110C is not that unusual in the Nordics (although way above average, it's for tougher sauna goers). I've been in one. Not most people's cup of tea though, the experience is comparable to the opposite of a long cold plunge.

110 is only on the top shelf, middle or lower is much cooler. For a dry sauna you really want to be well into the 100s to get a proper kick out of it.

A dry sauna sounds terminally boring. The point of Finnish saunas is that they are dry and hot, but you can adjust the pain...experience, I mean, by throwing water on the rocks at intervals of your choice.

Whisking can make up for the boringness of a dry sauna (hitting yourself with some birch branches).

Well, not the branches as such but their leaves.

I haven’t used a >95C but every sauna I’ve been to in Europe has options for 80 or above. They sometimes have cold ones at 70 or whatever too

No point in going to saunas in America or uk as they require wearing clothes.
