Marine Weather and Tide Forecast for Timber Cove, CA

SHORT TERM
(This evening through Saturday)
Issued at 137 PM PDT Fri May 16 2025

Mostly clear sky conditions have returned to the region this afternoon. Afternoon temperatures will be within a few degrees (-5 to +5) of seasonal averages. However, passing high clouds continue over the region. Low clouds are likely to return tonight and into Saturday morning, and push further inland, as we have abundant low level moisture.

Coastal drizzle will also be possible Saturday morning as the marine layer deepens overnight. Low clouds spreading further inland, the deepening of the marine layer, and an approaching trough of low pressure will result in a slight cool down for Saturday afternoon. Maximum forecast high temperatures will range from the mid 50's to mid 60's on northwest facing coastal locations to upper 60's to mid 70's across the interior.
Northwesterly winds are expected by Saturday afternoon with gusts 25-35 mph in lower elevations across the region with stronger gusts up to 45 mph in the higher elevations and just along the North Bay coast.

LONG TERM
(Saturday night through next Thursday)
Issued at 137 PM PDT Fri May 16 2025

Winds ease slightly Saturday night into Sunday morning, with the exception of the higher elevations. Breezy and gusty winds will persist on Sunday afternoon with similar values mentioned above, maybe a tad bit stronger. The aforementioned upper level trough will dig into the Great Basin through Sunday before ejecting further to the east. This will result in northerly, potentially offshore winds in the higher elevations and typically windy gaps and passes of Napa, Contra Costa, Alameda, and Santa Clara counties Sunday night into Monday. This will lead to elevated fire weather conditions as humidity values will be in the 40-50% range Sunday night and as low as 15% on Monday afternoon (again in the higher elevations).

High pressure will begin to build into the Pacific Northwest and northern California in wake of the exiting trough with the warmest day currently anticipated to be Wednesday. Temperatures Wednesday afternoon look to be 5-15 degrees above seasonal averages with mid 60's to mid 70's for coastal areas, mid 70's to lower 80s across the bayshore, and mid 80's to lower 90's across the interior. More of a zonal flow is expected by late next week with the likely return of a shallow marine layer and more seasonal temperatures.
