When people first started joining the Fediverse in large numbers, a lot of them asked "Where are the weather accounts?"
If you're one of those people, please check out the FediMeteo project at:
It has weather forecast accounts for cities and towns across almost all of Europe and North America, plus Australia, New Zealand and Japan.
To follow an account, click on a town or city, then copy-paste its address into the search box in Mastodon etc.
