GRIB Model

OFS Gulf of Maine Currents

Provider:Center for Operational Oceanographic Products (NOAA)
Model scope:North America East Coast
Update frequency:every 6 hours
Resolution:0.6nm, 1.1km
Model duration:24 forecasts starting at 3 hrs, ending at 3 days
Parameters:current, tide
GRIB model date:Mon Jul 15 00:00:00 2024 UTC
Download date:Mon Jul 15 03:18:37 2024 UTC
Download delay:3hr 18min

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.


The Operational Forecast System (OFS) series of models is run by the National Ocean Service (NOS) and the National Weather Service’s (NWS), both a part of the National Oceanic and Atmospheric Administration (NOAA).

The Gulf of Maine OFS model is calculated using a bathymetry following irregular grid which has over 800,000 grid nodes. The results of this computation are then sampled, by OFS, into a regular latitude / longitude aligned grid. This data on this regular grid are then converted to GRIB format by LuckGrib.

Note: This data is only available with forecast data every three hours. There are extreme tidal flows in this model domain, and the highs and lows of the actual currents may not be captured in the GRIB data. You should exercise caution when using this data, and be sure to consult official tide and current references.
