San Diego, CA – A stretch of mostly cloudy skies and mild temperatures continues across San Diego County this weekend, with patchy fog expected to return late Monday night into Tuesday morning. The cooler nights and low clouds could slow morning commutes and reduce visibility along coastal highways, including I-5 and I-805.
According to the National Weather Service in San Diego, highs will remain steady in the low to mid-70s through early next week. Overnight lows will dip into the lower 60s, with calm winds becoming light onshore breezes by afternoon. The agency notes patchy fog may form late Monday and linger into Tuesday morning, particularly west of I-15. Drivers should anticipate sudden drops in visibility near the coast and valleys.
The weekend will feature mostly sunny afternoons, offering good conditions for outdoor events. Saturday and Sunday highs will hover near 74°F, though nights will cool quickly under partly cloudy skies. By Monday, skies will clear in the afternoon before fog redevelops overnight.
Travelers are advised to use headlights in fog-prone areas and allow extra time during morning drives. Residents should also plan for cooler evenings, especially in inland neighborhoods. Coastal visitors should be prepared for shifting conditions, as visibility may vary significantly between beach areas and nearby freeways.
