.SHORT TERM...
Issued at 211 PM PST Sun Jan 11 2026
(This evening through Monday)

Another night of chilly weather is in the forecast as persistent 
ridging keeps the weather quiet for us. The deterministic NBM is 
improving in terms of the forecasted low temperatures in comparison 
to the previous few days. Temperatures this morning trended a few 
degrees cooler than even the adjusted forecast had. Given this, 
decided to blend in this morning's observed temperatures with the 
deterministic NBM to pull tomorrow morning's temperatures down 
slightly. A Cold Weather Advisory has been issued for the North Bay 
Valleys, East Bay Interior Valleys, the southern Salinas Valley, and 
interior San Benito County from 1AM-9AM PST Monday morning. Not a 
fan of chilly mornings? Temperatures warm into the low 60s across 
the Bay Area, 60s across the Central Coast, and even some mid to 
upper 60s in the Salinas Valley. Winds remain light and offshore 
with locally gusty conditions along the coastline. 

A Beach Hazards Statement goes into effect at 5PM this evening and 
will remain in effect through Monday evening. If you are going to 
the beach, use caution and never turn your back on the ocean! There 
is an elevated risk of sneaker waves, rip currents, and larger shore 
break.

.LONG TERM...
Issued at 211 PM PST Sun Jan 11 2026
(Monday night through next Saturday)

Colder mornings continue through at least Tuesday. We'll have to see 
how the current blend does for low temperatures on Monday but a 
similar blend may be needed for Tuesday morning. This would most 
likely necessitate a few Cold Weather Advisories for the coldest 
portions of the interior but they would not be widespread by any 
means. Daytime temperatures warm throughout the week and will be in 
the mid to upper 60s by mid to late week. The Salinas Valley looks 
to be one of the warmer locations with highs reaching the low to mid 
70s this week. Morning temperatures warm as well with a return of 
more seasonal low temperatures in the 40s expected. Winds remain 
light and offshore through the week as upper level ridging 
continues. Wondering when our next chance for rain will be? Models 
are hinting some rain may be possible towards the end of the month 
starting the 21st/22nd but models are not in agreement as to the 
placement of ridging vs troughing over the West Coast. Just know 
that rain is currently unlikely to return through at least mid-month 
with long range guidance indicating some increasing potential by 
late month.

While the Beach Hazards Statement is set to expire Monday evening, 
hazardous beach conditions are likely to return mid to late week. 
Another round of long period swell will result in an increased risk 
of sneaker waves and rip currents Wednesday into the end of the 
week. If you're heading to the beach keep this in mind and make sure 
you never turn your back on the ocean.

.BEACHES...
Issued at 211 PM PST Sun Jan 11 2026

A Beach Hazard Statement will go into effect at 4PM PST this
evening and continue through 6PM PST Monday for all Pacific Coast
beaches. A longer period moderate swell will bring hazardous 
beach conditions with increased risk for rip currents, sneaker 
waves, and larger shore break. This will result in dangerous 
conditions along the shoreline. Hazardous beach conditions are 
expected to continue through Thursday with the issuance of 
additional Beach Hazard Statements likely.

Stay off of jetties, piers, rocks, and other waterside 
infrastructure. Remain out of the water to avoid hazardous surf 
and NEVER turn your back on the ocean. Monitor local weather, surf
and tide forecasts at www.weather.gov/mtr.
