So much for Rat's global warming BS... I knew it was fake...

Bay Area breaks 103-year-old temperature record as Calif. freezes

By Olivia Hebert, News Reporter Dec 1, 2025

What began as a murky stretch of gray across the Bay Area is now settling into a week defined by stubborn Tule fog, colder-than-normal daytime highs and an incoming burst of offshore winds, according to the National Weather Service.

In the weather service’s Monday forecast discussion, forecasters wrote that a persistent pattern of high pressure to the west and lower pressure to the east has allowed Central Valley fog to spill into Bay Area counties for several days.

“It’s called a Tule fog, but that’s just a local reference to the phenomena that sets up in general, usually in the early winter,” weather service Bay Area meteorologist Roger Gass told SFGATE. After a wet October and November, he added, the saturated lower atmosphere has been “trapping moisture in the lower levels, resulting in this fog.”

Just a week earlier, the Bay Area Air District issued a Spare the Air alert through Thanksgiving as the same stagnant fog layer and winds trapped high concentrations of pollution near the surface. Burning wood or other solid fuels was temporarily banned, with officials warning the conditions posed heightened risks for vulnerable residents.

The slow-clearing fog kept San Francisco unusually cold Sunday, breaking a 103-year-old temperature record. The city reached only 50 degrees, edging out the 51-degree high for Nov. 30 set in 1922.

Elsewhere in the state, the weather service issued a freeze warning for parts of Southern California, including Death Valley, from Monday evening through Tuesday morning. The warning noted temperatures could dip as low as 30 degrees and cautioned that frost and freezing conditions could affect crops and damage unprotected outdoor plumbing.

The fog will continue to influence temperatures through Monday, the weather service said, with much of the North Bay and East Bay expected to remain socked in with temperatures similar to Sunday’s readings. But conditions are forecast to shift Tuesday night into Wednesday as a new system to the east introduces a round of gusty offshore winds.

Gass said forecasters are expecting an “insider slider” pattern, a cold and dry low-pressure system that will slide down through the Great Basin. Gusts anywhere from 30 to 45 miles per hour are expected in higher elevations in the Bay Area, with harsher gusts forecast at the highest peaks.

The winds will likely be strongest overnight and into the early morning hours. Lower elevations may see weaker offshore flow early Wednesday before onshore winds redevelop by afternoon.

“The offshore winds will help mix out the boundary layer,” Gass said, reducing the threat of widespread fog for several nights. Localized pockets may still form in parts of the North Bay, including the Russian River Valley, but conditions should be drier overall.

Hazardous surf continues along the coast from Sonoma to Monterey counties, with breaking waves of 10 to 14 feet and long-period forerunners increasing the risk of sneaker waves, according to the weather service. Some favored breaks may exceed 20 feet. A beach hazards statement remains in effect through Wednesday evening.

King tides are forecast to arrive Tuesday and linger through Sunday, bringing the highest astronomical tides of the season and prompting a coastal flood advisory for vulnerable shoreline areas during morning high tides.

“We are expecting coastal flooding in the Bay Area Tuesday through Sunday during the times of high tide,” Gass said.

Beyond this week, forecast models point to a shift away from the cold pattern. The Climate Prediction Center’s 6-to-10-day and 8-to-14-day outlooks “show a warming trend” as we move deeper into December, Gass said.

While the weather service is monitoring signs of a potential pattern change mid-month, recent ensemble guidance continues to favor quiet, dry conditions after Wednesday’s offshore winds pick up steam.
