KEY MESSAGES

Updated at 1238 PM PST Fri Nov 28 2025

- Mild and quiet, beautiful weather through the weekend.

- Pattern continues into much of next week. Breezy offshore winds in the North Bay interior Wed/Thu. Minimal impact.

- Need to look just beyond the 7 day forecast for next chance of rain. High uncertainty if we'll actually get any then.

SHORT TERM

Issued at 1238 PM PST Fri Nov 28 2025 (This evening through Saturday)

Stagnant pattern remains. Beautiful weekend full steam ahead, unless you're caught up in the Tule fog and stratus in the interior East Bay and North Bay. These locations will hold on to fog and clouds through much of the day today, and will likely copy/paste tomorrow as well. Believe it or not, Santa Rosa is actually one degree warmer than this time 24 hours ago! Elsewhere we're seeing temps around seasonal normals with highs in the upper 50s and lower 60s.

LONG TERM

Issued at 1238 PM PST Fri Nov 28 2025 (Saturday night through next Thursday)

Pretty benign conditions through much of next week. One notable period for now looks like Wednesday and Thursday mornings where we are likely to see some breezy offshore winds in the North Bay interior thanks to the deep retrograding low to our south that we've been mentioning. At the moment this doesn't appear like it'll cause any issues. As we get into the latter half of the week, there is some uncertainty regarding how this low will act as it weakens and starts to finally get caught up in the steering flow, pulling it eastward. Looking just beyond the 7 day period may bring us our next light rain maker as the system moves back ashore. This still being very uncertain, but it's at least the next reasonable time for actual rain.

AVIATION

(06Z TAFS) Issued at 935 PM PST Fri Nov 28 2025

Low clouds and pockets of fog are reestablishing as winds reduce into the night. Expect nearly widespread CIGs by the late night. Slightly drier flow affects the region tomorrow with increasing winds. This will offer earlier clearing times, and lead to widespread VFR by the mid afternoon. Low CIGs return again into Saturday night as winds reduce across the region.

Vicinity of SFO...Expect mostly light winds through the TAF period. IFR CIGs are building around the SF Bay and look to become more consistent later into the night. These CIGs scatter into the late morning and cloud cover clears as winds turn northwest into Saturday afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Low clouds and pockets of fog have formed around the Monterey Bay and are affecting the terminals while winds have become light. Cloud cover erodes into the late morning as northwest winds build, but these winds look to become light and variable into Saturday night.

MARINE

(Tonight through next Thursday) Issued at 935 PM PST Fri Nov 28 2025

Winds continue to decrease into the night, but will increase into early Sunday. Hazardous marine conditions return in the late weekend as swell heights increase. Winds increase and wave heights build due to incoming long period westerly swell in the mid work week.

BEACHES

Issued at 338 AM PST Fri Nov 28 2025

Moderate to long period northwesterly swell will result in an increased risk for sneaker waves and rip currents. Breaking waves of 13 to 18 feet are expected. A beach hazards statement is in effect for the coastline from Sonoma County to Monterey County through 10 PM PST Sunday evening. Sneaker waves can unexpectedly run significantly farther up the beach than normal, including over rocks and jetties. Rip currents are typically more frequent and stronger in the vicinity of jetties, inlets, and piers.
