Hi Guys
Since modern Internet browsers introduced new technology "Service Worker", we have developed offline mode of Windy, thanks to it.
Offline mode was just released, and it is in testing mode.
It is available only for desktop browsers so far and can be reach just on this link: https://www.windy.com/offline
You are welcome to give it a decent try and let us know your feedback.
Known bug: stuck download
There is one BUG in offline mode, we are aware of. Downloading of offline data, gets sometimes stuck. Reloading the page, and opening https://www.windy.com/offline helps, but this can not be permanent solution. If you are a techie, maybe you will be able to help us, find this nasty BUG.
Problems accessing Windy.com
Service Worker acts as a proxy server in between your browser and Internet, so if you will have a feeling, that there is something wrong with access to Windy.com, just delete Service Worker, and you are fine.
How to delete Service Worker
In you browser, go to View -> Developer -> Developer Tools
In Developer Tools go to folder Application, then select Service Workers, and here Unregister
Of course all this you must do on www.windy.com address

Thanks for sharing this update. I tried the new offline mode and it’s great to see Windy taking advantage of service workers for smoother access without a connection. I’ll keep testing it and share any feedback, but so far it’s a really promising addition
its more smart to pay subscription who supports this
im right?
