Ontonagon Marina is a public boat ramp in Ontonagon County, Michigan, on Ontonagon River. From here SeaStatus scores 3 waters: Black River To Ontonagon MI, Lake Superior from Saxon Harbor WI to Upper Entrance to Portage Canal MI 5NM off shore to the US/Canadian border including Isle Royale National Park (Area 5 of 7) and Ontonagon to Upper Entrance of Portage Canal MI.
The main water here is Black River To Ontonagon MI. Nearshore water is scored mostly on wind and wave height, with wave steepness and the tidal current counting too. A current running against the wind is treated as worse than either one alone. Wind, and waves where it reports them, come from NDBC buoy 45216, and tide predictions come from NOAA station 9099044. Its conditions are read at a reference point on the water about 18.6 mi from this ramp.
Scores are decision support, not a substitute for your own judgment or the official NWS forecast. Read the limits.
