Marine Weather and Tide Forecast for Daly City, CA

SHORT TERM
Issued at 219 PM PDT Wed Oct 14 2026 (This evening through Thursday night)

Weak offshore flow today offers little to see on satellite with bright sunny skies area wide. Offshore ridging over the EPAC is helping to lift temperatures to near normal for most locations today. We're seeing breezy winds across higher elevations, that have peaked between 20-25 MPH so far this afternoon. We're not expecting winds to exceed those speeds for the remainder of the day. While we don't have a a FWW or RFW out, we are messaging elevated fire weather concerns across our area, especially where the gustiest winds are at higher elevation locations in the North Bay and East Bay Hills due to critically dry fuels today and through the remainder of the week. Expect another night of clear skies as offshore erodes any marine layer influence overnight.
Radiational cooling with the clear skies will result in some cool spots in interior valley locations, while at higher elevations we'll see warmer spots from thermal belting above 1000ft.

LONG TERM
Issued at 219 PM PDT Wed Oct 14 2026 (Friday through next Tuesday)

Elevated to near critical fire concerns continue through the remainder of the week into the beginning of the weekend on Saturday with similar warm, dry and windy conditions especially at higher elevations. The offshore flow, thermal belting and warmer daytime temperatures will result in continued poor overnight recovery and even worse daytime retention through Saturday across the interior.
By Sunday, a notable pattern change will shift us back to widespread onshore flow, while a cold front drops temperatures considerably by Sunday afternoon into the beginning of next week. The trough associated with the pattern change will also bring increasing chances for scattered light rain beginning later Monday into Tuesday. The position of the upper level low dropping out of the Gulf of Alaska will determine where the most rain falls, currently focused primarily on the Central Coast with less than a 0.25" between late Monday and Wednesday expected at most.

AVIATION
(18Z TAFS)
Issued at 1055 AM PDT Wed Oct 14 2026

VFR conditions are forecast for much of the region through the TAF period as high pressure builds in from the eastern Pacific. As mentioned earlier, some of the high resolution models are showing stratus developing late tonight and into Thursday morning, yet mainly along the coast of the North Bay and San Francisco Peninsula. Onshore winds are forecast to return by early afternoon and prevail into the early evening before becoming light/variable and then weak offshore early Thursday morning. Medium to high confidence for inland and low to moderate for coastal sites.

Vicinity of SFO...VFR. Light/variable to offshore flow this morning becoming onshore by early afternoon. Winds are forecast to be west- northwest between 10-15kt before easing after sunset.
Weak offshore flow is forecast after sunrise before becoming onshore by early Thursday afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR. Onshore winds have returned to MRY while drainage (southeasterly) winds persist at SNS. Onshore flow is expected by early afternoon at both terminals before easing after sunset.

MARINE
(Today through Monday)
Issued at 1055 AM PDT Wed Oct 14 2026

Seas will continue to subside through tonight with moderate seas expected for the offshore zones through the week while nearshore waters observe moderate to slight seas. During this time frame gentle to fresh northerly breezes persist. Moderate to fresh northerly winds return for the weekend, which should lead to rough seas.

FIRE WEATHER
Issued at 502 AM PDT Wed Oct 14 2026

Elevated to near critical fire weather conditions are expected for the higher elevations late tonight through Friday morning. The main areas of concern will be for the North Bay Interior Mountains and East Bay Hills. The strongest winds look to be over the North Bay Interior Mountains where gusts 30-40 mph are possible, perhaps up to 45mph or higher for the highest elevations. The East Bay Hills will be breezy as well, but may be closer to 25-35 mph with locally higher gust for exposed ridges and areas of higher terrain. Both areas will be dry with poor overnight RH recovery, which combined with the breezy winds, warmer weather, and available fuels leads to the elevated to near critical fire weather conditions.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Coastal Flood Advisory until 4 PM PDT this afternoon for CAZ506.

PZ...None.
