This is the article it came from if you want to read more of the methodology.
DV and Mojave’s relatively lower scores are probably due to low humidity, and possibly the presence of wind. Humidity and lack of wind were among the requirements for his “oppressive index”.
UPDATE – I just ran into a paywall for that article, one I’ve never hit before. Whether something changed or I just looked one too many times, dunno.
I thought that, and its interesting, but like… when you’re actually out there, I can assure you of the oppressiveness of it 
I recall moving to Arizona in the '70s, in August, thinking that the slight wind and +100F temp felt like when you open the oven to take out the cake…
Spent 3 years in Arizona, between the Air Force assignment and going to school at ASU, never had a car with air conditioning. Just roll down the windows… Heh, at pilot training, the T-37 had air conditioning, but it didn’t work below 20,000 feet. No kidding, the operator’s manual said that. Geesh…
100F and a slight breeze is downright pleasant for us these days. Our week of ~115F temps broke thanks to a dust storm, but the exchange we made for the heat is overcast brown skies and breathing in dirt for a few days… There are always debates and pissing contests about who has it worst but heat is just bad no matter where you are. Here in Phoenix for the average person, anything under 110 is generally “tolerable”.
I do some volunteer work outdoors with the unsheltered population, in particular on Friday afternoons. The two worst days this summer were pretty big extremes for our summers. One was 117F and dry, the other was mid-90s and humid. Both of those days really took a toll on my body, at least in the short term. I’ve also seen more people suffering from heat exhaustion in the last few weeks than I usually do, but luckily part of this volunteer work is with a group of med students so we are prepared to take care of folks.
Hottest I’ve ever been in was 128F. I walked outside for two seconds, said “NOPE” and went back inside.
I have had my log fire burning all night long to keep my cat happy. The joys of August in Tasmania, Australia.
Thanks for your detailed answer 
Yeah, same here. I really like being outside, but in Portugal from June to October it’s really hard from 11:00 onwards. While it may not be very hot, usually 30-35C, it is dry, windless, and the sun is scorching with UV7-10, so it feels hotter than it should. The difference between shade and open fields is immense.
I think the tourists are often misled, they come here in peak heat. When you walk around Lisbon, Algarve, etc, all you see is tourists looking like lobsters.
I have barely gone outside this year and already have wristwatch tanlines. Would probably pass as a mexican in the US 
Some weather stations here were crossing the 40 degree mark, like Bratislava - Koliba station that has hit 40.8°C (105 freedom units) a few days ago. But yeah, it’s only around 12-15% humidity… It’s definitely a weather I’m not used to – in my hometown seeing temperatures above 34-ish was quite uncommon.
Also, I’m glad I’ve got at least a portable AC unit. While terribly inefficient and loud af, it can cool the room by around 1 or 1.5 degrees while it’s running. Not a lot, but it definitely feels better, plus the moving air probably makes it feel even a bit cooler.
Speaking of measurement… Does anyone know of some nice indoor temperature and humidity sensor? I was thinking about getting something, but I have NO idea what to look for (features, price, accuracy, …)
depends on what you want to do with it. Logging? Or just reading? Do you want a display or is working with an app fine? I just got myself Govee Wi-Fi Wi-Fi Thermo-Hygrometer | Govee EU which does what I want. Much cheaper elsewhere.
Ok mine is actually the bluetooth variant which is much cheaper. Can’t seem to find it on their webpage though…
this seems to have a display and bluetooth functionality
I’d like to have a display and also the possibility of downloading logs periodically.
The H5075 seems to be able to do that based on what I’ve read on their site – a CSV file with all the logs is perfect for me, as I can generate the graphs myself. Thanks for the suggestion!
I use Apollo Air 1 but it’s a bit expensive.
A 2-pack of the Govee H5075 is already on its way to me 
And also, that’s a full-on air quality sensor unit – way more than I’d need. Still cool tho!
This has been a bother to me as I get older. Its not that hot, but being in direct sun light is hard.
I’ve noticed that, too – the sensation of the sun “beating down” feels stronger than when I was younger. Also since cataract surgery and lens replacement my eyes have become a little more sensitive to bright sunlight.
I also just got a set of prism-lens glasses to correct slight occasional double vision from my left eye misaligning but that’s a whole 'nuther story. The prism correction was far, far too strong and as a result triggered a cascade of other issues and side effects. After talking to my optometrist hopefully we’re on the same page now and the replacement lenses will be just what I need – and no more. We’ll see…
August in South Carolina is known as Hell’s front porch.
Also, I’m curious…
How much is the temperature reading skewed when I let the AC blow directly onto the sensor of a thermometer? (It’s a different thermometer – it’s got a cable with a metal thingy at the end).
Would I have to protect the sensor from direct ariflow with some sort of enclosure to get something accurate?
Yes. A better solution would be to move the sensor (on the cable) to a more suitable location.
Perhaps they’re planning on exporting hot air balloons …
Why is that, really?
If the air flow has the same temperature as the otherwise still air, shouldn’t the sensor just register the same temperature? I mean, the sensor isn’t sweating so to get a cooling effect from moving air, (and the thermometer seems from its display not to have a function calculating an “effective temperature” factoring in both temperature and wind).
