NOAAPORT - Realtime Great Lakes Weather Data and Marine Observations

This page contains realtime marine data from Great Lakes buoys, coastal met stations, airports, and ships. The data are transmitted through the NOAAPORT system and are received continuously at NOAA/GLERL via satellite dish. Marine obs include wind speed, wind gust, wind direction, air temperature, dew point, cloud cover, sea level pressure, water temperature, wave height, wave period, and live tracking of Great Lakes ship locations.

Most recent observation: 00:16 GMT, DOY 255, 2024 (Sep 11, 2024)
This page is updated hourly at approx. 18 minutes past the hour
