Hottest, 102 F. Coldest, somewhere about -20 F or so. Central Indiana.
Coldest, I’m not entirely certain, but I think it’s around zero - I was waiting for a bus in Milwaukee, and vaguely recall seeing one of those time/temperature signs saying that it was somewhere around zero.
The hottest I’ve been in was around 120, walking between (non-Strip) casinos in Las Vegas in mid-August.
112(F) in Phoenix. Humans have no reason living there, what a hell hole. And that was a relatively un-extreme day.
-25(F) In Wyoming. Everything below about 20(F) feels the same to me, too damn cold.
Las Vegas was definitely amongst the hottest places I’ve been as well although I didn’t vote for it since I didn’t get a formal verdict on the temp. It was pretty hot just to walk from the parking lot to the hotel: there’s a reason hotel rooms can be $30 or less during summer weekdays.
The next morning, I felt like going to another casino and stepped out onto the strip, and it was already too hot for me to feel like even crossing the street at 8 am.
Erie PA, experienced a high of 100 and a low of 18 below zero.
125F while driving through Death Valley (Baker, CA). I see the record is 124F, so I may be misremembering or the highway billboard was not calibrated correctly. My AC (which the sign also advised turning off, as if!) was not running as cold as usual, but there was no problem.
But I was in the car. Helping my nephew move into an upstairs apt in Tucson in 105F heat was rough, but it did not last that long.
The Arabian Sea, with seawater injection temperature at 95F? That really crippled the ship’s AC, and the result was 125F and very humid at AMRLL (lower level, Engineering spaces, leaky steam equipment). For DAYS.
Coldest were winters in Chicago and Idaho Falls. Bearable with proper clothing, nothing special.
Edited typo.
-2 in NY; 110 in Vegas
My last bike was liquid-cooled; and on days like you describe, stopped at a stop light, is when the fan would decide to go on and blow hot air onto my shins.
Being a native Californian my additions to the thread are not noteworthy. Highest is probably around 110 on multiple occasions (but it’s a dry heat). Lowest (California)…I remember a cold snap in 1972-ish, when the temps got into the low 20’s and the fountains on the Berkeley campus froze. Outside of that: a business trip to Minneapolis in January, temps in single digits. Boring, I know.
And I got that confirmed today.
Last July, we had a +40C day.
Today, we had a -40 C day, with windchill to -51 C.
Walked to work because the car wouldn’t start.
