Waves - Great Lakes makes public Great Lakes boating data easier to use before you leave the dock. Check recent wind, wave, water-temperature, and harbor observations from public sources across the Great Lakes. See a clean map of active reporting stations, a plain-language nearshore forecast, official weather and marine alerts, buoy trends, public lake cameras, and a simple departure planner.

It is not a navigation system, chartplotter, emergency service, or substitute for official forecasts, required navigation equipment, prudent seamanship, or your own judgment. Public observations can be missing, delayed, seasonal, or incorrect. Always review official NWS, NOAA, and Canadian information before leaving the dock.
