Weather Routing

Find the quickest or safest route through the wind and waves, and view the wind conditions along the entire route. Trust the world's best cloud based weather routing service for your next adventure.

Accurate Weather

Every PredictWind route is calculated using the highest resolution ECMWF/SPIRE/UKMO/GFS/PWG/PWE forecast data. ECMWF is proven to be the most accurate global weather model from a National Weather Centre, however the Spire model actually beats the ECMWF forecast accuracy in offshore passages. The high resolution PredictWind models that are run at 1km/8km resolution are the highest resolution models available with proven accuracy in the short term. Getting 6 forecasts for every route gives you additional confidence in the forecast.

Speed & Ease

As the PredictWind router is run on cloud computing off the boat, it is not essential to download GRIB files to calculate a route, and in some circumstances this will save you at least 50 MB of GRIB downloads. The PredictWind router has access to the highest resolution GRIB data for wind, wave and current. To download this data on a mobile or satellite connection is very slow and expensive. With the click of a button, the forecast information, including routes for all 6 forecasts are quickly and easily displayed to help make informed decisions.

Long Range Forecasts

We have added the ECMWF ensemble forecasts with an incredible long-range 4-week forecast. The ECMWF ensemble is unequivocally the leader in long range forecasting, and will let you plan your trip well in advance, with better accuracy than traditional climate forecasts.


The PredictWind router simply works. No failed routes, or issues with the router crossing land or shallow water, so you can concentrate on sailing the boat, rather than troubleshooting why the router did not work. Check the technical report for the reliability of the new PredictWind Router.
