I haven't experienced ACNH snow. I started ACNH in May 2020, and southern hemisphere winter is June - August, but I only remember a lot of rain and fog! I am actually completely OK with that, because a lot of the southern hemisphere doesn't get snowfall, and my island happens to be on that hemisphere. There may have been snow at some point, I'm not sure, because I did take a short break at some point while I was playing Pokémon.
However, winter is starting again, and the other day I awoke to light snow fall on my island, followed by the sun coming out. It was lovely!
I don't know if there will be any real snow this season, but I'll be happy either way! I'm actually enjoying
not knowing because I like experiencing the day to day weather changes! And also, I love the bright green of the trees, grass, shrubs, etc.
