Every day on the water can't have balmy breezes, abundant sunshine and consistently warm weather; however, staying out of bad weather is relatively easy if you plan ahead. The National Weather Service (NWS) provides mariners with continuous broadcasts of weather warnings, forecasts, radar reports and buoy reports over VHF-FM and Single Side Band (SSB) radio. There are almost no areas on the Atlantic ICW where a good quality, fixed-mount VHF cannot pick up one or more coastal VHF broadcasts. Also, there is no substitute for simply looking at the sky, and either stay put or seek shelter if you don't like what you see.

SSB Offshore Weather

SSB reports are broadcast from station NMN in Chesapeake, VA, and from station NMG in New Orleans, LA. The broadcasts are not continuous, so refer to the latest schedules and frequency lists (provided below) to catch them. SSB reports provide the best source of voice offshore weather information. Two major broadcasts alternate throughout the day. The High Seas Forecast provides information for mariners well offshore, including those crossing the North Atlantic Ocean. Coastal cruisers will be more interested in the Offshore Forecast, which includes information on waters more than 50 miles from shore. The forecast is divided into regions:
