California heat wave pushes temps to 112°F as wildfire warnings expand
Southern California is in the grip of a dangerous heat wave this week, with temperatures expected to reach as high as 112 degrees Fahrenheit in some areas. The extreme conditions have triggered warnings about heat-related illness, elevated wildfire risk, and possible precautionary power outages for thousands of residents.
The National Weather Service has issued an extreme heat warning for much of the region through Friday. Forecasters say the hottest spots will be the inland valleys and the San Gabriel and Santa Monica mountains, where thermometers could hit 112 degrees. Even coastal areas are not spared, with possible triple-digit readings of up to 102 degrees in places away from the immediate shore.
Which areas are under extreme heat warnings?
In Orange County, extreme heat warnings are in effect until Friday for the Santa Ana Mountains, foothills, and inland cities including Santa Ana, Garden Grove, Anaheim, Fullerton, and Irvine. Coastal parts of Orange County are under a less severe heat advisory.
The National Weather Service said the next three days will be the peak of the heat event. Daytime highs will range from 100 to 106 degrees across valleys and lower mountain elevations, with the western San Fernando Valley potentially reaching 106 to 112 degrees.
Inland areas of coastal regions could warm into the 90s, with some readings of 100 to 101 degrees possible.
Why is the wildfire danger so high right now?
The heat is combining with gusty winds and very low humidity to create critical fire conditions. A red flag warning is in effect until Friday for the San Gabriel Mountains and the Golden State (5) and Antelope Valley (14) freeway corridors in northern Los Angeles County.
Temperatures in the red flag zones could reach 106 to 108 degrees, with humidity levels dropping below 10 percent in some areas. The Los Angeles County Fire Department said it is increasing staffing and pre-positioning personnel and resources across the region to respond quickly to any wildfires.
Fire officials also warned that elevated surf and strong rip currents are still affecting the coast, raising the risk of drowning as residents flock to beaches to escape the heat.
What are Public Safety Power Shutoffs?
Southern California Edison announced the possibility of Public Safety Power Shutoffs for about 3,100 customers in Los Angeles County. The affected areas are mainly near Malibu and the Santa Monica Mountains Recreational Area, plus northern areas such as Castaic and Sandberg.
These shutoffs are precautionary power cuts implemented during high fire danger to prevent blazes sparked by energized electrical lines and equipment.
Records falling across the region
Downtown Los Angeles set a record Monday by reaching 98 degrees, breaking the old mark of 96 set in 1931. Long Beach hit 97 degrees, topping the 2010 record of 95. In Orange County, Anaheim reached 98 degrees Monday, tying a record from 2010, while Santa Ana hit 100 degrees, matching the record set in 1969.
Forecasters said this is the warmest summer on record in downtown Los Angeles. The average temperature from July 1 through Monday was 88.4 degrees, surpassing the previous record of 88.1 set in 1886 and matched in 1998.
Where can residents find relief from the heat?
Health officials urge people to drink plenty of fluids, stay in air-conditioned rooms, avoid the sun during the hottest hours, and check on relatives and neighbors. They also stress never leaving children or pets in parked vehicles, even for a minute, as temperatures inside cars can become deadly quickly.
Many Southland cities operate cooling centers for residents without air conditioning. Los Angeles residents can find a list of available cooling centers here or call 311 for information. A countywide listing of cooling centers, pools, and splash pads is available at ready.lacounty.gov/heat.
Frequently asked questions about the California heat wave
How hot will it get in Southern California this week?
Temperatures could reach 112 degrees in the hottest inland areas like the San Fernando Valley. Coastal regions may see highs around 100 degrees, while beaches will be slightly cooler but still under heat warnings.
Why are power shutoffs happening during the heat wave?
Southern California Edison may cut power to about 3,100 customers to prevent wildfires. High winds and dry conditions can cause power lines to spark blazes, so utilities sometimes shut off electricity as a safety measure.
What should people do to stay safe in the extreme heat?
Stay hydrated, remain in air-conditioned spaces, avoid outdoor activity during peak heat hours, and never leave children or pets in parked cars. Cooling centers are available for those without AC.
