Fall Heat Wave Sends San Diego County Temperatures Soaring

NBC Universal, Inc.

A fall heat wave is gripping San Diego county this week with most areas under either a heat advisory or warning as temperatures rise into summer-like territory five to 15 degrees above average for this time of year.

Thanks to a bit of high pressure, an offshore flow is warming San Diego County with a heat advisory for the coast and inland valleys through 8 p.m. Wednesday and an excessive heat warning for the deserts until 11 p.m. Tuesday.

Temperatures are expected to peak on Tuesday and be in the mid-80s at the coast and the mid-90s inland. The mountains will see temperatures near 90 degrees and the deserts could reach 110 degrees, NBC 7 Meteorologist Sheena Parveen said.

As another heat wave grips San Diego County, NBC 7’s Joe Little checks in with folks in Ocotillo Wells.

From Tuesday's peak, temperatures will gradually cool into the weekend as cooler airmass returns. It may even feel fall-like, Parveen said.

“It’s going to be unseasonably warm across the whole county,” NBC 7 Meteorologist Sheena Parveen said. “But the good news is as we head into the weekend, we’ll start to cool down a little bit.”

To avoid any heat-related illness, it’s best practice to stay hydrated with water, limit outdoor activities, wear loose, light clothing and to stay indoors in cool spaces.

The county has opened several cool zones for residents to escape the heat. Find locations near you here.

Depending on who you ask, the heat is a good thing, NBC 7's Brooke Martell reports.
