Great Lakes Wave Heights
 

Does anyone know where to get wave height info for specific dates? Great Lakes Buoys used to let you enter dates. But, they updated the site and now it's not an option.

NDBC - Historical NDBC Data

if you ever boat out of st joe Michigan there is a web cam that faces the light house and give you a good idea of wave height...google lake Michigan conditions and it should pop up...not sure what great lake you were wanting but its a good tool I use...otherwise under that search you can also go to a site that lists all of lake michigans ports and gives you wave heights etc. (weather underground its called)
