- For safety concerns, mariners should be aware of the weather over a larger area. Forecast information for a larger area can be found within the zone forecast and the NDFD graphics. The forecast conditions at a particular point may not exceed the criteria of a Small Craft Advisory, Gale, Storm etc.

This forecast is for a single location. For safety concerns, mariners should be aware of the weather over a larger area. Forecast information for a larger area can be found within the zone forecast and the NDFD graphics .
Please Note: Being a forecast for a single point, the point forecast is very specific and mariners should also be aware of weather conditions in the surrounding area. Forecast information for the surrounding area can be found within the zone forecast and the NDFD graphics .
This is often not a problem for mariners, as conditions can be similar over large areas. However, when a slow moving frontal boundary slices through a zone, there can be large differences in winds, seas and weather. Conditions can also be vastly different when navigating in the Gulf Stream.

When we think about early humans and sailing, we mostly wonder how they navigated their vessels without the aid of maps. But one critical aspect of sailing is the weather. Since ancient sailors couldn’t yet predict the weather or understand the science behind it, how were they able to sail successfully? The answer is they weren’t often successful a...
People from all cultures had their own versions of predicting the weather. But it wasn’t until the masters like Copernicus and Galileo delved into the science of astronomy that people began to have a better idea of atmospheric science. But neither of these scientists could accurately predict the weather, and, if they could, they could not convey th...
As science and marine travel moved into the 20th century, atmospheric scientists made great strides to improve the way the marine forecast was estimated and delivered. Not only did communication techniques improve, but new ways to observe weather patterns also allowed people to better understand major storm systems and their behavior.
Communication between NOAA and other marine monitoring agencies is done with specific nautical terminology. Without knowledge of these terms, sailors may not understand the potential hazards looming on the horizon.
Modern sailors have a wealth of weather information at their fingertips. The World Meteorological Organization has been instrumental in gathering weather data and making it available to anyone engaged in water activities. Primarily using satellite data, nautical buoys, and GPS technology, information regarding all of these weather hazards and warni...
Whether you’re a pleasure boater or the captain of a Capesize or Panamax cargo ship, the marine forecast is crucial to keeping your crew and your cargo safe from harm. Taking classes is a great way to learn the terminology and nuances of marine weather and how to navigate safely in stormy seas. Are you interested in learning more about life and wor...
These forecasts are very specific and typically limited to an area of around 2.5 km by 2.5 km, and mariners should also be aware of the weather conditions in the surrounding area. Point forecasts are generated by the National Digital Forecast Database (NDFD) , a suite of gridded forecasts of several weather elements.
Visibility between 2 and 5 nautical miles. Good. Visibility more than 5 nautical miles. Similarly, when indicating the Sea State, the range used by weather forecasts is between smooth and phenomenal. This is what they actually mean: Smooth. Wave height less than 0.5m. Slight. Wave height of 0.5 to 1.25m.
A warning alerts mariners that a significant or hazardous weather event is likely, imminent, or occurring, and is a threat to life and property. The NWS also issues weather statements to provide mariners with details on significant or potentially hazardous conditions not otherwise covered in existing marine warnings and forecasts as well as ...
