The weather routing is the best tool for updating your forecast along your passage. The file size is very small (only 6KB) so very quick to download. You should update the weather routing forecast every 12 hours when the forecast updates.  

The schedule for each forecast is as below:  Please add one hour if on daylight savings time.

The 1km resolution PWG forecasts are updated at 06:00 UTC and 18:00 UTC
The 1km resolution PWC forecasts are updated at 07:00 UTC and 19:00 UTC

The 8km resolution PWG forecasts are updated at 05:00 UTC and 17:00 UTC 
The 8km resolution PWC forecasts are updated at 06:30 UTC and 18:30 UTC

The 50km resolution PWG forecasts are updated at 04:45 UTC and 16:45 UTC
The 50km resolution PWC forecasts are updated at 05:45 UTC and 17:45 UTC

• You do not need to download any GRIB files for the weather routing to be calculated, as the processing is done on the PredictWind servers. 

• Select 'Weather Routing' from the left menu and move your start and destination points to your desired locations.

• Click on the 'Download' button.

• Select the Weather Routing and Departure Planning section. Make sure Weather Routing is selected.

• Click on the settings wheel.

• Change the time zone and date and adjust your polar speed if necessary. If accurate please leave on 100%

• Choose if you would like to avoid wind speeds and swell heights. The minimum for wind speed is 25 knots, and the minimum for swell height is 2.5m. We do not allow lower values, as the optimal routes can be very long, trying to avoid these conditions. When using the comfort option the optimal route can vary substantially for each forecast as it avoids these conditions.

• Click on the red 'x' button when you have finished changing your settings.

• Click 'next.'

• Click 'download all' and wait for your file to download.

• Select 'close' tab to view your Weather Route.

• You can scroll through 'Wind,' 'Route,' 'Swell,' and 'Current' tabs to view the data.

• Click 'Hide Tables' to return to your Weather Route.

Please note, the forecast will run for a maximum of 14 days. Beyond 14 days, the model forecast is not accurate.

Note: When creating routes you can add multiple waypoints to a route, by clicking on the "+" in the top right waypoint edit box. You can edit this waypoint, or click and drag on the map.
