I just learned that you can now text buoys out in the Great Lakes. This is actually pretty awesome, especially for any one taking out a boat. The phone number to text is 866-218-9973 each buoy has its own code that you text to the 866 number, what you get in reply is: Date, Time, Wind Speed & Direction, Wind Gust Speed, Air Temperature, Water Temperature, Wave Height, and Wave Interval.
If you look at a screen shot of the Current Buoy Map (Oct 2019) it looks like a pretty extensive network.
There is a website with a list of all the buoys, showing you the reference code that corresponds to each buoy. .https://glbuoys.glos.us/
