Thought this was interesting to see.
Australia:
The Adelaide Hills, which includes Mount Lofty, saw nearly an inch of snow, or 18 millimeters, in an occurrence which occurs once every few years.
This is similar to parts of northern Mexico seeing snow climatological.
Uruguay:
Snow in Montevideo, Uruguay, is something that occurs roughly every five years,
which makes it similar to the odds in Charleston, S.C. Normal highs in Montevideo are 14C (58F) and lows are 6C (43F, but being so close to the water makes it very difficult for any snow to mix in as the winds will blow off the water in any colder situations.
