San Diego's Weather Forecast for September 8, 2024: Relief from the heat this week

Posted
and last updated

We're almost done dealing with the dangerous heat! But keep in mind, Monday will still be a scorcher.

The Heat Advisory at the coast will last until 8pm Monday, with high temperatures between 82 and 97 degrees.

The Excessive Heat Warning for the inland valleys continues until 8pm Monday, with highs well into the triple digits.

Don't expect much relief overnight, either. Sunrise temperatures will only dip into the 70s for most coast, inland, and mountain areas, while the deserts will only cool to the 80s and even some 90s.

Temperatures will remain above normal through Tuesday, but will be 10 to 20 degrees cooler than today. By Thursday, temperatures will top out 5 to 10 degrees below normal, which is 20 to nearly 35 degrees cooler than today!

This cooler and drier air moves in from a trough of low pressure developing over the west which will also usher in a return of the marine layer in the overnight and morning hours.

Monday's Highs: 
Coast: 82-97°
Inland: 100-111°
Mountains: 86-100°
Deserts: 103-110°
