Get real-time marine observations from ocean buoys and coastal (C-MAN) stations around the US coasts, the Gulf, the Great Lakes, Hawaii, Alaska and the open Pacific and Atlantic: significant wave height, dominant and average wave period, wave direction, wind speed, direction and gusts, sea-level pressure, air and water temperature, dew point and visibility — as clean JSON rows. Ask for the latest reading from every station, only the stations near a point, or up to 45 days of history for chosen stations. Built on the published data files of the National Data Buoy Center. Useful for surf and sailing apps, fishing and boating, shipping and offshore operations, coastal research, insurance and energy dashboards and AI agents.
