35 degrees and it's just the beginning. I can't understand how anyone can be outside by their own will like this (unless you're forced to work in those conditions, construction workers and similar).
Come to the southern US where humidity is at an average 75% all year round. Not only is it hot, the air is hot, and heavy, and wet and will make you feel stickier than a woman in a bukkake
On average, the UK (assuming this where you're referring to) gets about 50-60% humidity during the summer. UK gets more humidity during the winter than summer. So no. It's not, haha. Granted, I do believe you when you say it sucks. It sucks here too. I hate those times I walk outside and it's so hot, it feels like all of the air in my lungs gets sucked out
