A mid-high 20s Celsius can be a hot summer if that is what you're acclimatised to. Humidity plays its part too.

20 Celsius is warm Summer. Not hot

20 Celsius is warm Summer. Not hot

You missed the point. A classification scale doesn't necessarily reflect the reality of living in any particular environment and the peoples acclimatization to that environment.
28 degrees Celsius and 97% humidity is hell even for someone acclimated to 35 degree dry heat.

[Aspar]

Hot, dry summer with temperatures up to 46 degrees celsius.

[Bobby Martnen]

In between hot and warm

[Papastratosels26]

Hot dry summer average 35'C

[Bobby Martnen]

The ideal weather would be about 60-65 degrees year round.

We're in the far end spectrum on "hot summer" Cfa. It's hot but not that hot. For example we're in the middle of summer and the weather is around 24 but in January it might reach 38.

[Zroota]

A little cooler than the surface of the sun :)

[Senpai]

Extremely humid Summer

[Rhovanion]

Subarctic climate (Dfc) with cold summers and cold winters. The temperature usually hovers around 15-16°C (~60°F) in the summer. Definitely my kind of climate!

We usually have snow throughout April (and sometimes into May), we usually don't start seeing tree foliage until the end of May. Early June still feels very spring-ish, and by mid August, you already start seeing hints of autumn colors. The best thing about living this far north in the summer is definitely the amount of daylight we get. The sun sets around 11:00 PM and rises again around 2:00 AM, but it's never dark during those three hours, only a very bright twilight. If you go a bit further north, you'll get proper midnight sun in the summer (which I have experienced).
