Oh you dont know whats going on at the city centre. The charts are the average temps for Athens, (an average of every part of the city), so thats the numbers they upload on the net.
Besides, you really dont know about my heat sensitivity, dont you?
Ok. At Winter, I never wear a jacket, and I enjoy the low temps. No wait, I dont just enjoy being cold. I LOVE it! 
When I was 8 y.o. I stayed out for 2 hours wearing just a bathing suit, in a cold Winter day, at -8 Celcius, while snowing.
At Late Spring/Summer, its my living nightmare. I CANNOT stand the high temperatures. Its something I had ever since I was a child.
<<<<<<Loves Winter
<<<<<<Hates Summer.
I remember many times getting heat strokes, when everyone else was fine! Really, I do have a problem with high temperatures.
Banned for making me write all that.
