I found this map that visualizes the variability in day temp around the world and I found it interesting so I thought I'd share.



Most of it is what I expected, with inland North America being very variable as well as Siberia. I was surprised by the variability of Finland though, I guess it's very different than coastal Norway. Also surprised by the low variability of Antarctica, but I'm not sure how accurate the data is there.

what do they define as day to day to variability? There's 2 definitions:

1) average difference in daily mean temperature from one day to the next
2) standard deviation from the daily normal

(1) sounds like what "day to day variability" should mean but I've seen (2) used instead

Melbourne should be a bit whiter though.

It's number 1: a comparison of two days.

Also I found it here: https://www.reddit.com/r/MapPorn/com...re_around_the/

I admit not the most legitimate source lol. I'll pm the original poster and ask him where he got it from.

This is neat. The US part definitely agrees with what I've read, but I didn't know northern Siberia is that variable.

A summer/winter map would show an even bigger split in the winter. Most places have consistent summer temperatures, but cold climates can be all over the place.
