Temperature records shattered for third straight day in San Diego

For the third straight day, temperature records fell across San Diego County on Wednesday as the icky-sticky heat wave proved to be a bit stronger than expected.

The good news: temperatures are going to drop sharply on Thursday, and the Santa Ana winds will be gone.

“You’re really going to notice the difference at the coast,” said Jimmy Taeger,a forecaster at the National Weather Service. “The temperature was 97 (Wednesday) at San Diego International Airport. On Thursday, the high will be 82.”

The 98 degree reading at the airport broke the record for Oct. 25. The previous record of was 95, set in 1983.

Records fell in at least seven places on Wednesday, including El Cajon, which reported a high of 101, breaking the day’s record of 96, set in 1983. Ramona reached 99, breaking the day’s record of 95, set in 2003.

Vista also hit 99, breaking the day’s record of 94, set in 1983. Alpine climbed to 97, breaking the day’s record on 94, set in 1966. Chula Vista hit 98, breaking the day’s record of 93, set in 1983. And Escondido reached 102, breaking the day’s record of 97, set in 1909.

The temperature at Miramar MCAS hit 105 on Wednesday, which wasn’t a record. A day earlier, Miramar reached 108, which tied with San Luis Obispo for the highest temperature in the nation.

Santa Ana winds have been pushing hot, dry air all the way from the desert to the offshore waters. A weak sea breeze kicked in on Tuesday, pushing that hot air back onshore. A similar thing happened early Wednesday, helping to create record-setting temperatures.

The winds have died out, which is allowing the relative humidity to start rising to more normal levels across the county.

By Saturday, San Diego will return to weather it can boast about.
