PredictWind offers multiple atmospheric, wave, ocean, current and SST forecasts that update at varying times depending on when we receive the source data from the supplier.
Each global forecast model (PWG, PWE, GFS, SPIRE, UKMO, and ECMWF) is updated twice daily every 12 hours, while high-resolution regional models update more regularly.
The forecast may be 30 minutes earlier for some high-resolution locations. The times below are given in GMT. You can use this time zone converter: https://greenwichmeantime.com/time-gadgets/time-zone-converter/ to calculate the times for your location.
The next forecast update time is displayed on the PredictWind Website and PredictWind App. Details can be viewed in real-time and are written below the forecast location name.
The Schedule for each forecast is as follows:
High-Resolution Forecast Models
HRRR, NAM & AROME models
HRRR updates every hour. The 00, 06, 12, and 18z runs have a full-length forecast (48h), and the other runs are 18h. The forecast we have is assembled from the most recent run plus the last 30 hours from the prior full run. This means the cadence is not precisely 60 minutes, as the longer run comes out later. It updates at the same time every hour.
NAM updates every 12h 0300 and 1500 GMT
AROME updates 5 times a day at UTC 0000, 0300, 0600, 1200, and 1800.
Remember that the exact update times may vary slightly depending on where PredictWind receives the source data from and the ingestion process.
