Temperature records were broken across San Diego County on Friday during a sizzling mini heatwave, but cooler weather is forecast for the weekend.
The record highs were 102 in Escondido, 97 in Chula Vista, 96 in Vista, 95 in San Diego and 84 at Oceanside Harbor. El Cajon’s record high of 99 was tied.
But it will be as much as 20 degrees cooler by Sunday as winds shift to the southwest off the ocean.
“It will be significantly cooler west of the mountains today as onshore winds strengthen and the ridge aloft weakens. Lower desert heat will continue today,” the weather service said.
Highs on Saturday will be 72 to 77 near the coast, 80 inland, 81 to 86 in the inland valleys, 76 to 84 in the mountains and 99 to 104 in the deserts.
Meteorologists said it will be even cooler by early next week.
“What a temperature roller coaster,” the weather service said. “After this recent heatwave, we will be bringing jackets back out Monday-Tuesday as temperatures fall below average by some 5-10 degrees west of the mountains and by 10-15 degrees over the mountains and deserts.”
