Marine Weather and Tide Forecast for Fremont, CA

SHORT TERM
(This evening through Wednesday)
Issued at 110 PM PST Tue Jan 14 2025

Clear skies for all once again today as weak offshore flow continues. Tonight and tomorrow will be much of the same story as today with chilly overnight temps and a mild, cloudless afternoon.
Temperatures this morning verified the Frost Advisory in all areas where it was issued (just based on the ambient temperature), but conditions are too dry to actually have frost formation in many areas. However, we continue to issue advisories based on the ambient temperature for societal impacts.

LONG TERM
(Wednesday night through next Monday)
Issued at 110 PM PST Tue Jan 14 2025

The upper low that resulted in breezy winds yesterday morning has closed off and is now lingering over the waters off the coast of SoCal away from much of its initial jet influence. Therefore, it is expected to eventually fill in and move inland by late this week. This will promote some breezy winds Friday and Saturday afternoons, but not expecting anything impactful at the moment.
The main point of interest this weekend will be the overnight temperatures once again, with morning lows in the 30s for most of the region outside of the immediate SF Peninsula and Sonoma coastlines. Otherwise, there is high confidence that a blocking ridge pattern will setup and persist well through the extended forecast period with no rain in sight. We are particularly worried yet since the energy release component of some larger fuels is still below critical. However, drying out beyond critical can occur very quickly over the next two weeks, especially if we make it into the first half of February without any rainfall. In comparison to last year and to serve as a reminder that these mid-season dry spells are not entirely uncommon, areas south of the Bay Area that are significantly drier than the North Bay have actually seen more rainfall up to this point in the water year compared to last year. The caveat to that is that we had a few prolific rainmakers to kick off February 2024 and bring us back to normal. It may be alarming how dry we are right now, but we still have time to potentially turn it around.

AVIATION
(00Z TAFS)
Issued at 413 PM PST Tue Jan 14 2025

VFR through the TAF period for all but the North Bay which will see some pockets of fog overnight. Winds mostly stay light to moderate with local effects driving most of the wind directions though the TAF period. Winds around the Monterey Bay will be slightly more unified as overnight southeast drainage winds affect the area.

Vicinity of SFO...VFR through the TAF period. Moderate northwest winds last into the late night before becoming light and variable for Wednesday morning and through that afternoon. Additional moderate northwest winds arrive Wednesday evening.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through the TAF period. Moderate northwest winds weaken into the night and turn into southeast drainage winds overnight. These winds will arrive later into the night for SNS, but will be more moderate compared to the lighter winds at MRY. Expect moderate northwest winds to return mid Wednesday afternoon.

MARINE
(Tonight through next Monday)
Issued at 413 PM PST Tue Jan 14 2025

Mostly light northerly winds continue through the end of the week with seas continuing to ease. Sea state will be low with moderate period into the weekend, but look to build over the weekend.

BEACHES
Issued at 950 AM PST Tue Jan 14 2025

There is a slight risk of sneaker waves as the tide goes out this afternoon, with low tide around 6 PM PST. The large tidal swings resulting in a draw down of water will help mitigate the risk somewhat but remember to never turn your back on the ocean and observe the beautiful sunset over the water from a safe distance.
