Island weather seed tool [Datamining]

I'm currently in the middle of tracking my weather to find my island seed. How many days did it take you guys roughly for it to determine yours? I just track enough for it to determine my daily weather pattern and haven't had a meteor shower since I started tracking.

I agree with @tajikey . Use your past screenshots to track either "unsure rain/snow" or "unsure no rain/snow". If you press (A) button on a screenshot, you can see the date and time it was taken. Rain will always last the entire hour, so you can't go wrong with this method. It's important to understand though that if the screenshot was taken on a day where you added another player to the island, the weather may be incorrect since all rain and snow stop for the rest of the day, so skip those days.

Man, if this is true, that means all those people who haven't had a meteor shower yet (Including me) might never get one and because it's just in the code that way. That SUCKS majorly haha.

Yep, it would seem it's pseudorandom rather than being truly random.
 
Tracking rain is better than the sunny and the cloudy days. The best data is when you have stars/Celeste with star times. Just make sure your star times is accurate. I gotten lucky and have been getting stars and rainy days. Unfortunately my seed means I get too much rain for June.
 
so all this time, it isn't random? sad! i kinda like having the surprise more but would be neat to know the meteor showers though.

also, today is LITERALLY the first time isabelle has announced a meteor shower. what a coincidence that i found this thread lol. but i can't enter enough info sadly.
 
uuuuugh finally found my seed and i am sad i have so few heavy showers. i guess knowing is better than growing more and more cranky as they don't show up lol.

i found my seed just entering in meteor shower info (a dozen stars & 3 gaps). super easy on my end. i tried using data for regular weather but it didn't work too well for me (not the tool's problem, i wasn't working with more than a dozen pics and didn't feel like TTing to gather a bunch of data). i'm sure it would work great with more data tho. stars was just faster for me!
 
Question: Would using the TV to hear the weather forcast tell you the correct weather to enter?
 
i finally found my seed! i spent a couple of hours trying to figure this out and was getting frustrated haha, this is what worked for me in the end:

* i timetraveled back to the only date i knew i had a heavy shower, i set the time to be 7pm - i also opened up a stopwatch app and set it to go at the same time i set the time to 7pm.. when i was in the game, i started counting the minutes i saw stars appearing, i counted about 8 of the stars and entered the info as i was counting

* i then went through my screenshots and found days when i had rain, some of these days i had taken screenshots at multiple times when it was still raining so i was able to enter that information as well - i couldn't tell if it was heavy or normal rain most of the time so i always chose "unsure rain/snow", i entered about 7 days of this information

* after i did that i searched for the seeds and had 4 possible seeds - i opened the yearly info for the first seed, found the day i was currently viewing the heavy shower at and used the stopwatch to see if the minutes and seconds matched up, and they did, perfectly! to double triple check, i timetraveled to another scheduled heavy shower in march and it was there!

i'm so glad i finally found my seed 😄 it's a great one too! a rainbow on my birthday, some auroras in december i'm super excited about

I just found mine! 193431387. I was trying to figure it out the past few days but it led me to a dead end so I was tracking the weather wrong (I have had rain the past 3 or 4 days so I'm pretty sure I was just reading the different clouds wrong).

I went back to my last known heavy meteor shower and I also used a stopwatch. I managed to get a perfect match after tracking two minutes worth of stars down to the second they showed up. Once I had the seed, I went ahead to a day the seed said had a double rainbow and it matches so I'm assuming I did it all right. The seed even found that I had a meteor shower on the 18th of May and this was information I excluded since I wasn't 100% sure it was a heavy one or not.

While I probably won't check this information every day since I like the mystery, it's nice to have as a reference!

Pretty excited about all of this! I guess we're 🌈 island (a few years of at least one 9 rainbow month) which makes me smile. I already loved my island a lot prior to this and I'm just so happy right now!

link in case I ever lose it lol

Editing to add the star seconds too I tracked too in case anyone wants to see what I did. The tracker does mention that the algorithm will allow measurements to be up to 2 seconds late so don't worry if you can't get the exact number if there's multiple stars in a row since it gets really confusing sometimes.

I recommend turning up the volume on your switch and keeping your eyes on your timer and computer and just marking when you hear the sound of the shooting stars. Click the box to the right of the minutes and it'll allow you to input the seconds of up to 8 stars per minute and heavy showers will either have 5 or 8 stars a minute so you'll know you counted wrong if you end up with something else.

What's the best way to find your seed? I've put 2 meteor shower dates and 4 days of weather, but it still says I don't have enough weather information. Is it best to go day by day recording like the same hour or is it better to record multiple hours of weather each day?

Look through screenshots you've taken and locate the timestamp. If it's a picture with rain, then find the date on the calendar, select the beginning of the hour (if the snapshot was captured at 7:46a, then put 7:00, since if it was raining at 7:46, it was also raining at 7:00), then put "Unsure (rain/snow)." If it's a picture without rain, then do the same thing, except put "Unsure (no rain/snow)." Do this for as many pictures as you can, even if it's the same day, but a different hour.

I struggled to locate my seed until I stopped tracking clear/sunny/cloudy etc., and added the two Unsure options above.
 
I found mine!! It was frustrating to figure out but I finally got there c:
My meteor showers are not plentiful unfortunately, but they're not completely cursed!
There's none June, July, August, or December, but there are 2 in September and October, and 1 in November :)
Plus some light ones sprinkled in between, including tomorrow! Of course 2019 had 2 showers most months, with only one month having none :,)

I'm very excited about this, thank you for sharing! I do like the mystery of discovering things yourself, but because meteor showers bring rare resources, I am okay with cheating a little by peaking at when I can get them.

Don't take the fine showers for granted. They start later, and bring fewer stars in sporadic bursts, but add up quickly. I wished on the first two bursts last night at 9:01 and 9:41, and collected 10 fragments this morning. Without knowing my seed, I would have found zero.

I put tomorrow's mini shower in my calendar after I got my seed so I won't forget!
 
I finally found my weather seed!!!! 😁🎉🥳💫🥰 I think I put in some information in wrong or something, twice, so I just time travelled back two months to the days I knew I had a thunderstorm and a rainbow, then time travelled to the days I knew I had aurora borealis and snow, and recorded the information for those days. This is my weather seed

I'm a bit sad that nothing special is happening on my birthday, but overall I am pleased with the 2020 forecast
 
I got my seed! It really helped that I had a few meteors last night, I was able to record the time stamps which narrowed it down a lot.

Now that I know my seed, I'm curious of the average heavy shower per month/year, rainy day average, etc. It doesn't seem like there is any data on that and I understand why (I'm sure there LOTS of seeds) but I can't help but wonder how "good" my seed is.
 
I finally found my correct seed! The weather and the meteor shower dates are correct, but I think the times of shooting stars are off so I might try to redo that. But with two known meteor shower times, I know it is the right one.
 
I spent ages putting weather in from screenshots and I must have made a mistake because it didn't work! I wish there was a quicker way to do it!
 
i finally found my seed! going through your screenshots and putting unsure (no rain/snow) or unsure (rain/snow) plus just knowing the date of one heavy meteor shower did the trick for me!
unfortunately my seed sort of sucks for heavy meteor showers.. i have 2 in august then NONE till december 😩
but knowing when the light meteor showers are happening (and i do have a lot of those) will definitely help. i probably won't use the site much other than knowing meteor shower/rainbow dates.

In my experience, it's probably better to put less data into it than filling it up with weather stuff since it sometimes can be subjective (sunny vs cloudy). Meteor shower dates, light showers, or visits from Celeste help best imo. But, I would still take note on a separate notepad of dates and times of the weather.

For example, I have a meteor shower on 5/31 and then a known light shower + Celeste visit on 6/17 and 6/30. But I noted elsewhere of my weather:

6/12 sunny/cloudy (@1pm)
6/13 sunny (@8am)
6/14 rain (@2pm)
6/19 rain (@8/9pm)
6/24 cloudy (@7pm) & clear (@11pm)
6/29 rain

So when I got a number of potential seeds, I checked each one with the weather data I got. I knew it wasn't right when it said I have a light shower on the 6/29 when I know I have rain instead. When I found mine that was most likely it, I TTed to a known meteor shower and having a heavy shower then confirmed it for me!
 
This worked for me too.
