Dense Fog and Reduced Visibility

Expect widespread fog, particularly along the coast and in low-lying areas of San Diego County. This San Diego fog can significantly reduce visibility, impacting commutes and outdoor activities. The coastal fog is expected to be especially dense in the mornings and evenings. A fog advisory may be issued by the National Weather Service. Here's what you should do to stay safe:

• Check the latest weather advisories: Before you head out, always check the National Weather Service for the latest San Diego forecast and any fog advisories.
• Drive slowly and cautiously: Reduce your speed and increase following distances significantly when driving in foggy conditions. Visibility is greatly reduced, increasing the risk of accidents.
• Use your headlights: Even during the day, using your headlights will improve your visibility to other drivers.
• Be aware of travel delays: Low visibility can cause delays in air and sea travel. Check with your airline or ferry service for potential disruptions before heading to the airport or harbor.

Cooler Temperatures Across the County

A significant drop in temperatures is anticipated throughout San Diego County. Coastal areas will see a more moderate decrease in the San Diego temperature, while inland regions, such as the mountains and deserts, may experience a more pronounced cooling effect. This temperature change will be noticeable compared to the recent warmer weather. Here's how to prepare for the cooler weather San Diego is experiencing:

• Pack layers of clothing: Prepare for fluctuating temperatures by packing layers of clothing that you can easily add or remove as needed.
• Check your location's specific forecast: The temperature forecast San Diego provides varies across different regions. Check the specific forecast for your area to get the most accurate temperature predictions.
• Be mindful of hypothermia: If engaging in outdoor activities, be extra cautious and aware of the increased risk of hypothermia in the cooler temperatures.

Potential for Showers and Precipitation

While the chances of widespread rain are not high, there is a possibility of scattered showers, particularly in the mountain and inland areas of San Diego County. The likelihood and intensity of the San Diego rain will vary across different regions. The precipitation forecast indicates a greater chance of showers in higher elevations. Here's what you should do:

• Keep an eye on the radar: Stay updated on the latest forecasts and monitor the radar to track the movement of any showers.
• Have an umbrella handy: It's always a good idea to have an umbrella with you, just in case scattered showers develop.
