San Diego's Weather Forecast for August 25, 2022: Slight cooling trend into weekend

Posted
and last updated

Our local mountains and deserts are under a Flash Flood Watch until 10P and for the southeastern pocket of our county, a Flash Flood Warning is in effect until 7P.

Activity isn't as widespread as yesterday but we're still dealing with severe thunderstorm cells passing through our mountain communities, including Mt. Laguna, that has resulted in lightning and heavy rain.

Activity diminishes towards sunset and chances for monsoon thunderstorms on Friday afternoon are low.

A trough building off British Columbia will slowly dig southward, and this will bring relief in terms of daytime highs and lower humidity as we head into the weekend. The marine layer will gradually deepen each morning towards inland communities, and temperatures across our microclimates will trend below or near average by Sunday thanks to the increase of onshore flow.

The cooldown, however, is short-lived. Warm temperatures rebound early next week.

If you're headed to the beaches, we have a south swell moving in that'll bring in 4-6' sets and the rip current risk remains high. It's highly advised you swim near a lifeguard tower, especially if you're an inexperienced swimmer.

Friday's Highs:
Coast: 74-80°
Inland: 83-93°
Mountains: 80-95°
Deserts: 102-107°
