Map Shows California Cities Break Heat Records Amid Soaring Temperatures


Multiple California cities have broken records for high temperatures amid a relentless summer heat wave.

Record-high temperatures were reached on Sunday in the Southern California desert cites of Palmdale and Lancaster, according to the Los Angeles office of the National Weather Service (NWS).

Palmdale Airport topped out at 114 degrees, beating a 1989 record of 110 degrees. At Lancaster’s Fox Airfield, the thermometer struck 115 degrees, also besting a previous high of 110 degrees recorded in 1989, as well as in 2017.

Both cities also broke all-time records for the most consecutive days above 110 degrees, with temperatures having been recorded in Lancaster since 1945 and Palmdale since 1931.

NWS Los Angeles said that the readings from Sunday were preliminary and the final temperatures could be even hotter in a post to X, formerly Twitter.

“Another record setting day,” the post reads. “Palmdale has reached 114 so far, breaking its daily record. Lancaster is up to 115, breaking its daily record, monthly record & all-time record. These temps are just preliminary, the official record may be hotter.”

Newsweek reached out for comment to NWS via email on Monday evening.

Temperatures were even hotter in Southern California’s Coachella Valley— about 120 miles southeast of Lancaster—where a record high of 124 degrees was seen in Palm Springs on Friday.

The California heat wave was not limited to the southern part of the state, with Northern California’s Redding and Ukiah also hitting record-high temperatures over the weekend.

An all-time high of 120 degrees was recorded at Harry Reid International Airport in Las Vegas, Nevada, on Sunday, while a daily high of 116 degrees was struck at Arizona’s Phoenix International Airport on Monday. The previous record high of 115 degrees was set in 1985, according to NWS Phoenix.

Around 73 million Americans, approximately one-fifth of the U.S. population, are under some type of heat advisory this week. Those living in Western states can expect the highest temperatures, with NWS issuing excessive heat warnings—temperatures of 105 or higher—in areas with more than 35 million residents.

Heat-related illnesses are responsible for at least 1,000 deaths per year, according to NWS. Children, elderly people, pregnant women and those with chronic medical conditions are particularly prone to falling ill under extreme heat.

“Check on older, sick, or frail people who may need help responding to the heat,” a heat wave tips page on the NWS website reads. “Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia. Keep your children, disabled adults, and pets safe during tumultuous heat waves.”

Symptoms of heat-related illnesses can include muscle cramps, sweating, headaches, nausea, confusion and loss of consciousness. Keeping well-hydrated, wearing loose clothing and having access to air conditioning can reduce the risk of illness, while those who are outdoors are also advised to take regular breaks in shaded areas.
