One way to solve your problem is to use a sounding, either the sounding included in the weather picker or one of the good plugins also proposed with Windy, SkewT and Better sounding. The last one has been developed specifically for paragliders : https://community.windy.com/topic/7960/sounding-plugin-for-paraglider-pilots

Those graphs should help you to check the thermals and their altitude max. Now, this sounding will not give you any indication about the vertical speed, you need to use other websites or application

@martymack Hi, you can set elevation in the app too, there is elevation bar in the side menu.

It seems to me that you can save your favorite page of Windy as a bookmark in your browser. It opens the page with the location, layer and diagram you want. Only possible on website.
In Airgram colors are used for temperatures at each levels which is useful too.
