I work tourism (guide) and summer is horrible.
You can't hide from the heat, if it's cold you can just put on more clothes.
Now it's 12 degrees C outside and I'm working in a hoodie, jeans and boots. I'm perfectly comfortable.
Almost all of this years summer has been 20+ degrees here, not even in white, thin clothes is it comfortable.. Just sweaty and miserable.
Especially when you are hiking and doing physical activities...
Autumn is really nice in exchange, a little rain doesn't matter.
