I was just thinking back to the climate of Bodie, California and that unbelievable range with practically freezing nights and hot days in July (it's got a smaller range in winter).

It's something like over 20-something C range or over 40 F, in an average day, and I wonder if there are other climates like it anywhere.

I also wonder what's the phenomenon behind allowing such a huge day-night gap to happen. I'm guessing it might have to do with thinner, dry air in highlands? So perhaps it's in these places to look for the biggest diurnal ranges.

Anywhere on the Yellowstone Plateau has very high diurnal ranges in summertime, by world standard. Yellowstone doesn't have as high of a range as Bodie does, though, especially in winter. A lot of high-altitude climates in the western United States exhibit these characteristics.

If one wants to look for high-range climates look for high-altitude places that exhibit dry air, deep inside continental interiors, at about the 45th parallel (to have maximum sun angle variation, both seasonal and daily). That's my best guess.

Dry upland and inland cities tend to have some really extreme diurnal variations, but I'm not sure why.

Puno, Peru has a 24 degree diurnal range in July ( -6 to 18C ), and it's only 15 degrees south of the equator.

Yakutsk, Russia has got to have one of the widest diurnal ranges in the world. Average high is 77°F/25°C in July and -33°F/-36°C in January. Record high is 101°F/38°C and record low is -84°F/-64°C. 269,486 people call this city home

It's hard to believe that at some point, Yakutsk will be too warm for me.

Yakutsk does not have high diurnal range - what you're talking about is high annual range. Diurnal range refers to the difference between the average daily high and the average daily low.

Oops (ESL guy here) Well, if that's the case, I suspect a mid latitude desert location would have the widest range. Tibetan or Mongolian Plateaus?

Ah, yes, I forgot about the Andes. Many of the Altiplano climates exhibit high diurnal ranges in wintertime. This also occurs on the Tibetan Plateau, although winters there are usually colder.

I know Alamosa, CO because it's in a valley and surrounded by sand which heats up and cools down faster. While the average is not quite 40F, it's very close and just recently it in the last week of this month it was averaging some days with 53F diurnal differences.

Here's the climate:

Here's last month's stats, look at the final two weeks!:
