Marine Weather and Tides
Antioch, CA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... High pressure over the eastern pacific and a thermal trough over inland california will keep gusty northerly winds across the coastal waters through tonight. Gusty winds will generate steep wind waves creating hazardous sea conditions, particularly for small vessels. Winds will subside tonight as a southerly surge pushes northward shifting the winds along the inner coastal waters out of the south. Winds will pick up again on Monday as an upper trough moves through to the north.

national weather service sacramento ca
325 pm pdt Sat jun 23 2018

Synopsis
Hot and dry weather through the weekend. Temperatures return to
near normal next week.

Discussion
Temperatures peak today as upper level ridging builds over the
region, with widespread high temperatures in the valley generally
103-107 this afternoon. At 3 pm, it was generally 1 to 5 degrees
hotter than this time yesterday. The hottest location in the area
was vacaville at 101. It's possible we may see some locations
approaching record levels. The sacramento forecast high is 105,
with the record 106 set in 1988 and the stockton forecast high
106, record 108 in 1964. A heat advisory continues into early
Sunday evening, including an expanded area into northern lake
county. The heat advisory continues until midnight tonight for
the delta, when a delta breeze will begin to bring some relief
locally. This may be strong enough to reach the sacramento area
Sunday afternoon and keep highs below triple digit levels as a
trough moves in and the ridge axis shifts eastward. Northerly
winds have been quite breezy today, gusting up to around 30-35.

These winds combined with very low minimum humidity levels (less
than 10 percent in spots) are bringing critical fire weather
conditions. Any fire starts could spread rapidly. A number of
grass fires have already been reported in the area. A red flag
warning continues into early Sunday evening.

Monday and Tuesday will see more normal temperatures and a shift
to onshore winds, with highs generally in the 90s. This will
significantly cool temperatures at night, and bring some improving
humidity levels. Ek
ek
.Extended discussion (Wednesday through Saturday)
upper troughing over the west coast will keep daytime highs near
or slightly above average for the beginning of the extended
forecast. Models differ by the end of next week as a trough moves
into the pacific NW and dives southward. The latest ec keeps the
trough farther east, and allows ridging to build in behind it over
norcal. Meanwhile, the GFS is the most aggressive solution and
digs the trough into the great basin. As a result, forecast
confidence is low in terms of daytime highs (i.E. Much warmer or
near normal) depending on which solution verifies. No
precipitation is expected through the period.

Aviation
Vfr conditions the next 24 hours. Gusty north winds 10-20 kt with
local gusts up to 35 kt expected through 03z Sunday.

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.
