Funny this was mentioned, I have been thinking on adding something like this to the DFX skin over the past weeks... This just gave me an excuse to put something together
I put together an exe that will scrape a web page, and put the info into variables in RR. I did the skins and all for the DFX skin, and have also attached a copy of the .exe here for use with other skins.
The variables are done in rows and columns. the first digit is the row, and the second is the column for putting the variables into a skin.
It works 2 ways, by default if you just run the .exe, it will get the tidal information based on your GPS location in RR. You can also pass a zipcode to it on the command line, to view tidal information for any zip code in the US.
NOTE: Unfortunately, I can not seem to find a page to get this information other than in the US.
Below are the download, and a screen cap of the information in the DFX Skin:
