High pressure will remain over the region through early next week, with light south to southeast winds shifting onshore near the coast each afternoon due to the seabreeze. During this timeframe, the only marine concern will be locally gusty winds and rough seas due to scattered marine Thunderstorms during the late afternoon and evening hours.

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.
