What is a "Marine Zone Forecast"?
What is a "Marine Point Forecast"?

How can I get a marine forecast via zip, city, or lat/lon?

Did you know that the height of some individual waves may be twice the height of the forecast seas? And may present an even greater danger near shore?

 


NATIONAL WEATHER SERVICE PRODUCTS VIA
COMMERCIAL MARITIME COAST STATIONS and WEATHER NETS

Commercial maritime coast stations,  which provide communications services,  broadcast weather information to ships at sea as a public service, or make forecast information available on demand, either free or for a nominal fee. These transmissions are most commonly performed using HF SITOR and Pactor/E-Mail, however, several of these stations also offer service via Inmarsat satellite and other means. Within North America these include Globe Wireless , KKL Radio , ShipCom LLC (WLO/KLB), and SailMail.

There also exist a number of maritime weather "NETS" operating on commercial marine VHF, MF and HF frequencies, where weather information is exchanged. These nets are extremely popular in areas of the world which have a large yachting population and where weather is dynamic, such as in the Caribbean and typically incorporate volunteers ashore. Similar nets are conducted using Ham Radio.

Note to Net Operators - It would be helpful for nets to each establish a webpage so that we might be able to inform mariners of your activities.

Operation of a shipboard radio installation requires a license and is regulated by the FCC. The exception to this is the Telecommunications Act of 1996 which permits recreational boaters to have and use a VHF marine radio.  For further information, see the FCC's Wireless Telecommunication Bureau's Maritime Mobile Service Webpage Licensing is not normally required when receiving only.  For further information on this topic, visit the U.S. Coast Guard Maritime Telecommunications Information webpage.

Schedules and information on commercial maritime coast stations worldwide may be found in publications including NGA Publication 117 and the British Admiralty List of Radio Signals.

All NWS marine forecasts rely heavily on the Voluntary Observing Ship (VOS) program for obtaining meteorological observations.

Note:  Any reference to a commercial product or service does not imply any  endorsement by the National Weather Service as to function or suitability for your purpose or environment.
