This table reflects my experiences.
| Temp. (F/C) | me | Germans |
|---|---|---|
| 90+/31+ | hot | omg you can't go outside, I can't sleep, I definitely can't live in a place like this, this is dreadful |
| 80-90/27-31 | normal summer | hot |
| 70-80/20-26 | slightly cool - nice | nice, but sometimes too warm |
| 60-70/15-20 | cool | pleasant |
| 40-60/5-15 | cold | cool - pleasant |
| 32-40/0-5 | freezing | cold, but not enough to take seriously |
| <32/<0 | still freezing (my scale stops) | actually cold, but not enough to keep you indoors |
