Hold Onto Your Hats: Gusty Winds and Chilly Skies Sweep Through San Diego

Morning: A Blustery and Chilly Start

San Diegans waking up this Sunday, January 25, 2026, are greeting a crisp and notably blustery start to the day. Early morning conditions remain clear but cold, with temperatures hovering around 46°F near the coast and dipping even lower in the inland valleys. The primary weather story for the early hours is the wind. The National Weather Service has issued a Wind Advisory in effect until 1:00 PM today, primarily impacting the mountain passes and foothills. Residents can expect north to northeast winds ranging from 20 to 30 mph, with isolated gusts reaching up to 55 mph in wind-prone areas like the Santa Ana Mountains.

For those heading out for early morning errands or coastal walks, the wind chill will make it feel significantly colder than the actual thermometer reading. Drivers, especially those in high-profile vehicles, are urged to use extra caution on east-west corridors where crosswinds may be most intense.

Afternoon: Clouds Roll In as Winds Diminish

As we transition into the afternoon, the intense wind gusts are expected to subside following the expiration of the advisory at 1:00 PM. However, the clear morning skies will give way to increasing cloud cover. Temperatures will climb to a modest daytime high of approximately 64°F to 65°F, which remains slightly below the seasonal average for late January.

• Temperature High: 65°F
• Wind Conditions: 15-25 mph, decreasing after 1 PM
• Sky Cover: Transitioning from clear to mostly cloudy

The afternoon will feel temperate but muted due to the lack of direct sunlight. It is an ideal day for indoor activities or layered outdoor excursions, as the lack of solar heating and the lingering breeze will keep the air feeling quite brisk throughout the county.

Evening and Night: Increasing Humidity and a Slight Chance of Drizzle

By Sunday evening, the cloud cover will thicken significantly. Nighttime temperatures are forecast to drop back down to a low of 48°F. While no major storm systems are currently threatening the region, the high humidity levels—peaking near 94%—and the dense marine layer may produce patchy mist or a light drizzle in some coastal neighborhoods. There is a nominal 10% chance of measurable precipitation late tonight into early Monday morning.

Looking ahead to the work week, the cooling trend is expected to persist, making today’s cool temperatures the new normal for the final days of January. Ensure your patio furniture is secured from the morning's gusts and keep a light jacket handy if you are planning to be out after sunset.
