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.
  • WFO Honolulu, HI
    North Pacific surface weather south 30N to 30S between 130E and 110W.
  • National Hurricane Center (NHC)
    Tropical Cyclone forecasts for the North Atlantic and North Pacific Oceans which includes the eastern Pacific east of 140W.
  • Central Pacific Hurricane Center (CPHC)

  • U.S. Voluntary Observing Ship (VOS) Project
    The U.S. Voluntary Observing Ship (VOS) Project web site below provides general information about the worldwide VOS Programme, contact information for U.S. VOS Project Managers and Port Meteorological Officers, instructions for making and sending weather observations, web efforts related to VOS. Click for some great information on where the NWS/OPC marine weather warnings, analyses, and forecasts products and services gets started!
  • 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. 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 click on the small red dot that is the Seattle forecast office in Western Washington State. On the left hand side of the home page, click on “marine” under the FORECAST portion of the menu.
