Whether sauna is hot or not depends on whether you enjoy the cold water plunge afterwards :)

The typical preset on dry saunas in Bay Area is ~165 F (73 C). Which is cold. Loss of time and money :). Usually, by closing or throwing cold water on sensor, one can make it to 180-190 F (82-87 C) - this is where you start to feel like you are in sauna, though it takes prolong time to heat you up enough to enjoy the cold plunge. If you're lucky enough, you can get to 200, 210, 220 F (104 C) - this is where you start to feel relaxed with heat working inside you.

>Are you actually throwing water? Because even with 80 the steam is pretty hot

Of course those numbers would be impossible to enjoy in steam sauna.
