What NOAA buoy CWCI measures
As a NOAA meteorological station, CWCI 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.
