Point ForecastPoint Forecasts are for the specific location entered. The area covered is about the size of San Francisco Airport so it is very specific to the point you pick. The initial point will be the point you picked on the map, or the point picked through your entry of location if you did not click the map, in page setup or change location. That point determined the setup of the entire page. Editing the Point Forecast from its edit menu will only change the location of the Point Forecast.
The icons above show the sky condition for the day or night. Conditions shows cover 4PM and 4AM but in general are similar for the day. The numbers in the lower right corner are the probabilities of precipitation. The forecast covers 7 days. The graph below shows the wind forecast, gusts, and wind direction for the full 7 days. More detail is shown for the earlier days. The arrows align with the wind flow so a southerly wind will have an arrow that points north. The directions are listed so there will be no confusion.
Clicking on the underlined "Point Forecast" in the title bar will take you to the NOAA site for that point where you will see a 5 day forecast and other options that you might want to check out.
To refine or change the location of just the point forecast section, click EDIT. That will present a map and clicking on it will change the location.
If you would like to see two point forecasts, click on the map twice. This is useful if you are planning on sailing from one location to another and want to see the weather and wind forecast for both locations as shown below.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. 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.
