The official temperature in downtown Los Angeles reached 92 degrees Sunday, a new record high for March 15, topping the 89 set in 1978.

Peaking a few minutes before 1 p.m., it was one of six record temperatures on Sunday in Los Angeles County.

The others included LAX’s 88, which surpassed the 83 of 1959; UCLA’s 91 that scorched the 83 of 1978; Long Beach’s 92 that beat the 86 heat in 1978; Burbank’s 90, which outpaced the 86 reached in 1994. Sandberg’s 77 tied the 77 it saw in 2013.

In Orange County, Santa Ana’s 92 broke the 89 total registered in 1931 and Newport Beach’s 85 overtook the 83 compiled in 1959.

The weekend heat wave was the result of a slow-moving high pressure system hovering over the Los Angeles Basin that drew dry, hot winds from inland deserts toward the sea, the National Weather Service said.

A cooling trend was expected to start Monday.

Thousands of runners on the streets of Los Angeles were given a slight break, with a deck of high clouds preventing direct sunlight from pushing temperatures beyond the high 70s and low 80s during the midmorning hours when bulk of the race was run.

On Saturday, records fell across the region.

The downtown L.A. high of 93 degrees on Saturday, hit just before 1 p.m., far surpassed the previous record of 88, set in 1951, the NWS said.

Other Los Angeles locales that set Saturday record temperatures were LAX at 90, topping the 86 mark of 1951 and UCLA at 92, way ahead of the 84 registered in 1994, the weather service said.

Long Beach’s Saturday afternoon high rose to a record 94, nine degrees beyond the previous record 85 also set in 1994, according to the NWS.

Saturday highs reached 93 in Torrance, and 96 in Fullerton, but the weather service doesn’t release record temperature statistics for those cities.

In Orange County, Santa Ana at 94 and Newport Beach at 85 experienced record Saturday highs, passing the 91 and 76 totals, respectively marked in 1926.

Those two cities also set records for the highest low temperature for March 14. In Santa Ana, Saturday’s overnight low of 65 exceeded the previous mark of 60 in 1993. In Newport Beach, the low of 63 rose above the 60 of 2003.
