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... Northwest winds will increase this afternoon through Wednesday night as a low pressure system moves inland over the pacific northwest. The waters off the big sur coast will likely see some gale-force winds and/or gusts. Additionally, can't rule out some isolated gale-force gusts for the outer waters north of point pinos. Mixed swell will persist with a moderate northwest swell and a light southwesterly swell.

Area Forecast Discussion National Weather Service San Francisco Bay Area Issued by National Weather Service Los Angeles/Oxnard CA 1031 AM PDT Tue Mar 31 2020
SYNOPSIS. Dry weather conditions with seasonable temperatures are forecast for the remainder of the week. Rain chances and cooler temperatures return by the upcoming weekend and will potentially continue into early next week.
DISCUSSION. as of 09:15 AM PDT Tuesday . A cloudy start to the day for the North Bay along with possibly a few light showers should give way to at least partly sunny conditions by the afternoon. Farther south plenty of sunshine and warmer temps than yesterday.
PREV DISCUSSION. as of 02:58 AM PDT Tuesday . An upper level low off of the British Columbia coast and associated trough extending into the Pacific Northwest continues to produce widespread cloud cover and isolated showers over northern California. With this, cannot rule out so very light precipitation over far northern portions of the North Bay today, mainly across northern Sonoma County. Elsewhere, dry weather conditions are likely today under a partly to mostly sunny sky. Temperatures will generally warm into the upper 50s along the immediate cost while 60s are likely inland.
Dry weather conditions are likely to persist through the remainder of the week as the storm track stays to the north. Additionally, temperatures will remain near to slightly below seasonal averages in response to a broad trough over the much of the western portion of the country. Overnight/morning temperatures will coo slightly by midweek as a slightly drier air mass filters into the region. This may allow for some inland valley locations to drop into the middle 30s by early Thursday and Friday mornings.
Surface high pressure will build over the eastern Pacific resulting in gusty northwest winds over the Pacific and near the coast from late today through Wednesday evening. However, wind speeds inland will generally remain light.
Deterministic models and ensembles continue to indicate the return to unsettled weather conditions by late this week (generally late Friday) and into the upcoming weekend. However, there remain some differences in model-to-model solutions with respect to timing and position of the mid/upper level trough. Regardless, look for a cooling trend and increased precipitation chances region-wide as we head into the upcoming weekend. Conditions potentially remain unsettled heading into early next week as well.
AVIATION. as of 10:30 AM PDT Tuesday . Visible satellite shows a mix of MVFR and VFR ceilings across Bay Area terminals this morning. Expect these ceilings to mix out this afternoon with mostly clear skies for all sites this afternoon. For tonight, expect mostly clear skies to continue. Onshore winds are expected this afternoon and evening.
Vicinity of KSFO . MVFR ceilings will persist through 19-20Z, then VFR conditions are anticipated this afternoon and tonight. Westerly winds 10-15 knots will develop this afternoon and continue through this evening.
SFO Bridge Approach . Current low clouds should dissipate early this afternoon with conditions similar to the terminal forecast.
Monterey Bay Terminals . VFR conditions are anticipated through TAF period. West to northwest winds expected this afternoon and evening.
MARINE. as of 10:15 AM PDT Tuesday . Northwest winds will increase this afternoon through Wednesday night as a low pressure system moves inland over the Pacific Northwest. The waters off the Big Sur coast will likely see some gale-force winds and/or gusts. Additionally, can't rule out some isolated gale-force gusts for the outer waters north of Point Pinos. Mixed swell will persist with a moderate northwest swell and a light southwesterly swell.

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. |
