Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
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.

Area Forecast Discussion National Weather Service Hanford CA 405 AM PDT Fri Sep 25 2020
SYNOPSIS. High temperatures will be a few degrees below seasonal averages through Saturday. A warming trend will then push highs to several degrees above normal for next week. Dry weather will persist for the foreseeable future.
DISCUSSION. Temperatures have been trending slightly downward across central California for the last couple of days under a near zonal flow with weak passing shortwave impulses. This trend will continue today, with afternoon highs expected to top out around 3-7 degrees below normal. Moderate northwesterly wind gusts can also be expected By Saturday, a high pressure ridge will begin to amplify over the northeast Pacific and our flow will become more northwesterly but little change in conditions, just a degree or so of warming.
For the start of next week the strengthening Pacific ridge is progged to migrate inland over the western states and we will see a warming trend ensue. As the ridge strengthens and low level flow turns more offshore, temperatures will climb and by Monday we can expect afternoon highs as much as 4-8 degrees above climo.
Models show little change in the west coast ridge throughout next week and as a result we should see little change in conditions during the period. Blended model guidance currently shows high temperatures running around 3-7 degrees above seasonal averages.
The pattern remains dry and our forecast remains free of precipitation throughout the period. Fires in and around our area will continue to create impacts, and as the flow turns more offshore early next week, smoke from Sierra fires will be transported in a more westerly direction.
AVIATION. IFR visibilities due to smoke and haze are likely in the Sierra Nevada and adjacent foothills through at least Friday. Otherwise, VFR conditions will prevail through at least the next 24 hours.

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.
