I went to Las Vegas in August for my honeymoon, and everyone kept telling me about the wonders of dry heat.
I ended up with heat exhaustion after a day or so, (and here was no hiking or biking or anything like that.) I was miserable and it didn’t seem much different than 100° in humid Chicago.
90 hands down.
It’s why I moved south. I hate being cold with such a passion, and I like being hot.
The thing that pisses me off though is that when it’s 90 outside, every building I go into wants to take it upon themselves to make their internal temperature be 50 degrees and I’m FREEZING.
66 degrees or so would be great. I once decided that my dream location would be Buenos Aires, Argentina, because the climate sounds so wonderful, averaging in the 60s-70s much of the year. (Also tango, classical painters, and lots of steak…)
It seems odd that temperatures in the 90s feel so abysmal to me, even unclothed, even though basal body temperature is almost 100. But bathing in water that warm is pleasant. (I think it’s partially something to do with heat transfer in gas vs. liquids vs. solids, it just feels strange that I prefer to be a little cold.)
This sums it up for me. If I had to choose only one forever, it would be 66, but 90 during the day in the summertime is perfect summer weather.
I’d pick 66 over 90 any day. In fact, 66 is a little warmer than optimal for me, especially if I’m being active.
The difference is that with humidity, it feels like your crotch is constantly hosting new forms of life, and it feels like you need a shower immediately after taking a shower.
Except that according to Pai325, that was apparently what it was like in Las Vegas as well: “It didn’t seem much different from 100 in humid Chicago.”
As the OP, I appreciate wanting a range of temps for a range of activities. However, I have no interest in it EVER being 90 degrees, in part perhaps because I don’t like lying on the beach in the sun (I burn, also it’s boring) and in part because I am quite comfortable in shorts and T-shirt at 66 degrees.
I think what intrigued me about the radio hosts is that they weren’t saying, Gee, I wish it was 90 here so I could lie and sun myself next to the pool (though I suppose they may have been implying that); they were saying that a 90-degree day, in general, was preferable to a 66-degree day. Which I just find…odd. YMM and evidently does V (though I’m intrigued that the votes for 66 here seem to outweigh the votes for 90).
66F for me, anything over 80 I feel like crap. If the 90 folks are lizardmen I must be a polar bear or something.
90F. Though, to be honest, I’d prefer it to be about 10 degrees F cooler. I think 80F is fantastic, even when humid out. Though if I had to choose between 90 and 66, I’ll go for the 90 (now if you said 70 and 90, maybe that’s a more difficult question).
I would take 56 or even 46 before 90 if I ran the Illuminati weather control machine.
Now that I think about it,I am honestly more comfortable in shorts at 36(no wind and less than 2 hours) than I am in any choice of clothes at 90.
It’s all that fur…
80 is the beginning of “uncomfortable.” 90 is “too goddamn hot.”
I live in Vegas. We can go months with less than 10 days total of highs lower than 100. I fucking hate it.
Present-day global warming will affect Urth’s climate to such an extent that 90F is cold in the far future.
Low 70s feels about right. Before I had central air in my house, I would have said mid-60s, anything to escape a hot summer. Now that my inside temperature is good, I can stand a little warmer outside. It also depends on what I’m doing outside. If I’m working up a sweat, I’d rather it were cooler.
Simpler answer: any time I can wear shorts.
66 is probably more comfortable than 90 to me, in most situations… but not all. Sometimes laying out in the sun in 90 degrees or swimming is very nice.
Now that I live in Houston, 90 degrees always comes with a heaping helping of humidity, and is never any fun to be out in though. 90 in Oregon (where I’m from) was actually pretty nice some days.
I can’t vote for one or the other though.
Us lizardmen are not amused. 
We just want to be treated like everyone else. For now.
Just came back to post that it has now reached 90 F for the first time this year and it is. Brutally. Hot.
oh well
Prefer about 24C but if I had to choose between the given alternatives, I’d go with 19. 32 is too hot for me, especially if humidity is high.
90 degrees [32 C] is too cool for me to really enjoy. 36 C or thereabouts is preferable.
I had a job intetrview once for a position in very hot location. HR woman (a Brit) was warning me that I won’t like the heat. “I assure you it won’t be a problem, I enjoy the heat”. She just looked at me sadly and shook her head like I didn’t know what I liked. Grrrr.
66 is too cold for sitting around doing nothing.
90 is too hot for anything except sitting around and doing nothing.
My optimum temperature is about 75, with a light breeze. Ideal for just about anything.
