I live in CH too (for more than 20 years now) and although in can get hot in the summer, the humidity is normally much lower than the US east coast and southern states. I used to regularly travel to North Carolina from Basel (normally warmer than Zurich) and could really feel the difference, even though the temperatures were similar in the summer. In NC, A/C was essential; in Basel not so much.
