The world’s best global models

PredictWind’s goal is to deliver the most accurate forecast data available. Having access to the world’s top forecast models enables users to be assured of the best possible forecast. With the top-ranked global models, along with the high-resolution PredictWind modeling and the best regional models, PredictWind offers unparalleled forecast accuracy.

ECMWF
The European Centre for Medium-Range Weather Forecasts model is highly regarded by meteorologists around the world. ECMWF’s HRES model consistently rates as the top global weather model and offers a record breaking 9km resolution. This data has a very high acquisition cost, and is not available to most weather providers.
  • Resolution: 9km
  • Range: 10 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
SPIRE
Spire’s satellite constellation uses radio frequency sensors to create a 3D profile of atmospheric temperature, pressure, and humidity over 10,000 times per day. Spire outputs a global resolution of 12km with an advantage in forecast accuracy for remote locations.
  • Resolution: 12km
  • Range: 10 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
UKMO
The UK Meteorological Office UKMO model, is used by many Met Offices and weather companies around the world. UKMO has a 15km resolution model output and studies show that it is on par with ECMWF model for offshore forecasts, and slightly behind the ECMWF & Spire models for land-based forecasts.
  • Resolution: 15km
  • Range: 7 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
GFS
The Global Forecast System model from NCEP is the most widely used data source as it is free of cost. Whilst it is a good model, it has a lower accuracy score than the models above. GFS runs at a 13km resolution, but is only output at 27km globally.
  • Resolution: 25km
  • Range: 10 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
PWE
PredictWind creates two exclusive global models. The first is PWE, which uses the ECMWF global initial conditions for the model run. It offers exceptional short term accuracy.
  • Resolution: 8km
  • Range: 7 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
PWG
PWG is PredictWind’s second exclusive global model, which uses the NCEP (GFS) global initial conditions for the model run. As with PWE, the PWG model offers exceptional short term accuracy.
  • Resolution: 8km
  • Range: 7 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly

High-resolution regional models

Our regional models provide short range, high resolution forecasts for selected regions around the world. Find out what resolutions are available in your area by viewing our Global Coverage

PWG 1km
Our exclusive PWG high resolution model uses the NCEP (GFS) global initial conditions for the model run. PWG offers exceptional short term accuracy and a record breaking resolution of 1km, capable of displaying land and thermal effects.

  • Resolution: 1km
  • Range: 1.5 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
PWE 1km
Our exclusive PWE high resolution model uses the ECMWF global initial conditions for the model run. PWE offers exceptional short term accuracy and a record breaking resolution of 1km, capable of displaying land and thermal effects.

  • Resolution: 1km
  • Range: 1.5 Days
  • Time step: 1 Hour
  • Update frequency: 12 Hourly
NAM
NAM is one of NOAA’s major weather models, covering most of North America. NAM is a mesoscale model, capable of modelling land and other features at a higher resolution than global models, leading to improved forecast accuracy.
  • Resolution: 5km
  • Range: 84 Hours
  • Time step: 1 Hour
  • Update frequency: 6 Hourly
HRRR
HRRR by NOAA is a real-time model covering the USA with a resolution of 3km. The model is updated hourly and is supplimented with radar data assimilation every 15 minutes, refining the forecast for even greater accuracy.
  • Resolution: 3km
  • Range: 18 hours
  • Time step: 1 Hour
  • Update frequency: Hourly
AROME
Arome by Meteo-France was designed to improve short range forecasts of severe events across Europe, such as severe storms, fog and urban waves. It outputs a resolution of 1.25km and is highly regarded by top racing navigators as it beats the ECMWF forecast.
  • Resolution: 1.25km
  • Range: 42 Hours
  • Time step: 1 Hour
  • Update frequency: 00z, 03z, 06z, 12z, 18z

Optimised for Satellite Connections

Passage weather offers a mobile website/low bandwidth for users on slow internet connections. However, this site only provides weather images (still quite large), rather than highly compressed GRIB data, which is a fraction of the file size. GRIB data from PredictWind can be viewed in the free PredictWind GRIB viewer available on PC/Mac/iOS/Android devices.

Direct Downloads for ease of use

The PredictWind GRIB viewer has full integration with most satellite systems on the market to allow seamless download and display of the weather data. It is not practical to view a low bandwidth website on a low-speed Satellite phone connection.
