Most intense heat wave of the year hits the Los Angeles area: what you need to know

A major heat wave hits southern California, bringing some of the hottest temperatures of the year starting Tuesday.

Here’s what you need to know:


The warmest conditions will come Tuesday and Wednesday, with gradual cooling on Thursday and through the weekend, said meteorologist David Sweet of the National Weather Service’s Oxnard office.

The weather service issued an excessive heat warning from 10 a.m. Tuesday to 9 p.m. Friday in the mountains of Ventura and Los Angeles counties, not including the Santa Monica Range.

Terms & Conditions

Scorching temperatures are expected in interior parts of Los Angeles County, with Santa Clarita and Woodland Hills likely to hit 109 degrees on Wednesday and Lancaster 111.

The coastline will also experience exceptionally warm conditions, with 86 degrees expected in Ventura and Malibu on Tuesday and 97 expected for Long Beach.

Some of the hottest temperatures are expected in low-desert areas, including the Coachella Valley and Borrego Springs, which could peak between 110 and 120 for the entire week.

Temperatures could break records and will reach around 10 to 20 degrees above what is typically seen at this time of year, said Alex Tardy, a meteorologist at the San Diego Weather Station.

Fire hazard

The winds are causing red flag conditions in southern Santa Barbara County, with gusts of 40 to 50 mph. And low humidity, high heat and unusually dry fuels create a high fire risk, the weather service said.

Extremely low humidity levels may have contributed to the outbreak of the 400-acre Flats fire in the Santa Rosa Mountains on Sunday morning. The blaze, which burned down at least two homes, continues to threaten several mountain communities southwest of Palm Desert in Riverside County.

A firefighter was injured in the blaze and officials fear the regional heat wave will complicate the fight to put it out.


To stay cool in the next few days, officials recommend the following:

  • Drink lots of fluids
  • Stay in air-conditioned rooms or in the shade as much as possible
  • Do not leave children or pets unattended in vehicles

Among other tips from the National Weather Service:

  • Check in with older relatives and neighbors.
  • Wear light, loose clothing.
  • Reschedule strenuous activities to cooler hours in the morning and evening.

Some general hours from county health officials:

  • Avoid the sun and stay in a cool indoor place from 10 a.m. to 3 p.m.
  • If you don’t have air conditioning or can’t afford to run it, take a cool shower twice a day and go to a cooling center or other air-conditioned location. Even a shady yard or park is better than staying indoors.
  • Stay very hydrated. In a heatwave, this means drinking two to four glasses of water every hour.
  • Avoid alcohol, reduce physical activity, and don’t exercise outdoors during the hottest hours of the day. If you must work out, be sure to drink juice or sports drinks to replenish the salts and minerals removed from your body when you sweat.
  • Wear loose, light-colored clothing and a hat if you are going outdoors.
  • Check your neighbors, friends and relatives, especially if they are elderly or do not have air conditioning.


Many Los Angeles County libraries, senior centers, and community spaces offer residents free respite from the heat. Helen Chavez, associate director of the county’s emergency management office, recommended people find a cooling center near them and call to make sure the times posted online are correct.

Most public pools in Los Angeles also open just in time for the heatwave, with availability from 2 p.m. to 6 p.m. Tuesday through Friday and from 1 p.m. to 5 p.m. Saturday and Sunday, the Parks and Recreation Department said. city.

From next week the pool hours will change, with weekday morning hours. A complete list of swimming pools, their addresses and hours of operation can be found on the website of the Ministry of Recreation and Parks.
