Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Generally light to locally moderate northwest winds will continue across the coastal waters through mid week as high pressure weakens over the eastern pacific and a low pressure system develops off of british columbia. Locally gusty afternoon and evening winds can be expected in the northern san francisco bay around the golden gate and through the delta. The sea state will remain dominated by shorter period northwest waves at around 8 to 10 seconds along with a light southerly swell. Additionally, a lighter more moderate period west to northwest swell will affect the coastal waters through mid week.

area forecast discussion
national weather service sacramento ca
318 am pdt Sun aug 18 2019

Synopsis
Near or below average temperatures expected through Monday.

Gradual warming trend through next week with dry weather
continuing.

Discussion
The delta breeze influence is in full force as early morning
temperatures in most valley locations have dropped into upper 50s
to low 60s. Forecast soundings and href ensemble probabilities
also support marine stratus being advected into the delta region
the next couple of nights mornings. Some of these probabilities
extend eastward toward the sacramento area. But will remain
somewhat cautious with this output given previous instances of
being too robust with the coverage of low clouds. Otherwise,
mostly clear skies should prevail across the region today with
high temperatures roughly 4 to 7 degrees below average. This
equates to valley highs in the mid to upper 80s.

To start the work week, a weak trough off the coast will enhance
the delta breeze allowing for the potential for additional marine
stratus decks. 00z NAM forecast soundings show this marine layer
being a bit deeper than Sunday with a greater eastward extension.

Monday will seemingly be a carbon copy of the previous day with
below average temperatures continuing. Gusty winds will continue
across the delta with 20-30 mph speeds likely to be observed.

Moving beyond Monday, a gradual warming trend is anticipated as a
longwave trough over the eastern pacific lifts up toward western
british columbia. The ever persistent four corners ridge will
expand north and west by the middle of next week. Building
synoptic heights will raise valley temperatures back into the
mid upper 90s with a smattering of triple digits up toward redding
and red bluff. The pattern also supports decreasing delta
influences which allows overnight temperatures to sit above
average by mid-week. ~bro

Extended discussion (Thursday through Sunday)
Ensemble guidance is in good agreement high pressure will remain
in place through the extended forecast period. Warmest day is
forecast to be Thursday with high temperatures right around the
century mark across interior ca. A very slight cooling trend is
then expected going into next weekend before heat builds again the
following week.

Aviation
Vfr conditions next 24 hours. Areas southwest wind gusts 25-30
kts vicinity carquinez strait and west delta. Local southerly wind
gusts 15-25 kts 22z-02z Monday elsewhere.

Sto watches warnings advisories
None.

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.
