Quickly see marine forecast data for all of the Great Lakes.
Quickly see forecast data for up to the next 120 hours for Lake Superior, Lake Michigan, Lake Erie, Lake Huron, Lake Ontario, and Lake St. Clair. Some of the data sets you can view are wind speed, wave height, air temperatures, surface water temperatures, cloud cover, currents, and many more. Besides forecast data, you can view "Nowcast" data for up to the past 48 hours for things like wind speed, wave heights, temperature transects, temperature profiles, and more. All data sets are presented in easy to understand maps of all the lakes and can be viewed as individual slices in time or as animated maps.
