Great Lakes Current Marine Weather Observations

Dial-A-Buoy Great Lakes

Dial-A-Buoy provides the mariner with an easy to use system to receive current weather information for the Great Lakes area. The system is accessed through a toll free phone number allowing the mariner to gather up to date weather information any time and anywhere they can make a phone call.

The Station List

The tables below list the weather coast stations and buoys of the Great Lakes. We have broken them down by geographic area (individual lakes) to assist in locating the stations of importance to you. We have also converted the mixed character and number station id’s to their numeric equivalent to aid in dialing in the correct number.

Here are quick links to the major sections of this page:

We have started at Lake Superior and continued south and east to Lake Ontario.

While not every station has been included, the list is comprehensive enough to provide very good coverage. If any errors are noted or if you would like to see a particular station included that we have left out, please e-mail us with your requests, corrections, or recommendations.
