What NOAA buoy CHII2 measures

As a NOAA meteorological station, CHII2 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 Michigan

Lake Michigan’s long north-south axis lets a sustained northerly or southerly wind build large, steep seas over its full fetch, sometimes within hours. Summer stratification is sharp and wind-driven upwelling can swing nearshore water temperature 15–20°F in a day, so watch wind direction and buoy temperatures together.
