Current Conditions: Foggy Start to the Day

San Diego is waking up to a blanket of fog, significantly impacting visibility and daily routines. This San Diego weather update emphasizes the dense fog affecting many areas.

• Visibility levels: Visibility is currently reduced to less than a mile in many coastal areas, with inland valleys experiencing slightly better visibility, around 3-5 miles. Driving conditions are hazardous in many areas due to low visibility.

• Types of fog: The fog is primarily advection fog, caused by moist air moving over cooler land surfaces. Radiation fog is also contributing in certain low-lying areas.

• Impact on daily life: The dense fog is causing delays in morning commutes, and outdoor activities should be approached with caution. Many schools have reported delayed openings.

• Air quality concerns: While typically not a major concern, prolonged periods of fog can trap pollutants, leading to slightly decreased air quality. Sensitive individuals should monitor air quality reports.

• High and low temperature predictions: Coastal areas are expected to reach highs in the mid-60s (°F), while inland valleys may see highs in the low 70s (°F). Overnight lows will dip into the 50s (°F) in most areas. Mountain areas will experience even cooler temperatures.

• Comparison to historical data: This temperature drop represents a significant deviation from the historical average for this time of year, which typically sees highs in the mid-70s (°F) and lows in the 60s (°F).
