Yes. Actually 100C. The sauna i usually go to goes up to 240F (115C). The reason this doesn’t immediately scald you is that air has a tiny fraction of the specific heat of water, so the energy being transferred to the skin is at a much lower level. You can reject a large portion of this heat by sweating

There used to be a Finnish sauna endurance competition where the temperature was 110℃. It was canceled in 2010 after one contestant died.

This is a big sauna, most of the air is not at that temperature. And I would certainly not attempt endurance in it, but the thermometer on the wall usually is between 235F and 245F
