Short Term

, Issued at 156 PM PST Mon Feb 2 2026 (This evening through Tuesday)

The threat for minor coastal flooding is winding down as high tide has come and now past. The only other threat from the previous AD update is that the Beach Hazards Statement remains in effect for Pacific Beaches through this evening. Otherwise, quiet and dry weather continues through the short term thanks to high pressure building over the region. Temperatures tonight will be similar to last night or perhaps a few degrees warmer. Given the building high pressure system, tomorrow's high temperatures will be warmer, putting most areas above their normal seasonal highs by 5 to 15 degrees.

Long Term

..issued at 156 PM PST Mon Feb 2 2026 (Tuesday night through next Sunday)

High pressure dominates the forecast through much of the work week, leading to a warming and drying trend through Wednesday. Cluster analysis shows an upper level trough developing off the California Coast Thursday into Friday, though there is some uncertainty as to where exactly it'll be placed. This could spread some moisture in from the south for us, likely leading to an increase cloud cover and slightly cooler temperatures. The airmass should remain dry enough to keep any showers at bay, but this will be something to watch for.

Friday into the weekend, the aforementioned low looks to be over southern California by Saturday, with ridging setting up over the PacNW. The forecast continues to trend dry for most of Saturday, with chances for precipitation potentially arriving as early as late Saturday night for areas in the far North Bay. Should the clusters pan out, high pressure meanders eastward as a disturbance advances towards the PacNW Sunday into Monday. Chances for rain have bumped up with the latest forecast package, to about 30-40% for the North Bay region and the San Francisco peninsula coast. Interior areas, like South and East Bay are closer to the 30-35% range and for the Central Coast chances are lower about 15-35%. What does that mean? Regardless of rain chances, expect cooler conditions to prevail with the return of onshore winds, and some cloud cover. Rainfall amounts at this time remain light, with perhaps some areas seeing vicinity showers on Sunday.

Aviation

(18z TAFS) Issued at 920 AM PST Mon Feb 2 2026

VFR conditions will continue to prevail at all taf sites today and through most of the night, with relatively light and variable winds, with high confidence. However, confidence is more moderate, as there is the potential for some fog formation again tonight, especially for STS, which would result in sub-VFR conditions.

Vicinity of SFO, VFR conditions with light southerly flow will continue to prevail. High confidence in VFR through the TAF period. Diurnal winds will prevail today, with offshore flow returning tomorrow.

SFO Bridge Approach, Similar as SFO.

Monterey Bay Terminals, Currently VFR with drainage winds at both terminals. High confidence in VFR through the TAF period. Diurnal winds will prevail.

Marine

(today through Saturday) Issued at 815 AM PST Mon Feb 2 2026

Hazardous conditions will continue today for the inner waters and outer waters due to rough seas and fresh to strong northerly breezes. Conditions improve tomorrow as moderate seas and a gentle northeasterly breeze prevails through Thursday. By Friday, seas build to become rough, and northwesterly breezes increase to become moderate once again.

Beaches

Issued at 257 AM PST Mon Feb 2 2026

Hazardous beach conditions will continue through this evening at Pacific Coast beaches. Long period westerly swell will bring an increased risk for sneaker waves and strong rip currents with breaking waves of 14 to 19 feet. Remember: stay off of jetties, piers, rocks, and other waterside infrastructure, remain out of the water, and never turn your back on the ocean!
