Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Northwest winds will increase across the coastal waters as high pressure builds over the eastern pacific and low pressure develops over central california. Locally gusty coastal jets are forecast south of point arena, pigeon point, and point sur that will create hazardous seas conditions for smaller vessels. Breezy afternoon and evening winds are also forecast over the san francisco bay as well as over the Monterey bay. Mixed seas will continue with shorter period northwest waves at around 8 to 10 seconds, a light longer period west swell, and a light southerly swell.

Synopsis Light rain will continue across del norte and northern
humboldt counties through this evening and then quickly come to an
end overnight. Otherwise, warmer temperatures are expected over the
interior from Thursday into early next week as marine cloudiness
returns to coastal areas.

Discussion A weak front is spreading light rain over the
northern half of the area this afternoon as an upper level trough
pushes inland over the pacific northwest. The nearly complete
erosion of the marine layer coupled with a few peaks of sunshine
in advance of the trough has allowed for an anomalously warm day
along the humboldt coast as temps have climbed into the mid to
upper 70s.

The trough and associated front will quickly depart to the east
tonight and give way to a weak northwest flow regime for the end of
the work week. This will allow the marine layer to redevelop and
bring stratus back to coastal areas the next few days, following the
typical diurnal trend with partial clearing during the afternoon.

Elsewhere, gradual height rises will support a warming trend across
the interior over the next several days as 850 mb temps climb from
the mid to upper teens into the low 20s c. No additional
precipitation is expected through the middle of next week at this
time. Cb

Aviation Widespread cloud cover blankets much of the area north
of CAPE mendocino this afternoon. Periodic showers will continue to
impact both coastal terminals through this evening. Dips to MVFR
will be possible with any heavier showers. Model guidance suggests
that marine stratus will reform tonight along the coast, likely
lowering ceilings and visibilities once again. Elsewhere, mid to
high clouds will continue to pass over the interior, withVFR
conditions expected to prevail.

Marine Northerlies will begin to ramp up on Thursday, leading to
the development of steep, short-period seas. The gale watch was
upgraded to a gale warning for the northern outer waters. Hazardous
seas will likely propagate into the southern outer waters,
leading to an upgrade of the hazardous seas watch to a hazardous
seas warning for this zone. Small craft advisories were also added
for both inner water zones given the increasing winds and
building steep seas. Winds will remain elevated through early on
Saturday and weaken through the day. Northerlies will once again
increase over the outer waters beginning Monday morning. Seas will
peak early on Friday and gradually diminish through the weekend.

Otherwise, a westerly swell will linger through Thursday, before
an additional westerly swell moves through the waters this
weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
