San Diego wakes up Sunday to patchy marine-layer low clouds and fog, with increasing mid- and high-level clouds, but the beach forecast is a much rougher story. A slight chance of morning showers gives way to increasing rain chances and an extensively cloudy afternoon with temperatures around or slightly below seasonal averages, while dangerous surf remains the bigger concern along the coast.
Morning Showers Give Way To Cooler Afternoon
Rain chances increase into the afternoon, with bands of light to moderate rain possible around the city. Northwest winds will run 5 to 10 mph, with gusts reaching 20 mph, as extensive cloud cover remains over the region and mid- to high-level clouds continue increasing.
The broader regional forecast calls for more persistent showers over the mountains and inland areas, where an isolated thunderstorm is possible Sunday afternoon. Coastal San Diego should see considerably less rain, with extensive cloud cover and temperatures around or slightly below seasonal averages for Sunday.
High Surf And Coastal Flooding Stay In Play
A High Surf Advisory and Coastal Flood Advisory remain in effect through 11 p.m. Tuesday, according to the National Weather Service. South- and southwest-facing beaches could see breaking waves of 6 to 10 feet, while west-facing beaches may see waves of 4 to 7 feet, along with strong rip and longshore currents.
The advisories also warn of tidal overflow and coastal flooding in low-lying areas, as well as beach erosion. Inexperienced swimmers should stay out of the water, and drivers should never go around barricades or through flooded areas of unknown depth.
High surf can contribute to flooding in coastal communities and beach erosion. Coastal flooding remains a concern in low-lying areas.
Drier Labor Day, Then A Gradual Cooldown
Labor Day is expected to bring drier, around-average conditions on Monday, with drier conditions returning Tuesday. Wednesday will be the warmest day, with inland highs returning to the low to mid-90s and afternoon showers and thunderstorms over mountains and adjacent deserts, followed by a gradual cooldown through the workweek.
