Los Angeles, Calif. – A blanket of low gray clouds hovers over the Los Angeles Basin early Monday, hinting at the city’s next round of coastal fog and calm, warm afternoons. It’s a classic Southern California fall setup — patchy morning haze giving way to sunshine and highs well into the upper 70s and low 80s. But for commuters and early travelers, the fog will be the biggest story to start the week.
According to the National Weather Service in Oxnard, patchy fog will develop late Monday and Tuesday mornings, especially along the I-10 and I-5 corridors from downtown L.A. through Pasadena and into the San Gabriel Valley. Visibility may briefly dip below one mile in some valley and coastal pockets before skies clear by late morning. Drivers should slow down, use low beams, and allow extra time on the morning commute.
Once the fog lifts, sunshine takes control through Wednesday, bringing warm, dry afternoons and calm breezes. Temperatures will range from the upper 70s inland to near 70°F along the beaches — ideal for outdoor work and early Halloween decorating. The marine layer rebuilds slightly midweek, bringing another round of light morning fog before fading toward the weekend.
Looking ahead, forecasters expect mild, steady conditions through Saturday, with no rain on the horizon. Cooler, more unsettled weather may approach by late Sunday as Pacific systems organize offshore — a reminder that fall’s tranquil stretch across Southern California rarely lasts long before the next pattern shift.
