Los Angeles Hits 90-degrees in 17 Days

Record heat returns to Southern California after fall-like conditions last month

The National Weather Service reported Monday that a heatwave had gripped the greater Los Angeles area Friday into early Saturday. Temperatures have topped 90 degrees in Riverside County for 17 days straight, and reached 102 degrees in Pasadena Friday morning.

The heat wave is part of a much broader phenomenon: Southern California has endured record-breaking heat this year.

“We’ve seen a lot of this type of weather here in the past month or so after the warm temperatures of the past few months,” said meteorologist Michael Koven, a meteorologist with the National Weather Service. “This is the most extreme heat [this year] since the 1970s.”

The heat wave’s intensity is unprecedented, said Koven, whose record for the most consecutive days with temperatures at or above 90 degrees is 16.

There have been many heat records this year, with most reaching the 90-degree mark:

• Heat wave in 2015. L.A. had a record 30 consecutive days with temperatures at or above 90 degrees from July 3 through Aug. 23, according to the Weather Service.

• Heat wave in 1986. L.A. had a record 32 consecutive days with temperatures at or above 90 degrees from Aug. 26 to Sept. 21, according to the Weather Service.

• Heat wave in 1954. Los Angeles had a record 28 consecutive days with temperatures at or above 90 degrees from Aug. 3 to Sept. 29, according to the Weather Service.

The heat wave was the result of the El Nino effect, or the ocean warming off the coast. “It’s a very unusual situation,” said meteorologist Tom Wickwire, a meteorologist with the Weather Service.

“The ocean is warming up along the entire U.S. coast,” he said. “It’s bringing the ocean temperatures back up to the average temperature that we
