SoCal Heat Wave Shatters Records Across Region: Here Are All Friday's Historic Highs

COACHELLA VALLEY, CA — As the day's grueling heat hit its peak late Friday afternoon throughout Southern California, temperature-measuring stations in towns across multiple counties began clocking historic high temps, according to the National Weather Service.

The sun came down especially hard on the Coachella Valley, where in the small towns of Palm Desert and Palm Springs, temps had reached 122 degrees by 3:30 p.m. — a full five degrees hotter than the old record.

Scroll down for a full list of Friday's record highs. We'll be updating it throughout the evening, so check back for the latest.

SoCal's second record-breaking heat wave of summer 2017 arrives just two weeks into the season. Another temperature surge broke records across the region two weekends ago, on the eve of Summer Solstice.

An "excessive heat warning" issued by federal weather officials was in effect for huge swaths of Southern California on Friday.

"A strong upper level high pressure system over the southwest United States along with locally breezy northerly winds at the surface will create dangerous record-breaking heat over much of the area through Saturday," weather officials warned. They said the "potentially life-threatening" heat would "also bring favorable conditions for fire growth."

Only the neighborhoods right up along the Pacific coastline were spared from the day's historically oppressive heat, thanks to a healthy sea breeze cooling them down, meteorologists said.

SoCal's latest heat wave is expected to last through Saturday evening.

Below are some of the heat records broken across the region on Friday, July 7, along with predicted highs for Saturday, July 8. All forecasts and historical data have been pulled from National Weather Service reports.

Just like summer's first heat wave, meteorologists are blaming this one on a weather pattern called “Four Corners High" — named for its epicenter at the famous intersection of Arizona, Utah, New Mexico and Colorado.

The high-pressure system is known to spread smothering heat as far up as NorCal and northern Nevada, as far east as central Texas and as far west as the Pacific coast.

Friday's heat surge set records not only across SoCal but in Phoenix, Arizona (118 degrees), and McCarran International Airport in Las Vegas, Nevada (116 degrees).
