This was done in Summer, not spring. I'd imagine summer nights wouldn't be as cold as Spring nights...

Desert wind is crazy in the spring. It’s a shame because spring is the most beautiful season there, by far. Just a bit hard to sleep in the gale.

Bike riding in the heat once caused me to come close to overheating. Stopping, finding shade, pouring water over my head and laying down finally brought my core temperature down in time.

I saw the same things begin to happen to my wife some years later when bike riding in the heat. I did the same for her and all was well.

Your reaction to heat is highly dependent on acclimation. I live in Texas and have to re-acclimate every year. Exercising on the first 85º+ day of the year is miserable, but a month later 85º feels quite tolerable, and 95º is doable, though performance suffers.

I grew up playing baseball and tennis in 95-100º weather with high humidity routinely. It wasn't pleasant, but nobody was getting heatstroke, nobody was cancelling games or practices. But on a visit to Montana a few summers ago, I saw that kids' baseball games had been cancelled because the temperatures had reach a dangerous level: 90º (in dry mountain air.) Same human beings, different levels of acclimation, very different safety thresholds.

I've never been in the temperatures described in this article, though, and I don't know what the physical limits of acclimation are.

What really matters is the wet bulb temp. For example, the Death Valley high today was 114°F (45°C) but at an RH of only 3%. That gives a wet bulb temp of ~ 65°F which isn't a problem with acclimation and adequate hydration.

Now if it had been 50% RH, the web bulb temp would be > 96°F which is not survivable by humans for very long because no amount of sweating in that humidity will cool you down.

A young couple and their baby and dog died of overheating on a day hike in California a few years ago.

> Now, I actively avoid anywhere much hotter than about 80F.

It is currently - well after sunset - 82°F outside. A couple days ago it was mid-90s in the afternoon, and it should get back to that after the current weather passes in another few days.

Mowing the yard when it's high 90s and muggy and sunny is not as rare an occurrence as I might like.
