Overcast Skies and Coastal Swells: A Cool Thursday for San Diego

Cooler Conditions Settle Over San Diego

After a stretch of unseasonably warm weather earlier this month, San Diego residents can expect a more traditional winter feel today, Thursday, February 12, 2026. A secondary storm system is currently tracking just south of the region, and while the bulk of the moisture is expected to stay away from the county, it is bringing a noticeable increase in cloud cover and a continued dip in temperatures. Today marks a distinct shift toward cooler, moodier weather across the Southland.

Morning: A Crisp and Partly Cloudy Start

The day began with relatively cool and humid conditions. During the early morning hours, temperatures in the city hovered in the high 50s, accompanied by humidity levels reaching as high as 94%. Early commuters likely experienced partly cloudy skies and filtered sunlight. However, as the morning progresses, moisture from the passing southern system is beginning to thicken the cloud deck. Winds remain relatively calm but are expected to shift as the day warms up.

Afternoon: Clouds Thicken as Temperatures Peak

By mid-day, the transition from partly cloudy to fully overcast will be complete. The daytime high is forecasted to reach approximately 65°F to 66°F, which is a sharp cooldown compared to the balmy conditions seen earlier in the week. Despite the heavy cloud layer, the chance of significant rainfall remains low for the city, holding steady at around 10%. Residents in the coastal and valley regions should expect steady north-northwest winds of 10 to 15 mph, which may make the afternoon feel slightly chillier than the thermometer suggests.

Evening and Night: A Gloomy but Dry Outlook

As the sun sets, the overcast conditions will persist throughout the night. Temperatures are expected to drop to a low of approximately 53°F to 55°F. While the atmosphere may feel damp and heavy, the current trajectory of the offshore storm ensures that San Diego avoids any major downpours for the time being. It will be a gray evening, suitable for those who have been waiting to break out their winter layers and jackets.

Coastal and Surf Conditions

The National Weather Service indicates that while the rain is brushing past us to the south, the ocean is still reacting to the offshore energy. Beachgoers and surfers should be aware of a surge in surf levels today, with waves building to between 4 and 6 feet. Occasional sets could reach as high as 8 feet, particularly at west-facing beaches. Strong rip currents are a significant concern, and local officials are advising swimmers to exercise extreme caution. Looking ahead, the region may see a brief return to sunshine by Friday afternoon before the next weather system arrives next week.
