PZZ500 227 Pm Pdt Sat Jul 4 2020
Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Winds are strong and out of the northwest over the coastal waters this afternoon and continuing into the evening and will continue through the holiday weekend. The results of the strong winds will generate steep fresh swell resulting in hazardous seas conditions, particularly for smaller vessels. The long-period southerly swell prevails through the weekend as well. This will cause occasional breaking waves over nearshore shoals and strong currents along the coast, especially near points and headlands.

Area Forecast Discussion National Weather Service San Francisco Bay Area 650 PM PDT Sat Jul 4 2020

SYNOPSIS. High pressure will remain over the region through the remainder of the weekend resulting warm and dry conditions. Temperatures cool and the marine layer is likely to return as onshore flow increases early next week.

DISCUSSION. as of 01:20 PM PDT Saturday . A region-wide warming trend is well underway this afternoon with temperatures currently a few to as much as 15 deg F warmer compared to 24 hours ago. Additionally, clear sky conditions prevail as the warm, dry air mass aloft has mixed well to the surface. Thus, look for widespread 80s to lower 90s for most interior locations while mid 90s are possible in the region's warmest spots. Light onshore flow near the coast will keep temperatures in the 60s to 70s there and up to the lower 80s in places such as Santa Cruz.

The ridge of high pressure over the Desert Southwest bringing this warm weather to the region will remain in place on Sunday. This should allow for mostly clear conditions overnight with just an outside chance for patchy fog near the coast and into the coastal valleys early Sunday morning. Onshore winds do increase a bit by Sunday afternoon and will keep temperatures near to slightly cooler compared to today.

Temperatures cool early next week along with a likely return of our typical summer time marine layer as an upper level trough digs into the Pacific Northwest. Medium range guidance indicates a series of short-wave disturbances rounding the base of the trough through the upcoming week. Thus, look for temperatures to reamin near to slightly below seasonal averages (especially inland) with periods of night/morning coastal clouds spreading inland into the valleys each night.

AVIATION. As of 6:50 PM PDT Saturday . For 00Z TAFs. It's VFR at all terminals. VFR is forecast at the terminals with exception of patchy fog and stratus /LIFR-IFR/ redeveloping on the immediate coastline tonight and Sunday morning. Recent guidance continues to trend toward stronger onshore wind gusts Sunday and Monday afternoon and evening. Any Sunday morning fog and/or stratus patches should mix out for VFR in the afternoon.

Vicinity of KSFO . VFR. West wind 20 gusting to 25 to 30 knots until mid evening, decreasing by late evening. Possibly stronger west wind developing Sunday afternoon and evening with gusts nearing 35 knots.

SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR, breezy onshore winds decreasing by mid evening. Patchy fog and stratus /LIFR-IFR/ returning tonight and Sunday morning. Sunday afternoon and early evening west winds 10 to 15 knots.

MARINE. as of 08:30 AM PDT Saturday . As surface high pressure builds over the eastern Pacific, northwest winds will increase across the coastal waters today and tonight. Moderate to strong winds will prevail across the waters through the holiday weekend. These winds will generate steep fresh swell resulting in hazardous seas conditions, particularly for smaller vessels. A long-period southerly swell train will persist through the weekend. This will cause occasional breaking waves over nearshore shoals and strong currents along the coast, especially near points and headlands.

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.
