SAN DIEGO – The coastline woke under a soft white haze early this morning, with headlights glowing faintly through the mist from La Jolla to El Cajon. A Dense Fog Advisory remains in effect until 9 a.m. PST, warning drivers of near-zero visibility in parts of San Diego County’s coastal mesas and western valleys.
According to the National Weather Service in San Diego, visibility may drop below a quarter-mile through 9 a.m., especially along I-5, I-8, and Highway 163. Commuters are urged to slow down, use low beams, and allow extra time for travel. The fog, lingering between 300 and 800 feet in elevation, will gradually lift by late morning as the sun warms the marine layer.
After the fog clears, the pattern turns tranquil. Skies become mostly sunny with afternoon highs in the low to mid-70s through Tuesday, ideal for outdoor activities or early holiday prep. Nights remain mild but humid, with patchy fog returning each morning along the coast and valleys.
Midweek, a slight breeze develops as inland temperatures inch higher. High pressure continues to dominate into late week, keeping the region dry and stable. The calm stretch marks a typical November weather transition, where cool coastal mornings meet pleasantly warm afternoons.
Looking ahead, long-range models hint at a potential cool-down late next weekend as weak Pacific energy brushes the coast. For now, it’s a classic Southern California setup — fog early, sunshine by lunch, and another round of fall calm across San Diego County.
