VERY generally speaking, 20s are warm, 30s are hot. Humidity changes this a lot. And yes, personal sensitivity to heat plays a role. I live in a dry climate, and I feel rather comfortable until we’re close to 30 ºC. I remember reading something like the ideal room temperature for humans was around 20-22 ºC.
For those using F, this is, more or less, the scale of C:
Below 0: freezing (0 ºC being the freezing point of water, duh!)
0 to 10: cold (don’t go out without a coat)
10s: cool (a sweatshirt or light coat may do)
20s: warm
30s: hot
40s: uncomfortably hot (stay in the shade and hydrate)
50s: you’re dead (or you wish you were. Unsafe for humans)
Eh, as a weirdo who uses Celsius a lot but lives in Buffalo, NY…
-20s is cold. Coat, gloves, scarf, & hat. Long underwear. Not too much evaporation from the lake since it can freeze, so not much snow.
-10s is chilly. Coat, probably zip it up towards the lower end of the range. Decent chance of apocalyptic snow.
0-10s is cool. Wear a sweater.
10s is nice. Maybe consider long sleeves & pants if it gets a bit cooler.
20s is shorts & t-shirt weather.
30s is all AC, all the time. Uncomfortably hot not too far into the range.
40s is “the humidity is now so high the air is soup, filled with mosquitoes”.
Hot is still relative. Are you talking about soup, a cup of coffee/tea or outside temperature? People would probably answer differently in each instance.
Well… I said VERY generally speaking. And as I’m defining a gradient of temperatures (clearly it’s not the same 30 °C than 38 °C), I’m also defining a gradient of “hot” sensations, from feeling a bit of heat in your body, to feeling like an oven. That’s the thing with generalizations. I’m not trying to be precise here, just give a general idea to those that are not used to Celsius (I’ve seen the same being done with Farenheit and found it useful). Cheers.
