For people of the world, that's about 121°C. BTW, I've been in a sauna in Sweden where the thermometer displayed 100°C. The women sauna, according to my mother, was only 96°C.

Out of interest, was that the ambient temperature or was the thermometer placed above the source of steam?

They normally keep the thermometer on the opposite wall to the source of heat.
