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."

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.

No break it down into 5 year blocks showing sets of stations added in each block.

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.

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.

[-] adarza@lemmy.ca 3 points 2 hours ago

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.

[-] Grandwolf319@sh.itjust.works 4 points 6 hours ago

Is that true on a global level?

[-] Rawrosaurus@lemmy.dbzer0.com 4 points 5 hours ago

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.

[-] vala@lemmy.dbzer0.com 11 points 8 hours ago

Wait...

-40c == -40f

Really?

[-] untorquer@quokk.au 16 points 8 hours ago

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.

Beautiful demonstration of continentality

[-] UltraGiGaGigantic@lemmy.ml 10 points 11 hours ago* (last edited 11 hours ago)

Those poor bastards probably think its normal.

[-] CptOblivius@lemmy.world 7 points 7 hours ago

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.

[-] titanicx@lemmy.zip 3 points 8 hours ago

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.

[-] MonkRome@lemmy.world 5 points 4 hours ago* (last edited 4 hours ago)

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.

[-] protogen420@lemmy.blahaj.zone 2 points 10 hours ago

wait it isnt?

[-] hydrashok@sh.itjust.works 63 points 16 hours ago

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.

[-] errer@lemmy.world 50 points 15 hours ago

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

[-] Crackhappy@lemmy.world 14 points 15 hours ago

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.

[-] dumples@piefed.social 12 points 14 hours ago

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

[-] iamthetot@piefed.ca 10 points 13 hours ago

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

[-] dumples@piefed.social 3 points 13 hours ago

Oh yeah. For sure

America and Canada need to get that rash looked at.

[-] aeronmelon@lemmy.world 28 points 14 hours ago

Note to self: Don’t live there.

[-] tempest@lemmy.ca 34 points 14 hours ago

Don't worry it's a dry cold

[-] chuckleslord@lemmy.world 12 points 14 hours ago
[-] 0ops@piefed.zip 4 points 13 hours ago

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

[-] W3dd1e@lemmy.zip 14 points 14 hours ago

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

[-] spacegoat@lemmy.world 5 points 12 hours ago* (last edited 12 hours ago)

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

[-] Atropos@lemmy.world 2 points 11 hours ago

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

[-] Vandals_handle@lemmy.world 1 points 30 minutes ago

Oceans in Southern California not warm enough to sustain hurricanes yet, on path to. Warming ocean will also raise humidity and have less of a cooling effect.

[-] xnavy@lemmy.zip 3 points 10 hours ago

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

[-] SkaveRat@discuss.tchncs.de 2 points 9 hours ago

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

[-] Zachariah@lemmy.world 32 points 15 hours ago
[-] CrabAndBroom@lemmy.ml 7 points 4 hours ago

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.

[-] D06M4@lemmy.zip 33 points 16 hours ago* (last edited 4 hours ago)

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.

[-] BooBees@fedinsfw.app 19 points 16 hours ago

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

[-] CarbonIceDragon@pawb.social 8 points 15 hours ago

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.

[-] bedwyr@piefed.ca 6 points 15 hours ago* (last edited 15 hours ago)

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.

Gonna be a desert soon, all the over farming

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.

[-] excursion22@piefed.ca 1 points 46 minutes ago

You haven't had real winter until you've had eyelash icicles.

[-] Blackfeathr@lemmy.world 8 points 16 hours ago

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.

[-] LastYearsIrritant@sopuli.xyz 3 points 11 hours ago

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?

[-] Malica@lemmy.zip 1 points 10 hours ago
[-] Echolynx@lemmy.zip 2 points 12 hours ago

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

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.
