Tule fog sticks around as we expect to see wet weather soon

Friday, December 19, 2025
KINGS COUNTY, Calif. (KFSN) -- A rare sight Friday afternoon, as a ray of sunlight peaked through the clouds in Kings County.

But, for almost a month, the sun has been hiding behind clouds and a thick layer of fog.

Action News caught up with meteorologist Brian Ochs at the National Weather Service Headquarters on Foggy Bottom Road in Hanford to break down what we've been experiencing.

"We've had a persistent pattern of just basically a lot of low level moisture. It's just stuck around from the previous rains back in November, and we've had high pressure over us, kind of keeping a lid on the cooler air, and the moisture goes with that. So as a result, we've had a lot of fog and low clouds," Brian explains.

Although fog is common in the Central Valley during winter months, Brian mentions seeing fog for weeks is rare, "Not this many consecutive days, not that it hasn't happened before, it's happened in the 1960s and the 1970s."



The thick Tule Fog is known as radiation fog, which is created by the radiation the ground gives off at night.

Brian says, although it's typically not a concern, people with respiratory issues should pay attention to the air quality.

"You can get particulate matter, dust and just different things, because when you have high pressure and fog, usually the air gets stagnant and doesn't move around much," says Brian.

Incoming rain could help clear the air, but it comes with its own set of concerns...

"We could see some increased southerly winds. That's another thing we'll have to keep an eye on. There is some concern about trees possibly being down because of the wind, and the grounds being pretty wet too," mentions Brian.



The big question of "When will we see the sun again?" remains.

Especially because a wet Christmas could be followed by more fog.
