Hot temperatures are set to surge across San Diego County starting Thursday morning, reaching 15–20 degrees above normal, according to the National Weather Service.
On Wednesday, we have warm and sunny weather with highs in the upper 60s to low/mid 70s from the beaches to the valleys. Offshore winds will gust 15–25 mph in the mountain communities.

From Thursday 10 a.m. to Friday 8 p.m., the county is under a moderate heat advisory from the coast to the foothills.
