Offline use of Windy
-
To all the sailors, boaters and cruisers, mountaineers and just all of you who like Windy and repeatedly ask for the possibility to use it offline via downloading data files:
It is not possible to download the forecast data for offline use.
We do not own the data, we ‘only’ visualise it, so if we were giving it away as GRIB files, we would break the licensing agreements with our data providers.
Although we know that making screenshots (in advance) is not a perfect solution, it is the best of what's available.
Thank you for understanding and stay tuned to Windy whenever possible! :)

Maybe add a “save screen shot” button and another link to view screen shots created by the app.

Hi Marie,
Thank you for making this clear.
My question then is how companies like Predict Wind manage to do this?
We usually download Grib files through a satellite request sent to 'query@saildocs.com'.
They send the data back in package file which we then display in ZY Grib or similar.Is there no way we can have a Windy Platform to display grib data we retrieve?
I am thinking that Windy must be receiving data to generate the display we are seeing - right - so if windy created the app, and steered us to the data request source /s then we effectively could have an off shore windy app?
Thank you for the amazing Windy platform
Kind regards
Brent Grimbeek

All GRIB files that you can received via several web app that you mentioned are GFS files which are free. Some of them offer ECMWF GRIB files but you must subscribe monthly payements.

Can you negotiate with your providers to offer this feature?
In the modern world, in order to visualise data you need to transform it. If instead of sharing the source files you share the transformed data you would be respecting the agreement, wouldn't be?

Hi,
Would you be able to find a workaround for this issue?
For example a "Print Report" option that generates a PDF that we can use after we lost connection.
This is a common feature in websites like Met Office.
In that way you won't be exporting the data but "visualising" it on "paper" (PDF).
It should to be a work around... At the moment the only option are screenshots or printing the forecast before leaving home...

Hi,
For me the best way is to keep the forecast in a small video. There are many « Screen recorder » which are available. On iPad and iPhone this is a standard feature that I use sometime.
You just need to activate the time slider to get a 10 days-video forecast. Only 1 file per layer. If you need the forecasts of 3 different layers e.g. Wind, Gusts, Rain, then you have only 3 files in memory.
Looking to the forecast offline, you can stop the video where you need to analyse the details.

The liscencing issue only applies to ECMWF. All model output produced by USA agencies is public domain (free to use, no liscencing). So Windy could work with GRIB output from GFS with no issues. Windy already supports use of GFS so this should be a relatively straight forward implementation.
Implementing GRIB viewing capability in Windy would be a powerful addition. End users could download their own GRIBs, from whatever model(s) they choose, and view in Windy (as is now done by all other GRIB viewers).
For us offshore sailors, who commonly have the ability to download a GRIB over low bandwidth interfaces which wont reliably support an online session, this would be a great upgrade vs existing GRIB viewers (many of which are a bit clunky).
