SAN DIEGO, Calif. – Drivers in San Diego could face patchy fog late Monday night into Tuesday morning, reducing visibility along I-5 and I-8. Commuters should allow extra travel time and use caution on coastal roads where conditions may change quickly.
According to the National Weather Service, fog may linger near the shoreline through mid-morning Tuesday before skies gradually clear. Temperatures will hold near seasonal averages, with daytime highs in the mid-70s and overnight lows dipping into the 60s. Light winds may shift southwest in the afternoons, creating slightly cooler evenings across San Diego County.
Neighborhoods along the coast, including Pacific Beach and La Jolla, are expected to see the thickest fog layers. Inland areas like El Cajon and Escondido will remain clearer but cooler at night. Drivers using coastal freeways, including I-5 near downtown and I-8 toward Mission Valley, should prepare for sudden visibility drops.
Residents are urged to use headlights in low-visibility areas, avoid speeding, and remain alert for slick road surfaces during foggy mornings. Public transit schedules may run smoothly, but local officials caution that heavier fog pockets could briefly delay bus and trolley routes.
Conditions improve by Wednesday, when October arrives with sunnier skies and highs in the upper 70s. The first week of the new month looks stable, with mild afternoons and cool nights continuing.
Warnings remain in effect for patchy fog along the coast through Tuesday night, with updates expected if conditions worsen.
