Dense Fog Blankets San Diego County

San Diego fog is a familiar phenomenon, but the current blanket of coastal fog is particularly dense. Visibility is significantly reduced in many areas, impacting morning commutes and travel plans across the county. This San Diego fog advisory is in effect for several hours.

• Areas with the densest fog: Coastal areas such as La Jolla, Del Mar, and Carlsbad are experiencing the most significant fog. Inland areas are seeing some fog, but with much better visibility.
• Expected duration of the fog: The fog is expected to persist through the morning hours, gradually lifting by late morning or early afternoon as the sun burns through. However, it may linger in low-lying coastal areas longer.
• Impact on morning commutes and travel: Expect significant delays during your morning commute. Allow extra time for travel and exercise caution. Reduced visibility presents a significant safety hazard.
• Safety tips for driving in foggy conditions: Reduce speed, increase following distance, use low-beam headlights (high beams reflect off the fog), and avoid sudden braking or lane changes.
• When to expect fog to lift: The fog is anticipated to dissipate by midday, though localized areas may remain foggy until the afternoon. Check your local San Diego weather forecast for specific updates for your area.
