San Diego woke under a low, cloudy blanket today, with temperatures near 66°F at the airport and a sticky marine layer hugging the coast. Patchy fog is likely to linger into mid-morning before skies clear to mostly sunny and the high climbs to around 77°F.
Foggy Mornings, Sunny Afternoons
Drivers along the shoreline and in bayside neighborhoods can expect reduced visibility for the morning commute as low clouds and patchy fog hang on through the first half of the day. The marine layer should thin by late morning, and a light west wind of 0 to 10 mph will help keep coastal highs in the 70s while inland areas heat up more quickly into the afternoon. If you're on the road early, allow extra time and use headlights to help with visibility.
Inland Heat Risk and Coastal Tides
According to the National Weather Service San Diego, Heat Advisories are in effect from 10 AM today through 8 PM tomorrow, for inland valleys and mountains, and an Extreme Heat Warning remains in effect for the lower deserts through 8 PM tomorrow. Forecasters expect mid-90s to around 105°F for many inland spots and 112 to 118°F in the lower deserts, while the coast stays in the mid-70s. The NWS also notes astronomical high tides of 7.0 to 7.2 feet are forecast for July 12 to 14. Combined with a modest south swell producing 4 to 6 foot surf, those evening high tides may push water onto boardwalks and low-lying beach streets.
Where To Cool Off
San Diego County runs a network of public Cool Zones, air-conditioned libraries, recreation centers, and other spots, for people who need relief from the heat. See the San Diego County Cool Zones list and interactive map for locations. If you need help finding a site or arranging transportation, call 2 1 1 for assistance.
Commute and Outdoor Tips
Plan beach visits and waterfront errands for the afternoon when fog clears, and avoid outdoor work or strenuous exercise in inland areas during peak afternoon heat. Stay hydrated, check local forecasts for advisory updates, and keep an eye on evening tides if you'll be near low-lying parts of the shoreline later this week.
