San Diego mornings will test drivers this week as patchy fog and low clouds linger across Southern California, especially during Tuesday’s commute. Reduced visibility could slow traffic along major routes, including Interstate 5 and Interstate 8. Motorists should allow extra travel time during early morning hours and keep headlights on when fog thickens.
According to the National Weather Service in San Diego, patchy fog is likely to return late tonight into Tuesday morning. Clouds are expected to blanket the region before gradual clearing by midday Tuesday. Winds from the west may reach 10 to 15 mph, with gusts up to 20 mph, creating breezy conditions near the coast.
Residents across Chula Vista, National City, and Mission Valley may wake to gray skies, but sunshine should break through by afternoon. Inland areas like El Cajon and Escondido will also see cooler mornings, with highs topping out in the mid-70s through midweek. Coastal highs will hover near the low 70s, while evening lows settle into the mid-60s.
The cloud pattern is expected to repeat nightly through Thursday, followed by gradual clearing into the weekend. This early taste of fall weather will keep temperatures mild but may frustrate beachgoers hoping for sunny mornings.
Drivers should remain alert on coastal freeways during the morning rush, as fog and low visibility can change quickly. Morning cloud cover will be most noticeable through Wednesday, with drier, clearer conditions expected by late week.
