Ohio marine forecasts: common questions

Is there a small craft advisory off Ohio right now?

3 of the 16 Ohio marine zones are under an active advisory or warning, Conneaut OH to Ripley (small craft advisory), Geneva-on-the-Lake to Conneaut (small craft advisory) and Willowick to Geneva-on-the Lake (small craft advisory). Each zone page shows the expiry time and the full text.

How windy is it on the Ohio coast right now?

Buoys off Ohio are reporting 2 to 18 knots, the strongest at Reno Beach to The Islands OH (beyond 5 nm). A knot is 1.15 mph, so 20 knots is about 23 mph. Wind measured offshore is usually stronger than the same wind felt in a harbor.

How rough are the seas off Ohio today?

The highest seas measured right now are 4 ft off Conneaut OH to Ripley, out of the 16 of 16 Ohio zones with a wave-capable buoy nearby. Seas are significant wave height, the average of the highest third of the waves, so individual waves run noticeably higher than the figure.

Who issues the marine forecast for Ohio?

The National Weather Service, from its Cleveland, OH office. Each of the 16 zones on this page gets its own bulletin in a legacy teletype format, reproduced here in full underneath the charts and the live buoy readings.
