A Gray Start to the Work Week: Overcast Skies and Late Showers Loom Over the Bay

Morning: A Chilly, Damp Start for Commuters

San Francisco residents are waking up to a blanket of thick, low-hanging clouds this Monday morning, February 23, 2026. As of the early hours, temperatures are hovering around a cool 52°F, with humidity levels sitting high at approximately 90%. While the pavement remains mostly dry for the morning drive, the air feels heavy, and the typical San Francisco fog is expected to linger through the morning commute. Visibility may be slightly reduced near the coast and the Golden Gate, so drivers should exercise caution.

Afternoon: Peeks of Warmth Amidst Persistent Clouds

By midday, the city will see a slight rise in mercury, with daytime highs expected to reach between 61°F and 65°F. Despite the mild temperatures, do not expect much in the way of sunshine; the sky will remain predominantly overcast throughout the afternoon. Wind speeds are beginning to pick up, shifting to a steady south-southwest flow at approximately 19 miles per hour (31 km/h). This "fresh breeze" will make the afternoon feel significantly cooler than the recorded temperature, particularly for those in wind-prone neighborhoods like the Sunset District or Twin Peaks.

Evening and Night: Rain Gear Highly Recommended

The real shift in conditions arrives after sunset. Forecasters are predicting a transition from cloudy to damp as a light rain system moves into the region. While the chance of precipitation during the day is a mere 10%, that probability jumps to 35% by the evening hours. Temperatures will dip back into the low 50s, reaching an overnight low of 50°F to 53°F. If you are heading out for dinner or a late-night stroll, an umbrella or a water-resistant jacket is a necessity, as intermittent light rain is expected to persist through the night and into early Tuesday morning.

Wind and Rain Outlook: No Major Alerts, but Stay Alert

While the National Weather Service has not issued any severe wind or flash flood warnings for today, the combination of gusty winds and incoming moisture marks the beginning of an unsettled weather pattern for the week. Highlights for today include:

• Temperature Range: A high of 65°F and a low of 50°F.
• Wind Conditions: South-southwest winds at 19-20 mph, with occasional higher gusts near the water.
• Rain Probability: Increasing to 35% after dark.
• Commuter Impact: No major weather-related delays are currently reported for ferry services or bridge traffic, but wet roads tonight could create slick conditions for the Tuesday morning commute.
