Meteonook is a website created by dataminer Ninji (check him out on Twitter @_Ninji) that allows you to find your island's weather seed. The seed was created when your island was created and can't be changed.

By inputting more and more data into the tool, it will narrow down the possible seeds for you. Once you find your seed, you can look at what your weather will be for the 21st century basically! It even will tell you when you get meteor showers and when exactly (down to the second) shooting stars will fall. Once you get your seed, make sure to write it down somewhere!

Have fun!

My seed (2083329091) is pretty OP btw for heavy meteor showers in 2020 and 2021.

and here's some cursed seeds:
74411 and 237827 have 0 heavy meteor showers in all of 2020...

Some tips I found to work well in finding your island's seed quickly:

-Collect weather data on the top of the hour (X:00) as it will be most obvious which weather you have during that hour (i.e. clear, sunny, etc)
-Multiple heavy meteor shower dates (these are when Isabelle announces it or villagers talk about it)
-Light meteor shower star times to the minute (this is when you have shooting stars/Celeste but no Isabelle/villagers mention)
-Keep in mind it is possible for Isabelle to not announce a heavy meteor shower if she has other news to announce (like a villager birthday)
-Dates and times when you have rainbows (single or double, but there is a difference), aurora borealis/australis, or heavy fog
-TTing will allow you to collect data faster, however, it is possible to do this without TT if you have specific heavy meteor shower dates and/or specific light meteor shower star times (to the minute). So next time you see Celeste, try and record the minutes that you get shooting stars.

Definitely gonna take a look at this. Thanks for sharing!
 
Let me know if you have any questions, and I'll try and answer them. I helped test (and break a couple times lol) the tool, so I can point you in the right direction if you need it
 
I think I like the surprise more!

Yeah being surprised is fun too. This is just in case you're curious or looking for a specific type of weather (like a heavy shower during a certain zodiac period)

I'm not getting a seed even though I'm putting in the correct weather at the correct times on the correct date.

I'd suggest checking the data again, it has to be exact... Is it saying you don't have enough info? Because that means you need more data
 
Thank you so much for sharing this! I'd love to find out what my seed is bc so far I've havent had a single meteor shower, and I want to know if I should just stop waiting for them this year
 
Got my seed after a bunch of searching through screenshots and my log of Celeste visits lol. It's predicting shooting stars tonight at 10:39 so I'll see if it's right or if I messed something up somewhere.
 
This personally feels like a bit too much. If you know the weather down to the second, it ruins a lot of surprise. And there's no guarantee Nintendo won't later patch something in to change up how the seeds work.

I feel the opposite. If I know which days there will be a lightning storm, I will be sure to play during that time
 
This is super helpful, thanks for sharing! Unfortunately, I deleted all my accidental screenshots so I basically have nothing to go off of :cry: gotta start from square one I guess

EDIT: I went through my old texts to find when I told friends about Celeste, which really helped narrow my seed down!

My weather seed is 2052276881.

I was able to get it in a few minutes of filling out the weather data because I had saved the dates I had heavy meteor showers and Celeste for the span of about 5 months.

I can confirm (painfully) I had no heavy meteor showers in August.
 
As someone who's hunting for zodiac fragments, this is an absolute godsend! Ninji and everyone that worked on this has all of my thanks. Now I don't have to shell out absurd payments for Zodiac frags!

My seed is 1773952012. Its pretty good if you ask me! Lots of meteor showers! Im curious to see what is considered a good seed!
 
I put in data from 10 different dates, and it said it wasn't enough. How many data points are needed before it will run the numbers? I'm really curious about my meteor shower schedule.

I think it might be easiest if you already know your meteor shower schedule like @SaltedKaramel and me knew. Just keep adding more dates!

I should have a picture from a meteor shower day, so I'll get that put in next time I'm on. I had a rainbow day, too, so hopefully that helps.
 
I'm gonna try to find mine :)

I know I had a meteor shower 5/31 so I'll try to use that to my advantage.
