The way you experience temperature heavily depends on the relative humidity.

E.g. I find 0C in London way colder than -15C in Northern Europe.

That is actually a common myth: https://www.theglobeandmail.com/life/health-and-fitness/fitn...

I also think that you wear different clothes and are more prepeared when it is -15.

Nah, he has no idea what he's speaking about.

It's not _just_ humidity. Rain just simply can't exist at -15C, so you can't get your clothes moist because it can only snow, and that snow is cold enough not to stick to you at all.

I am not even going to start on the fact that you can walk miles of snow and not get wet, while walking through miles of slush... Well, I hope you understand the distinction.

Subjective temp is relative to habituated climate though. Where I live (subtropics) people complain that it's 'cold' if temps drop below 20C.

I imagine 32C might feel damned pretty hot to an Alaskan.

I've been there a few times in the summer. Some people were complaining about 75F weather, saying it was hot. 75F is the temp that I still wear a light summer jacket, and 70F is pretty chilly to me.

Either way 90F without AC is too hot, even for me.

30-32C & humid is common in the summer months here. It truly wouldn't occur to me to use AC (even if I had it) in those modest conditions!
