San Diego, Calif. – Coastal residents will wake to patchy fog Tuesday morning before sunshine returns by midday, keeping San Diego’s pattern of cloudy starts and bright afternoons alive through the week. Highs will hover in the upper 70s to low 80s, with nights staying mild in the upper 60s.
According to the National Weather Service, low clouds will thicken overnight before breaking up by late morning Tuesday. Patchy fog is most likely along coastal routes, including Interstate 5 and Highway 163, potentially slowing commutes. West winds around 10 mph will develop through the afternoon, keeping temperatures comfortable.
By midweek, clouds will continue to build overnight with breaks of sunshine each day. Thursday may start gray with early fog, but skies are expected to clear, reaching highs near 79 degrees. Inland valleys may see slightly warmer conditions compared to the coast.
Friday looks to be the warmest day of the week, with partly sunny skies and highs near 81, before a return of nightly cloud cover through the weekend. The marine layer is expected to persist, meaning San Diego residents should anticipate cooler mornings before warming afternoons.
Weather service officials advise motorists to allow extra travel time during foggy hours and to use headlights when visibility drops. More consistent sunshine is expected by early next week.
