Downtown Los Angeles woke up in a gray blur Sunday morning, March 29, 2026, as patchy fog settled in and dragged visibility down in coastal neighborhoods before the sun gets its turn. Morning lows hovered around 55°F, but the calm will not last long. Inland spots are headed for about 85°F this afternoon while the coast stays chilled in the 60s and low 70s. If you are driving from the beach to the valleys, prepare for a quick jump in temperature and adjust your layers on the fly.
Fog, Commute, and Flights
According to the National Weather Service Los Angeles/Oxnard, patchy fog is likely before 11 AM, with a moderate risk that some areas see dense fog cutting visibility to under a mile through Monday evening. Drivers using the 1, 101 and other coastal routes are urged to leave extra time and stick with low-beam headlights when the haze thickens. Low cloud ceilings in the early hours could also mean localized delays at area airports as flights work around the murky start.
Inland Heat, Cooler Coast
The weather story splits in two for Sunday. Inland neighborhoods and valley pockets are on track for the low to mid-80s, while beach communities and the immediate coastline stay much milder. This follows a recent run of unseasonably warm readings earlier in the month, although forecasters note that temperatures are not expected to get hot enough to trigger any official heat advisories.
Looking Ahead
A pattern change moves in by midweek. Highs cool back into the low to mid-70s from Tuesday, March 31, through Thursday, April 2, with gusty onshore winds and a slight chance of light rain Tuesday night into Wednesday. Gusty west to northwest winds are most likely Wednesday and Thursday along the coast, in the mountains and across the deserts, while weaker offshore breezes could return by Friday and Saturday. Air travelers should check for any flight impacts before heading out. For status updates, see Los Angeles World Airports.
Bottom line: think layers early and sunscreen late. A light jacket should cover you along the foggy coast, and anyone spending time inland will want water, shade and a plan for the afternoon heat. For hour-by-hour changes and any last-minute tweaks, check the National Weather Service forecast or your favorite weather app before you walk out the door.
