Synopsis..Strong high pressure will build in and remain over the region through the end of the week and into the upcoming holiday weekend with mainly rain free conditions and hot temperatures. East southeast winds will prevail except becoming onshore along the coast during the afternoon. A subtle increase in the easterly flow is expected during Thursday and Friday which will keep the west coast sea breeze close to the coast. The increase in winds will also lead to and easterly surge which will support winds approaching cautionary levels during the evening and overnight hours, especially across the offshore waters. Lighter winds will return for the weekend as the high sinks south over the area.

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.
