What NOAA buoy LPNM4 measures

As a NOAA meteorological station, LPNM4 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 Huron

Lake Huron pairs a big open main basin with the sheltered waters of Georgian Bay and the North Channel, so conditions vary a lot with where you are. The open lake builds steep, short-period seas on a sustained blow — check the buoy nearest your water and mind the wind direction.
