Marine Point Forecasts are a forecast for a specific point. Also provided on the point forecast pages are the "Forecast at a Glance" feature, and links to the "Hourly Weather Graph" and other data of local interest

Not yet available and/or may only be available experimentally in the areas of Alaska, Micronesia, Samoa, offshore, high seas, Canada, etc.....(a zone forecast may be returned in some of these cases...a zone forecast may also be returned when point data is temporarily unavailable)

 

A National Weather Service "Marine Point Forecast" refers to a text forecast for a single point generated from a forecaster-generated gridded data set known as the National Digital Forecast Database (NDFD) also used to produce graphics. The NDFD is used as the basis for the majority of local public and marine forecasts and is in the process of being further expanded to the offshore and high seas areas.

In actuality, the "point" is a single small rectangle which represents the resolution of the computer forecast models which is typically 2.5 by 2.5 kilometers.

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. Be aware, the forecast conditions at a particular point may not exceed the criteria of a Small Craft Advisory, Gale, Storm etc. These watches/warnings/advisories are issued for the entire zone in which the point resides and mariners should act accordingly.

The map interface and web form above may also be used to obtain point forecasts for land.
