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.
