Beautiful demonstration of continentality
kinda explain why some plants from the south can also survive up there, like 1 species of cactus.
Those could very well be the best places to be at. 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
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.
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.
Most of the marked locations have significant and worsening wildfire risk
There is a place in Saskatchewan that had +50c and -50C in one year. Wild that people live there, +50C is way to hot for me.
Too hot even
Nice catch
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.
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.
That’s not even uncommon. We get that pretty much every year. People think it’s cold all year around. Nope. Not at all
It’s noteworthy because the frequency and extremity are becoming more frequent and more extreme.
Oh yeah. For sure
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.
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?
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.
It’s more of a dry cold though!
Average year in south eastern Ontario :)
Those poor bastards probably think its normal.
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.
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.
Yeah, I think the record where I’m from was somewhere in the neighborhood of 65 to 70 degrees in one day. And I spent two years in Minnesota and there weren’t a lot of days where we had that were 40 degrees swing where it went from near freezing to 80s or 90s during the day while I was there at least.
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.
wait it isnt?
We’ve had -40C but maybe not +40, though we are certainly creeping closer.
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.
I prefer the converted fractions for ease. Your solution while right will confuse most Americans. (1.8x-40c)+32=-40f
Dear fellow Americans: Fun tip, lazy (but inaccurate) math is (2x-40c)+30= -50f which when you get to normal ranges works well enough in a margin of error. Or just learn to enjoy the beautiful thing that is Celsius and stop using/converting to Fahrenheit.
is -40 not a normal temperature, at least compared with +30c?
Americans use fractions daily. The rest of the avoids them. The dimensional analysis maybe.
I’ve done 9/5+32 in my head so much it’s easier and faster for me. Then it’s 100% accurate to boot.
America and Canada need to get that rash looked at.
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.
No break it down into 5 year blocks showing sets of stations added in each block.
