Trust me, 16 degree C is freezing for us as we have 30+ degree all year long. The hottest between Mar and May is 40+. It's burning. I remember back to early 2000s, we once had a small winter which the temperature was wondering between 15 to 20 degree C. It lasted for about one month. Many caught flu and cold jackets went very good sales that season.
I spent quite a bit of time in Taiwan, Honk Kong, India, etc. where such conditions as you mention are common.
It was stifling for me...but at least I was raised in a part of Texas where 40 C is not an uncommon thing during the summers and they have high humidity. In that part of Texas they always had a decent Fall, Winter, and Spring, though all of those together were about 5 months of the year where 7 months were quite warm.
Now, here in Idaho, it is the reverse. We have about 5 months of Spring, Summer, and Fall combined, and the rest is more winter-like.
Maybe it is because of my upbringing, but I have decided I like this better. LOL!
