What NOAA buoy 45207 measures
As a NOAA meteorological station, 45207 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 Erie
Lake Erie is the shallowest Great Lake, which makes it the fastest to turn dangerous: northwesterly winds can stack steep 4–6 ft seas in the western basin within hours, and wind-driven seiches shift water levels several feet end to end. Watch wind speed and direction closely and check the buoy in your basin.
