SoCal faces ‘dangerous’ heat wave — and what meteorologists are concerned about

A heat wave in Southern California this week is expected to shatter records — with temperatures set to surge 35 degrees above normal and into the triple digits.

The National Weather Service warned Monday that “a dangerous heat wave” will scorch the region this
week, with the mercury peaking Tuesday through Friday.

Temperatures will hit highs of the mid-90s across SoCal on Monday, before climbing to the low 100s by Wednesday, according to the weather service.

“Temperatures will continue to be warm overnight and may not provide much relief from heat stress,” NWS Los Angeles wrote on X, adding that many daily and potentially monthly March records would be broken.

The prolonged heat this early in the year poses concerning risks to residents, meteorologists warned.

“There will be a high risk for heat illness for everyone — especially in locations away from the coast. If you or someone you know is at risk for heat-related problems, please make cooling plans now for the rest of this week,” the NWS warned.

Typically, during March, Los Angeles and the larger coastal region see temperatures in the high 60s, rarely climbing into the 70s.

“This is earlier in the year, so our bodies in the area aren’t used to these high temperatures,” NWS meteorologist Rose Schoenfeld told ABC7.

“That time of year is significant, so we do have concerns that people who work outside, people without air conditioning, and those who are more vulnerable — including the very young and the elderly — could face heat-related issues.”

The NWS has advised residents to stay hydrated throughout the week and check in on neighbors and loved ones during the heat.

Officials recommend staying in air-conditioned spaces when possible and avoiding outdoor activities, especially between 10 a.m. and 5 p.m.

Experts also warn residents not to leave cars parked without shade for long periods and never to leave a person or pet inside a car without air conditioning, as temperatures can become deadly within minutes.

The public is also urged to recognize the signs of heat illness, including heat stroke and heat exhaustion.

This unusual heat cycle is being caused by a strong high-pressure system slowly sitting over the region, acting like a lid that traps heat and allows temperatures to build through the week.

Winds will stay light, with slight offshore flow in the mornings and weak onshore breezes in the afternoons, offering little cooling.
