Official Real Weather Report Topic

Just leaving a few sites for both weather forecast and history to compare with ingame weather.

What would be really useful when you change the date/time is to have a reference to the sunrise/sunset for that date/location as well. It would make fine tuning an event when you want to transition from night to day or vice versa so much easier. At the moment it's a crapshoot trying to pick the right time.

I did notice a nice thing that the sunrise/sunset is changing correctly with the date, which you can test by keeping the same time 16:00 and just changing the month at Spielberg (say from 28/09/2021 to 28/12/2021). Showing that sunset/sunrise time on the UI when you are changing the time would be really helpful. I liked the light mist that appeared just above the track in Dec.

>>With the option to customize event date, users can now also customize the season the event will be run under.

Where is the Season option? I could only see changing the date, but the season was changing with the date. Or is that what is meant by having the option to change season with date? It would be handy to show the season for a selected dat well, given the tracks are global.

I think it would also be useful to show the Track temp and ambient track temps as well for the selected date/track combo.

So to summarise, helpful weather info to show on the event configuration screen, so you can reference when changing the date/time:
. Sunrise/Sunset time
. Season
. Ambient/track temps

ps: sorry, I may have posted this in the wrong thread.

 

Silverstone 2008 springs to mind, July 6. I did a test session at 14:00 track time and while in-game the track was damp and the car was recommended wet tyres, it wasn't actively raining and the track was ready for slicks after a few laps. This was with the Formula Reiza.

Race highlights

I've also attempted Spa 1998 but as per the changelog, Spa hasn't had historical data applied to it yet

 

Out of curiosity, is the historical weather based on local time or GMT?

 

Suppose this scenario:

25 minute race at a predefined date (say, may 1st 2021).

Race starts at 8:00 AM, time progression set to 60x (so, a 24h full cicle will happen, and each minute will be 1 hour).

What's gonna happen to the dynamic weather?

1 - there will be just one weather slot (since the race has only 25min and the slots are hourly based)

2 - there will be 25 weather slots, one per minute, due to the time progression setting, spanning though may 1st at 8:00 am to may 2nd at 9:00 am

Regards!

 

If I understand this correctly is would be the 2nd scenario.

 

setting custom dates to january trees still have leaves, shouldn't they be without them in winter? am I doing something wrong?

 

I guess it depends on the trees! I noticed Spa had a bit of both, leaves and no leaves. Ever green will never fall off.

It also depends on the track. North or south hemisphere?

And finally, I think the current build works on a few tracks only. We better check the patch notes!

 

sorry, i forgot to mention: Nordschleife, not evergreen trees as far i can see

 

Yep, the trees are green at the end of Dec. No snow either like Spa. It seems seasons are still to be added to Nords?

 

Yep, these are all WIP and won't be finished for a while.

 

Edit: User error!

 

Tried a race at Spa with real weather and custom date June 4 2021, yesterday there was a flood there, eau rouge turned in a river at 6:00 pm. This is what I had in AMS2 at 6:02 pm:

 

Yesterday I was getting heavy fog all day in Nords, while it was raining heavily, using real weather in test day

 

Did you try earlier times to see what happened? The rain is often over by the time the flood occurs--it's from an upstream river overflowing or runoff from surrounding territory, not just the rain falling at the moment. Pics and videos of the flood waters flowing that I saw showed it had already stopped raining and was even partly clear in some. The weather in the game is at an hourly resolution...so it may never match reality so perfectly, but there should have been some significant rain at some points in the 24 hours or so before the flood

 

Session time/weather setup tip:

As there's no sunrise/sunset time indication in AMS2 I looked around for a solution to my "I want to do a session that runs over the sunrise/sunset transition, so I can experience dramatic lighting and weather changes and really enjoy the fantastic graphics while hooning around".

Sunrise and sunset times works great. Just plug in the closest city/region where your track is, the date (day/week/year) and bingo.

Another useful site is Weather History & Data Archive | Weather Underground which will also show you the temperature if you want to try and pull up some snow on real weather.
I did notice some discrepancies with real weather though. eg:
Heavy snow disrupts Nurburgring 24 Hours prep date of heavy snowfall was early morning 26/03/2021 but trying that date in game (on Nurburgring not the GP track) just gave fog with only a tiny dusting of snow on the environment. I was expecting a snow dumped environment with clean tracks (still looked great though!).

Even in mid-winter I haven't seen a real snowscape yet.
