SAN DIEGO, Calif. – Early risers across coastal California may wake to patches of fog and damp roads Tuesday morning, but clearer skies and warmer afternoons are right behind. After a mild Columbus Day, temperatures will climb steadily through midweek as a dry and calm stretch of fall weather settles over San Diego County.
According to the National Weather Service in San Diego, low clouds will thicken late Monday into early Tuesday, with brief drizzle or light showers possible along I-5 and coastal neighborhoods before sunrise. Drivers heading to work or school should allow extra time and use low beams in fog-prone zones. Winds will remain light, shifting from southeast to southwest by afternoon as skies gradually brighten.
By Wednesday, a ridge of high pressure will bring abundant sunshine and highs in the upper 70s to near 80°F—ideal for mid-October outdoor plans, pumpkin patch visits, and leaf-viewing trips across Balboa Park and Mission Trails. Cooler coastal breezes will return late week, keeping daytime highs pleasant and evenings comfortably crisp.
Meteorologists say the region’s mild trend should hold through next weekend, with no major storm systems expected. Residents are encouraged to enjoy the fall calm before colder Pacific systems begin influencing Southern California later this month. Keep checking Caltrans updates if traveling I-8 or I-15 during early-morning fog events, which may briefly reduce visibility.
