So, I don't island hop a ton like most people, but when I do it's in bulk like most. I've just had 7 islands in a row with rain when it is not raining on my own island. Is there any significane to this? It feels really weird because I can't think of ever having had it rain on them before... at all.
I've had all of my mystery islands be raining on two separate days when it was sunny on my main island. Seems to be a feature. I used it to catch a coelacanth.
I don't know if there's any significant reason but I've encountered rainy islands when mine is not or no rain when mine is. Yesterday I got an island that was dark grey and rainy and I felt cold watching my player ran around in a summer dress.
