You’re simply wrong about your own experience there.

At 90% humidity and 100 F the heat index is 176 F which is astronomical.

A heat index at 125 F is lethal to any human being eventually…at 176 F you’re dead in 15 minutes.

Either the temperature was lower, the humidity was lower.

Lots of people take the temperature high point they see and the humidity high point they see on the weather forecast and assume they happen at the same time. That’s generally not the case.

So people say “it was 100 degrees and 90% humidity”, when actually it was only 50% humidity at the hottest part of the day and something like 80 degrees when humidity was 90% in the evening.

Everyone’s guilty of this. They’ve experienced a really hot and humid day, they then tell the story with the 2 highest numbers because it felt really hot.

It’s an accidental embellishment and ultimately leads some people to die of heat stroke as “they’ve worked through worse” in their own mind when the warnings come in with numbers they think they’ve experienced before but haven’t in reality.
