GRIB Model

RTOFS Global HYCOM - Ocean Currents

Provider:National Centers for Environmental Prediction, NOAA (USA)
Model scope:Global
Update frequency:every 24 hours
Resolution:0.083°, 5.0nm, 9.3km
Model duration:5 forecasts starting at 12 hrs, ending at 4 days 12 hrs
Parameters:current, water temperature
GRIB model date:Sat Sep 21 00:00:00 2019 UTC
Download date:Sat Sep 21 16:33:56 2019 UTC
Download delay:16hr 33min

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.


This model provides forecasts for global ocean currents, at a high resolution.

The global operational Real-Time Ocean Forecast System (Global RTOFS) at the National Centers for Environmental Prediction is based on an eddy resolving 1/12° global HYCOM (HYbrid Coordinates Ocean Model) …

If you are interested in the Gulf Stream, you should also consider the US-East Coast NCOM model.. Sailors in the Caribbean will also have access to NCOM Caribbean.

This model is refreshed at around 16:00 UTC every day.
