GRIB data

GRIB is a very useful tool for the yachtsman, but it should only ever been seen as this, a tool. By downloading GRIB files you can view pressure and wind forecasts to several days ahead. Remember though, these are from the raw output of a model, without any human influence.

As forecasters we have seen occasions when GRIB forecast wind speeds can be more than 40kt less than the actual observed speeds. Caution is the watch-word. You have been warned!

There are many GRIB viewers available. Free viewers are available, or you can purchase more sophisticated, intergrated weather planner software from companies such as Global Marine Networks from whom the file below are downloaded.

If you are unsure of how to use GRIB you can come to Weather School, run by the author of this website and  where training is given on the use and limitations of using GRIB.
