Atlantic Ocean Radiofacsimile Schedule

Products listed on this page are provided by the Ocean Prediction Center. The forecast area includes the North Atlantic offshore and high seas waters. The products are transmitted via high frequency (HF) through transmitters of the United States Coast Guard from Marshfield, Massachusetts. The HF shortwave signal is decoded by Weather FAX receivers onboard ships in the forecast area. The broadcast frequencies are listed below.

NOTE: If you are interested in printing the marine weather charts listed on this page a TIFF viewer is required to have a white background. Also, the black & white GIF images are available for printing, but they are not ideally sized for printing the complete chart. The GIF marine weather charts are color enhanced and includes the actual color coded weather symbols.

Time delay of analysis products: Graphic analysis/forecast charts broadcast by radiofacsimile are available by broadcast time and are usually available 30 minutes prior to broadcast.
