Clear Morning Skies Give Way to a Blustery Evening Shift in San Diego

A Day of Two Halves for America's Finest City

San Diegans waking up this Monday, February 9, 2026, will be greeted by relatively calm conditions, but local forecasters are advising residents to keep their rain gear handy as the day progresses. While the morning begins with clear to partly cloudy skies and a refreshing start, a significant pattern change is expected to sweep through the region by the afternoon and evening hours, bringing wind and a likelihood of precipitation.

Morning: A Bright and Crisp Start

The day began with a sunrise at 6:37 AM, revealing temperatures starting in the mid-50s. Early commuters likely noticed high humidity levels near 79%, contributing to a damp feeling in the air despite the lack of immediate rain. Through the mid-morning hours, conditions will remain largely dry and pleasant, making it an ideal window for outdoor exercise or running errands before the atmospheric shift begins.

Afternoon: Peaking Temperatures Before the Turn

By midday, San Diego is expected to reach a daytime high of approximately 75°F. While the sun will make several appearances, cloud cover will gradually thicken from the coast inward. The humidity will stabilize around 71% as the region prepares for an incoming weather system. This afternoon window represents the warmest part of the day, offering a brief period of classic Southern California mildness before the wind picks up.

Evening and Night: Wind Advisories and Incoming Rain

As sunset approaches at 5:28 PM, the weather story changes significantly. A Wind Advisory has been issued for the area as a new storm system approaches from the Pacific. Evening temperatures will dip back toward 55°F, and the chance of rain will climb to 20% shortly after nightfall. Forecasters predict that patchy light rain—and potentially a stray thunderclap—will begin late tonight. This is the leading edge of a broader system expected to bring moderate rain and mountain snow to the county through early Thursday morning.

Summary of Conditions and Warnings

• Temperature Range: High of 75°F; Low of 55°F.
• Wind: Increasing gusts throughout the evening; Wind Advisory in effect.
• Precipitation: 10% chance during the day, rising to 20% at night with moderate rain expected after midnight.
• Marine/Mountain Alerts: Mountain snow is expected for elevations above 5,000 feet starting late Monday night.

Residents are encouraged to secure loose outdoor items and prepare for a wet Tuesday commute as the primary force of the storm arrives overnight.
