NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. NWR broadcasts official Weather Service warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week.

NOAA's Web Mapping Portal to Real-Time Coastal Observations, Forecasts, and Warnings. nowCOAST™ provides situational awareness on present and future environmental conditions for coastal and marine users by integrating data and information from across NOAA, other federal agencies and regional ocean and weather observing systems. For example, users can assess present conditions by creating maps of the latest in-situ weather/marine weather observations, weather radar reflectivity mosaics, cloud images from satellites, surface wind and sea-surface temperature analyses, and precipitation amounts for the last few hours. In terms of future conditions, users can obtain maps of critical weather and marine weather advisories, watches, and warnings, weather forecasts, tropical cyclone track and intensity forecasts, and forecast guidance of water levels, temperature, salinity, and currents from oceanographic forecast models. In addition, nowCOAST™ provides users with thousands of geo-referenced hyperlinks to observations, forecasts, forecast guidance, and forecast discussions located on web pages operated by NOAA and other federal agencies to obtain more detailed data and information

Marine forecast offices, marine & coastal weather services, marine forecasts, observations and more from the National Weather Service.

The OPC strives to provide the world's best marine weather forecasts, preventing loss of life and property at sea. It an integral component of the National Centers for Environmental Prediction (NCEP) located at the National Center for Weather and Climate Prediction in College Park, Maryland. OPC originates and issues marine warnings and forecasts, continually monitors and analyzes maritime data, and provides guidance of marine atmospheric variables for purposes of protection of life and property, safety at sea, and enhancement of economic opportunity. These products fulfill U.S. responsibilities with the World Meteorological Organization and Safety of Life at Sea Convention (SOLAS). OPC also provides forecast points in coordination with the National Hurricane Center (NHC) for Tropical Cyclones in the Atlantic Ocean E of 60W and N of 20N. In emergency situations OPC acts as a backup to the National Hurricane Center (NHC) and the Honolulu National Weather Service Office taking over the marine functions. Those offices also act as backups to OPC's marine functions.

Since its formation in 1977, the company had been fully engaged with support divided between the private and public sector. In the public sector the company continues to perform basic and applied research in marine meteorology and ocean response numerical modeling, supported by both US and foreign government agencies.

PassageWeather was developed out of the need for accurate, reliable and easy to use weather information and forecasts. We provide 7-day Wind, Wave and Weather Forecasts to help sailors with their passage planning and weather routing. Both before and during deliveries, ocean races, regattas, cruises and all other types of offshore passages, we have your whole route covered. The weather data that we use to produce our weather forecast charts come from the most trusted and reliable sources available. These sources include the US National Weather Service (NWS), the National Oceanic and Atmospheric Administration (NOAA), the National Centers for Environmental Prediction (NCEP), the Marine Meteorology Division of the U.S. Naval Research Laboratory (NRL), Frivind AS and the Cyprus Oceanography Center.

This website was founded in 2000 mainly as a convenient way to access weather sources that we use ourselves regularly. It was soon discovered however by thousands of sailors on both sides of the Atlantic. We used the occasion of our 10th anniversary for a major update both in layout and content. This new website does not only reflects our own ideas about useful weather information but also the many suggestions we got from various users. Sailing Weather Online is based in the Netherlands.

Monitoring and being kept advised of current and forecast weather conditions is an essential part of every mariner's responsibility. Weather Routing Incorporated (WRI), Ltd. now provides one online weather center to find all your weather products. From real-time surface observations to satellite data to local warnings, Weather Routing's SeaWeather.net is your one stop source.

We think every mariner should use high-resolution weather forecasts, it's a critical aspect of safety at sea and it's not just for the professionals. We produce our forecasts using the WRF/NMM, the very same model used by the U.S. met office, NOAA, to produce their high resolution data over the U.S. - London, England

On any given day, volunteer crew members on nearly 1,000 ships around the world observe the weather at their location, encode each observation in a standard format, and send the data over satellite or radio to the many national meteorological services that have responsibility for marine weather forecasts.

Welcome to the U.S. Voluntary Observing Ship (VOS) Program web site. Here, you will find general information about the worldwide VOS Programme, contact information for U.S. VOS Program Mangers and Port Meteorological Officers, instructions for making and sending weather observations, web version of the Mariners Weather Log, and links to other projects and efforts related to VOS. On any given day, volunteer crew members on nearly 1,000 ships around the world observe the weather at their location, encode each observation in a standard format, and send the data over satellite or radio to the many national meteorological services that have responsibility for marine weather forecasts. This data is archived for future use by climatologists and other scientists. The United States VOS Program services about one quarter of the world's VOS fleet, providing ships' crews with weather observer training, handbooks and forms, observation encoding software, barometer calibration, the Mariners Weather Log, and weather observing tools. Located in the major ports around the country, Port Meteorological Officers are the VOS Program's field representatives and primary points of contact for ships.
