NOAA station 45217, Wisconsin Point, reports real-time marine conditions from 46.708°N, 92.000°W in Lake Superior. Readings refresh roughly every 10 minutes, and Big Buoy adds a solunar table and a multi-day weather outlook for the area.
What NOAA buoy 45217 measures
As a NOAA meteorological station, 45217 reports wind speed, gusts and direction, barometric pressure, air and water temperature, and — where wave sensors are fitted — significant wave height, swell period, and wave direction.
What to watch in Lake Superior
Lake Superior is the coldest, deepest, and largest of the Great Lakes, with enough open water and fetch to build true offshore seas. Water stays cold most of the year and storms move through fast, so a sustained blow can raise steep, short-period waves with little warning — read wind, fetch, and sea state together before heading out.
