I've played every day (no time travel) and I've only had one. It was very early in the game so I thought it was something that happened all the time and didn't even take full advantage. I have seen random shooting stars since then though.
just once, only knew bc my villagers were talking about it. Isabelle didn't announce it, though really she never seems to announce anything lol, honestly don't really see what the point of her job this time around is when every day it's just "nothings happening" lol
Multiple times per week, it seems. I have multiple stacks of fragments because of this. Cycle might've broken now that I've had rain 2 days in a row though (went without rain for a good week or so prior to this).
I had a cluster of five or six within the span of a few seconds once, but then there was nothing for over an hour after that until I logged off. Haven't had any other shooting stars/meteor showers, though. Neither Isabelle nor my villagers have ever said anything about a meteor shower.
I've had several days with shooting stars (usually gaps of anywhere between 20-45 minutes between and five or so stars at a time), but no meteor showers.
I've been pretty lucky in Meteor showers so far. I've had two 'announced' ones (The first large meteor shower was before Resident Services) but a ton of smaller meteor showers, like around 3 times a week. The smaller meteor showers might or might not have Celeste and spawn meteors in batches of around 5 every 30 minutes or so.
i've never had a meteor shower and i've been playing since the 19th/no TT! celeste has visited once, and i've had some stray shooting stars, but never a big shower. i've visited another island with one though, and it was really beautiful!
Had the game since launch and no showers yet. Having said that I don't tend to play much later than 10pm so I may just be missing them (never had any villager dialogue to suggest they're coming though).
