I have read somewhere that you can know the air temperature by looking at the way your cat sleeps:

If your cat is all spread up, it's 25 C (77 F) and more.

If he wrap himself up a little it's about 20 C (68 F).

If the cat is wrapping himself up strongly with head covered with his tail it means 15 C (59 F) or less.
