Dense Fog and Low Visibility

Significant fog is expected to blanket portions of San Diego County, particularly coastal areas, leading to reduced visibility and impacting commutes and outdoor activities. The San Diego fog is anticipated to be thickest during the morning and evening hours, potentially causing significant disruptions. This San Diego fog advisory means drivers need to exercise extra caution.

• Reduced visibility in coastal areas: Expect visibility to drop to less than a quarter-mile in many coastal communities, making driving hazardous.
• Potential delays on freeways and roadways: Expect significant delays, especially during peak commuting hours, on freeways like the I-5, I-805, and I-15, as well as surface streets. San Diego traffic will likely be heavier than usual.
• Increased risk of accidents: Low visibility dramatically increases the risk of traffic accidents. Drive defensively and be aware of your surroundings.
• Recommendations for safe driving in foggy conditions: Reduce your speed significantly, increase your following distance, use your headlights (low beams are best in fog), and avoid using cruise control. If visibility is severely impaired, pull over to a safe location and wait for conditions to improve.
