
• Do not energize household wiring that may have been damaged.
• Use a qualified electrician when the electrical system's condition is uncertain.

Document damage before cleanup

Take wide photos, close-up photos and video before moving damaged items when it is safe to do so. Save receipts for temporary lodging, emergency supplies, cleanup and replacement purchases. Follow the documentation process provided by your insurer or assistance program.
