SAN DIEGO, CA – Early fog drifts across Mission Bay and the downtown skyline this Monday morning, softening the city’s coastal glow under a still, gray canopy. But by midmorning, the haze will lift quickly, giving way to full sunshine and a stretch of classic Southern California warmth that will last well into the week.
According to the National Weather Service in San Diego, patchy fog will linger through about 9 a.m. before skies turn clear and dry across San Diego County. Highs will climb near 74°F today and surge into the low 80s by Tuesday and Wednesday as light winds shift offshore. That subtle change in direction will help warm inland valleys and foothills while keeping coastal neighborhoods pleasantly mild.
No rain is in sight through Friday, and humidity levels remain moderate—ideal for outdoor work, school sports, and Halloween preparations. The only morning hazard may be brief fog patches along I-5 and the Coronado Bridge during the early commute hours Monday and again late Wednesday night.
By midweek, sunshine dominates from the beaches to the mountains, with highs peaking around 85°F Wednesday afternoon. Slight cooling returns by Friday as ocean breezes rebuild, setting up a comfortable Halloween evening with mostly clear skies and mild 70s through sunset.
For now, it’s a golden run of late-October perfection—but models hint that a chilly November ahead may finally bring the first taste of coastal fall to Southern California next week.
