685 FXUS66 KMTR 100128 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 628 PM PDT Mon Jun 9 2025 ...New AVIATION, BEACHES... .SYNOPSIS... Issued at 246 PM PDT Mon Jun 9 2025 Remarkably stable weather pattern this week with temperatures generally near the seasonal average, marine layer clouds each night and morning, and breezy onshore winds each afternoon and evening. && .SHORT TERM... (This evening through Tuesday) Issued at 246 PM PDT Mon Jun 9 2025 The picture from space this afternoon is mesmerizing as stratus flows over our waters and hugs the coast. You can also see some stratus lingering in select interior areas such as Marin County, around San Francisco and Oakland, and hugging interior northern Monterey County. There may be some additional give in these areas or along the immediate coast, but that will be short lived. Stratus is expected to surge back inland tonight, similar to what we saw last night. This means we could also see pockets of drizzle where the marine later is thickest tomorrow morning. Otherwise the forecast is more or less on repeat with temperatures being near normal to slightly below normal. && .LONG TERM... (Tuesday night through next Sunday) Issued at 246 PM PDT Mon Jun 9 2025 Upper level ridging gets flattened on Wednesday as an upper level shortwave trough quickly passes over southern OR and northern CA. This will leave us with quasi-zonal flow through mid to late week, with an upper level trough moving in for the weekend. The forecast is generally going to be on repeat with cloudy nights and mornings, breezy onshore flow during the afternoon and evenings, and near seasonal temperatures. && .AVIATION... (00Z TAFS) Issued at 628 PM PDT Mon Jun 9 2025 Onshore winds supported by a currently strong 4.8 mb SFO-SAC pressure gradient will continue to usher stratus /MVFR-IFR/ inland tonight and Tuesday morning. Patchy light coastal drizzle is possible as well. Stratus mixing out back to near the immediate coastline Tuesday afternoon then stratus moves inland Tuesday night and early Wednesday. Vicinity of SFO...Stratus /MVFR-IFR/ tonight and Tuesday morning. Stratus mixing out to scattered clouds /VFR/ Tuesday afternoon then stratus /MVFR/ moving inland Tuesday evening and night. West wind periodically gusting to 25 knots through mid evening, though because of a currently strong 4.8 mb SFO-SAC pressure there may a few higher gusts this evening.

Monterey Bay Terminals...Stratus /MVFR-IFR/ tonight and Tuesday morning. Patchy light drizzle tonight and Tuesday morning. Stratus lifting to MVFR-VFR by late Tuesday morning or early afternoon.

(Tonight through next Saturday) Issued at 246 PM PDT Mon Jun 9 2025 Fresh northwest breezes persist across the waters through mid week, becoming strong for the second half of the week. A low, amplitude, long period southwesterly swell persists through Tuesday morning, bringing enhanced currents. Near gale force winds possible over the outer waters by the end of the week. && .BEACHES... Issued at 617 PM PDT Mon Jun 9 2025 A long period southerly swell will enter the waters today into Tuesday bringing a higher risk for rip current along beaches. Breaking waves about 5 to 7 feet, but strong currents and sneaker waves will be the bigger hazard. Use caution near the water and never turn your back on the ocean. && .MTR WATCHES/WARNINGS/ADVISORIES... CA...None.
