It’s pretty insane. Need to be prepared for any kind of weather. We had a 121F swing this year in Minneapolis. It was -21F on January 23, 2026, and 100F on July 27, 2026.

Those could very well be some of the best places to be at if it wasn't for the heat on the hottest days (10°C colder would be much better, obviously). It's also important to keep in mind it's not the same to have a single day at +40°C than a whole month at +40°C. It's a common part of the narrative spread by negationists that we already had sudden temperature spikes recorded decades ago, conveniently ignoring the worsening sustained temperatures that have been recorded for years. Anyone with a pinch of curiosity can check the numbers.

Maybe, but I’m of the opinion that the best places to be will be those with shade and working aquifers as those become fewer and fewer

How old is this map? It was -40F in Southern Michigan in 2015 or 2016 and it's definitely been 104F in the same place in recent years.

To be fair, some of the marked locations are near the great lakes, so if having a large water source is one of the metrics those ones at least still fit.

That is absolutely ridiculous.

Huh, Palliser's triangle.

Except the lakes are polluted already and going to get far worse, as is the land.

Bald Eagles on lake michigan only average I think like 7 or 10 years, the ones inland like 15 or 20 or something, if I recall the numbers exactly but it's a big difference and it's because of the pollution.

The largest recorded temperature change in one place over a 24-hour period occurred on January 15, 1972 in Loma, Montana, when the temperature rose from −54 to 49 °F (−47.8 to 9.4 °C).

Just a wild place

Can confirm. Was in Belgrade MT one day in April where it went from -19F to 43F over the day, and it wasn't abnormal at all.

Note to self: Don’t live there.

Don't worry it's a dry cold

America and Canada need to get that rash looked at.

That's not even uncommon. We get that pretty much every year. People think it's cold all year around. Nope. Not at all

Thanks to global warming warming, that rash is spreading and it won’t be long until most live there.

cries in Minnesotan

I'm so glad I live in NS.

And a humid heat

Not on the West side of the map it isn't

Just gotta watch out for the humming but sized mosquitoes out there right?

It's noteworthy because the frequency and extremity are becoming more frequent and more extreme.

Oh yeah. For sure

Most of the marked locations have significant and worsening wildfire risk

The terrifying part is that adjacent to the Great Lakes was projected to be ground zero for incoming climate change refugees. Now it’s looking like they’ll be dried up

We've had -40C but maybe not +40, though we are certainly creeping closer.

Minnesotans don’t cry, we’re tougher than that, or at least have realized that if we do they either freeze or turn to steam.

Those poor bastards probably think its normal.

Wouldn't west coastal be better? Water to help regulate temperature, and you don't get the hurricane effects of the eastern coast

Yeah, I know my home has seen both those temps in my lifetime, but is not on the map.

Maybe it's only in the same year?

Beautiful demonstration of continentality

wait it isnt?

Huh?

Iowa?

Rising sea levels, tsunamis and earthquakes. Oh my!!!

Plus, you need desalination to be able to do something with ocean water

Wait...

-40c == -40f

Really?

9/5(conversion ratio) of -40 is -72 which is 32(offset) below -40.

So... (9/5[F/C])*(-40[C])+32=-40[F] is where they meet.

The place I grew up in is one of the places marked on this map. At one point in time in the 90s we had one of the highest swings of temperature in a single day that had ever been recorded in a single place where we had nearly a 40 degree temperature difference between nighttime and daytime. It's also one of the highest diurnal temperature places. During the winter time, it often gets well below zero. And I believe the record set in the 30s was negative 43f degrees. In the hottest temperature in the summer has been well over 100, nearly 110. And for an area in the high desert, that is normal.

I grew up in the center of the red blob. Highest temp I remember is 112F and lowest is -52F. Those aren't even records. Wind is brutal as well.

Is that true on a global level?

I took the family on a road trip through South Dakota this summer. For some reason in my mind, I thought South Dakota is north - and north is cold. Jesus fucking Christ was I wrong. It was unbearably hot. We tried going outside in the Badlands and had to get back in the car after like 5 minutes. Fuck that place and it's crazy heat.

Where I live in Sweden I have not seen quite that spread of temperatures yet. But not far off... I have seen -43C and +35C in the same area.

I live in Canada in one of those places. Once the area I live in was on the news because it was colder than Mars that day lol.

Are you talking C or F? Im pretty sure a 40 F degree temp swing happens every year in Minnesota, probably multiple times. The record in the us is 104 F in a single day, in Montana.

I'm in Calgary and I remember chatting with some folks in Denver a few winters back. We were talking weather and they said "oh its super cold here right now, just hit -10 f (-23 c)" and I was like "yeah cold here too, just hit -65 with wind chill." They asked me if I meant celcius or Fahrenheit and I just said "honestly at this point it doesn't matter."

There is a place in Saskatchewan that had +50c and -50C in one year. Wild that people live there, +50C is way too hot for me.

My first apartment in Calgary had an issue with the fire alarm going off in very cold nights since it was an old style that used (in part not the whole system) a piece of metal though the wall and went off when the difference between the inside and out side was to much (IE on fire inside). The issue was that when you keep the inside at +20C and the outside is -45C the alarm goes off and everyone has to go stand outside and wait for the all clear.

That being said I will take a dry Alberta winter over a damp one any day. -40 is fine with me (not if I stand outside too long and die though). Really once you are at -20 its not much different, just die/get frost bite faster.

Now break it down into 5 year blocks showing sets of stations added in each block.

this summer has been unlike others. you might have done the exact same thing in half the country.

when i was a kid (seems like eons ago) we vacationed there a lot, in north and south dakota (and a little mt and wy). mom and me loved the badlands. the terrain and features, wildlife, the night sky... i don't remember it ever being "too hot" to be outside. we camped, in a tent or popup; so outside is where we were basically all the time.
