The American Midwest is more humid than Southeast Asia.
I have actually speculated that this is the case for a number of years now. I recall my days trekking around Vietnam, Malaysia, Thailand, and Singapore, hot and sweaty, but not unbearably so. Years later I moved to the Midwest, and always struggled through the summers. There would be days I would go lay out--perfectly still--and still sweat like a glass of ice tea.
That's the evidence. In the Midwest, you can break a severe sweat doing nothing. But in Southeast Asia, it takes some intense working to get that sweaty. I was walking around outside in Jakarta Sunday afternoon and didn't break a sweat. I sit outside for my meals here and don't break a sweat. It's hot, and not that comfortable, but not that humid, either.
To be fair, not every day in the Midwest is like that, and this past summer was amazingly mild. Really enjoyable, actually. But it still seems that, in general, the Midwest is more humid than Southeast Asia.
