SHORT TERM

Issued at 103 AM PST Sun Nov 30 2025 (Today and tonight)

High clouds make life for the meteorologist a little difficult this morning, as it blocks the low level clouds that are being observed in the North Bay, East Bay, and San Francisco region. The question for today, is, you guessed it, much like yesterday and pertains to if or when will the clouds clear out around there. Guidance favors perhaps a few hours earlier today, perhaps the early afternoon hours instead of the mid to late. Given that, opted to go with slightly higher temperature forecast than yesterday's observed temperatures for the N Bay and surrounding areas. Highs will still be below normal there by about 0 to 10 degrees, while the rest of the region is closer to normal for this time of year.

LONG TERM

Issued at 103 AM PST Sun Nov 30 2025 (Monday through Saturday)

The forecast remains on track for the extended period, with the first feature being stratus clearing out for the North and East Bays Monday and Tuesday afternoon. An inside slider remains on tap for midweek, which will bring breezy conditions to the interior North Bay hills Wednesday morning. Conditions will dry out as well in terms of minRH values; however, no major fire weather concerns are expected. Beyond that, the slider looks to dig south, which should allow for upper level ridging to build towards us. Dry weather remains in the forecast with near seasonal to slightly warmer than normal high temperatures expected for the end of the week.

AVIATION

(18Z TAFS) Issued at 954 AM PST Sun Nov 30 2025

Varying conditions from LIFR to VFR this morning depending on where you are. Low ceiling and visibilities will gradually improve to VFR by midmorning or early afternoon, earlier than yesterday. Weak to occasionally moderate offshore winds persist in the higher terrain across the region and is mixing down to the terminals at times this morning. Onshore winds are expected to return this afternoon for a brief period, then become light and variable late tonight and offshore early tomorrow morning across the Bay Area. Low clouds are forecast to return to the Bay Area terminals (potential for fog in and around KSTS) early Monday morning with an earlier clearing time than today. Lower confidence for the Monterey Bay terminals for low ceilings and/or visibilities. Any low clouds and/or fog that does develop are expected to clear earlier on Monday as offshore flow may persist throughout much of the day, especially across the Bay Area terminals.

Vicinity of SFO...IFR to MVFR conditions persist at KSFO, yet conditions are forecast to return to VFR later this morning, just before or around noon. Onshore winds are also expected by this afternoon before becoming variable overnight. Offshore winds are then forecast to return early Monday morning with the potential for IFR/MVFR conditions. As offshore flow prevails early Monday morning and into the afternoon, we are expecting an earlier clearing time compared to today.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR at KMRY and LIFR at KSNS, yet expecting to improve to VFR here in the next few hours. Onshore winds are forecast to increase slightly this afternoon and then ease overnight. Low probability for IFR to sub-IFR conditions early Monday morning, likely around sunrise and shortly there after.

MARINE

(Today through Friday) Issued at 954 AM PST Sun Nov 30 2025

High pressure will remain located off of the Oregon coast maintaining northerly breezes through the week. Northerly flow will increase throughout the day today and gradually diminish into Monday. Winds will be locally stronger over the outer waters and coastal jets. Wave heights and swell energy increase early this week.

BEACHES

Issued at 828 PM PST Sat Nov 29 2025

Hazardous beach conditions will continue into next week with a very energetic surf zone.

A beach hazards statement remains 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.

A set of forerunner waves arrive early next week renewing the danger for sneaker waves.
