Marine Weather Links

Public Marine-Weather Websites
Let’s initially focus on specific web pages which are a direct interest to mariners.  Starting with “Rome” for your marine weather, the Ocean Prediction Center (OPC):

  • Ocean Prediction Center (OPC)
    Located in Camp Springs, MD, “Rome”, or OPC, should be a mariners first choice for marine weather resources! OPC provides a complete graphics, text, and voice broadcasts suite of marine weather products for the entire North Atlantic and Pacific Oceans north of 30N. From the OPC web site, one can link to other National Weather Service (NWS) marine weather forecasts sites, including international resources as well.
  • Tropical Analysis and Forecast Branch (TAFB)
    North Atlantic marine weather south of 30N cover the Tropical North Altantic Ocean, Gulf of Mexico, and the Carribbean Sea. Also, includes the North Pacific south 30N and east of 140W and including portions of the southern hemisphere to 25S.

  • The National Weather Service (NWS) Marine program
    This is the NWS US marine weather home page which also overlaps and covers both OPC, TAFB, and NHC under the National Centers for Environmental Prediction or NCEP (see next page for specific details on NWS structure and administration). Both the specialized national center perspective and the local line NWS field forecast office perspective, define the US marine forecast program.For example: if one is interested in marine forecasts from Seattle, WA, go to the above link and note the map of the US. Click on the map and note that it will expand. Concentrating on the red dots where line field offices have local marine warning and forecast responsibilities, such as NWSFO Seattle noted above… Click on the small red dot that is the Seattle forecast office in Western Washington State.
