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
233 pm pdt Sun aug 18 2019

Synopsis
Near or below average temperatures expected through early this
week. Gradual warming trend by mi-week with dry weather
continuing.

Discussion
Below normal temperatures continue across interior norcal, with
afternoon temperatures running 3 to 10 degrees cooler than 24
hours ago. This is due to a deep marine layer (about 3000 feet as
of this afternoon), and enhanced onshore flow continuing through
the delta. Model guidance continues to favor coastal stratus
through the delta region the next couple of nights mornings.

Otherwise, mostly clear skies will prevail.

Below normal temperatures will continue on Monday, with valley
locations in the mid 80s to mid 90s, and low 60s to low 80s over
the mountains. Gusty winds will continue across the delta with
20-30 mph speeds likely to be observed.

Looking beyond Monday, a gradual warming trend is expected through
the period. Temperatures will be right around average on Tuesday,
then trend above seasonal normals by mid- week. Most valley
locations should see temperatures generally in the mid to upper
90s, while highs up to around 102 are expected over the northern
sacramento valley by mid-week. Dry weather will continue through
the period.

Extended discussion (Thursday through Sunday)
A persistent high pressure pattern is settling in over the region
allowing for some seasonably warm temperatures. Many locations
are forecast to be 5 to 10 degrees above average with little day
to day change in temperatures through the extended period.

Aviation
Vfr conditions next 24 hours. Gusts to 30 kts delta vicinity.

Typical diurnal wind patterns for the summertime in ca. Local
gusts up to 15-20 kts from ksac northward through about 06z-09z
Monday.

Sto watches warnings advisories
None.

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.
