95 is high for Finnish saunas in Finland at least. Public saunas are very rarely so hot here, and few like it that hot.
Edit: to put it into some numbers, per one study[1] Finnish sauna sessions were on average at 75.9°C with SD 9.9°C. If we assume normal distribution, that means that more than 97 % of sauna sessions are at < 95°C.
I actually like them that hot. I look for 90+ saunas, and once was in one that claimed to be over 100. Although I have no idea how accurate that is. They're very bearable to me. But if they're not bearable, of course you should look for a sauna that's not quite as hot. Or at least stay low; the higher you sit, the hotter it is.
You can have over 100°C. The amount of steam is a crucial factor. Even over 100°C doesn't feel that hot if it's dry, but at higher temperatures the "löyly profile" often becomes quite harsh.
In my case 95°C was without any steam; it caused me burning skin sensation and I almost collapsed after just 5 minutes, whereas pre-covid I could do 3-4 rounds of steam with towels pushing steam at me at the topmost place and last up to 20 minutes before I needed to leave.
