Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Weak low pressure over the coastal waters will continue to yield light to moderate winds through midweek. High pressure will develop for the second half of the week and cause the coastal pressure gradient to tighten. This is forecast to bring strong to near gale northerly winds and associated large steep seas. No long period swell is expected for the next 7 days.

Synopsis Cooler than average temperatures, especially inland,
will persist through midweek with low clouds in the overnight and
early morning near the coast and in the valleys. An inland warming
trend is then likely late in the week and into the upcoming weekend
as high pressure builds back over the region.

Discussion As of 01:55 pm pdt Monday... Temperatures are
running up to 6 degrees cooler compared to 24 hours ago as low
clouds persist over the region. This is a result of the deep
marine layer holding on strong at more than 2,000 feet in depth.

While low clouds are finally clearing inland and from the south
off of the big sur coast, do expect a return of stratus again
overnight as a mid upper level low sits off of the southern
california coast. Overall, this will bring about temperatures that
are generally below seasonal averages through midweek.

By midweek and into the upcoming weekend high pressure centered over
the four corners region will begin to build toward the california
coast. This will result in a warming trend, especially for inland
areas, with temperatures rebounding back to or slightly above
seasonal averages. Look for more widespread 80s and 90s inland
during the afternoon hours under mostly sunny skies. This building
ridge will likely compress the marine layer as well with less inland
penetration of stratus late in the forecast period. Meanwhile,
coastal areas will likely remain in the 60s to 70s as onshore flow
persists.

Aviation As of 5:05 pm pdt Monday... For 00z tafs. Clearing
continues at the hour with ksts just having cleared over the north
bay. CIGS are anticipated to return early this evening under a
deep 2200 ft marine layer and moderate onshore flow. Also of note
is a line of clouds moving in from the east. Radar depicts a few
showers associated with these clouds however they are quickly
dissipating and not anticipated to bring showers to any terminals
at this time. Winds will remain light to moderate through this
evening then will gradually dissipate overnight.

Vicinity of ksfo...VFR conditions will prevail through early
evening then return around 04z tonight. BorderlineVFR MVFR cigs
expected through tonight with clearing anticipated around 18z
Tuesday morning. Light to moderate west winds will prevail.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions will prevail through
late this afternoon with low clouds anticipated to return around
02z-03z tonight.VFR CIGS expected through tonight with clearing
anticipated around 19z Tuesday morning. Moderate west winds will
ease overnight becoming light.

MVFR ifr through through early afternoon.

There is a distinct chance that mry never breaks today. Sns should
see a bit of clearing by afternoon, but clouds will remain around
the area and come back early this evening.

Marine As of 05:16 pm pdt Monday... Weak low pressure over the
coastal waters will continue to yield light to moderate winds
through midweek. High pressure will develop for the second half of
the week and cause the coastal pressure gradient to tighten. This
is forecast to bring strong to near gale northerly winds and
associated large steep seas. No long period swell is expected for
the next 7 days.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
