It’s going to be pretty darn warm this week in San Diego County – so much so, that an excessive heat warning is in effect in our desert regions through the weekend. Here’s what you can expect at the coast and inland, too.

NBC 7 meteorologist Sheena Parveen said the warm-up had officially mid-week – and the hottest day would be Thursday.

“It’s going to be a warm one,” she said, adding that the coast could expect to see temperatures around 84 degrees and inland, a hot 97. "That's unseasonably warm."

San Diego County deserts will see temps around 115 degrees, Parveen said.

The National Weather Service in San Diego said the temps will be “above seasonal 30-year averages.”

We often hear about "heat waves" in San Diego County but what, exactly, defines this weather pattern? NBC 7 meteorologist Dagmar Midcap explains.

To that end, the NWS issued an excessive heat warning for the deserts, in effect from 10 a.m. Wednesday through Sunday.

Extreme heat like this increases the risk for heat-related illness. It’s important to drink plenty of water, stay out of the sun, and leave strenuous activities for the early morning or evening, once it cools down a bit.

Some San Diego County facilities will serve as Cool Zones during warm-ups. Here’s a list of San Diego’s open Cool Zones.

Oof, it is HOT out there, San Diego. NBC 7 meteorologist Sheena Parveen shares safety tips on how to beat the heat during these heat waves in San Diego County.

Parveen said the heat will last into the weekend – although the temps will slightly trend down. So, lots of beach weather in San Diego's forecast on this final weekend of August 2021.

"Do NOT forget the sunblock," she added.

And next week, more warm weather, but not quite as hot as this week.

“Don’t expect a cool-down anytime soon,” she added.

Parveen said patchy haze is possible Thursday, too, from smoke from the wildfires burning in other parts of California.
