General Help

There are 10 sections to this Tide and Weather site. Each section is divided by a thick black horizontal line. Every section as one or more of these options:
  • EDIT - A link to a page to change the section specific settings
  • (on/off) - a toggle to choose if the section contents should be displayed or not
  • Links - underlined text are links to more detail or the source of the data.
  • Help - link to a help page for the section (coming soon)

Change Location

To change the overall location for the page, click on "Change Location" on the top left of the page. To change just the location of the airport, click EDIT in the Airport Report section. You will be shown a drop down list of all the airports within 200 miles. Just select whichever one you want and click submit.

Current Conditions

The Airport Report is comprised of two sections. The first gives the most up to date report of wind and weather for the airport. These are updated once an hour. The age of the report is listed in the title for the conditions report.

Wind History

The three day (72 hour) wind history is shown for your airport. They are arranged in 3 rows of 24 hours. This allows you to look down any column and see when the wind picked up, or died down, over the last few days. This is useful in planning when you might expect the wind to change in the next few hours..


The link Current Conditions will take you to the airports web site where you can see the same information that is on this page. The page buffers the data so if it looks like the data may be old on the page, click the link and see. The Wind History link takes you to the NOAA wind history page. The data on the wind history is after a couple of hours old so don't expect it to have the current conditions wind report in it. Often there will be an hour between the current conditions and the history that is missing. That is normal.

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 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 numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
