The way you have thermal strength indicated is orange-red-dark red. It's very hard to see if the thermals are ok, good or excellent.
Here is a Windy example. The thermals seem like they should be good over a large area (lots of red)
Compare that to a Skysight example at the same time and place. It's easy to see that the thermals might be good over only about 1% of the area.
The Skysignt color scale is much much more informative.
