12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

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 Sacramento CA 200 PM PDT Sat Jul 4 2020
SYNOPSIS. Dry weather with seasonable temperatures for the next week.
DISCUSSION. Sunny skies and mostly seasonably warm temperatures will continue across interior NorCal through next week. Temperatures this holiday weekend will be around 5 to 10 degrees warmer than the previous few days as the South West high moves west and raises heights aloft over NorCal. Early afternoon temperatures are around 5 to 15 degrees warmer than this time yesterday and are expected to peak in the upper 90s across the Valley and 70s to 80s in the mountains. Similar temperatures are expected tomorrow.
Ensembles continue to indicate an upper level trough slowly deepening over California early next week. This will allow temperatures to cool a few degrees back to normal or slightly below normal. Onshore flow will return as well, and a shortwave moving through NorCal on Monday looks to bring gusty south to west winds, especially through the Delta and over higher elevations. Tuesday winds will be gusty as well, though not as strong as Monday. Fire weather concerns are low with these winds as humidities will be increasing somewhat because of the onshore flow. However, grasses are cured in the Valley and lower foothills, so fire safety should always be practiced during this time of year. HEC
EXTENDED DISCUSSION (Wednesday THROUGH Saturday). Ensemble means continue strong ridging over the central CONUS while maintaining a weak trough along the West Coast later next week. Dry weather with temperatures close to average is expected to persist.
AVIATION. VFR conditions continue the next 24 hours. Winds remain under 10 knots except in the Delta where gusts up to 20 knots will be possible from 22z to 12z.
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. |
