+20 to +25 is the perfect temperature Below is cold, above is hot
At 0, snow and ice form, so +10 is in the middle between your regular room temperature and freezing (i.e. jacket weather)
+30 is the kind of weather when you better be naked or wearing lightest of clothes or you’re gonna get baked over time. Not deadly by any means, but highly uncomfortable.
I take it in tens.
-20° to -10° is full parka weather. Your breath freezes on your clothes and moisture in the air dries up.
-10° to 0° is winter coat and scarf weather. Damp cold. Snow and ice but you don’t feel like your eyeballs are freezing.
0° to 10° Jacket weather. Early spring temps. Pretty mild in either direction.
10° - 20° Hoodie and t-shirt to taste. Basically the comfortable human range for most.
20°- 30° T-shirt time. Anything above 25 is solidly in swimming weather territory.
30°- 40° Time to seek some shade. Heatstroke and heat exhaustion are variable in this range the low end is a health risk for seniors the high end is a risk for even the hardcore heat lovers in their prime.
