The meaning of the symbols you highlighted:
Partly cloudy (or mostly sunny)
Mostly cloudy (at night)
Partly cloudy (at night)
P.S. during the night time, the sun symbol is replaced by the moon symbol.
The Route planner is not available in the app, Android or iOS.
As said here : ‘It is almost impossible to make route planner available at mobile phones due to the complexity of the UI and its control.’
@Korina , Hello and thanks for your reply.
With "traffic conditions" I mean traffic jam, men at work, work under process... or any situations along the path planed to go from Departure to Destination. Especially when using Windy maps for car rides...
Sorry I should have realized there is no mountain in Washington DC :-)
In addition to the explanation from @Yves70, sounding is available with right click on mouse on desktop and a long press on mobile app screen.
@malai852 Hello, are you referring to a difference between Windy AQ stations or AQ layers? Air quality stations on Windy report real-time values, however air quality layers such as PM2.5 show forecast based on data from Copernicus (CAMS).
