2 minutes later at 17:05z they shift back to being incorrect.
HOW is this not on the devs radar?
I suggest every person experiencing this to just keep submitting zendesk reports.
Iāve had the same problem for several flights in a row. Please fix it!

Same problem here, happening more and more frequently and really killing my immersion.

Yup, the ASOBOSOFT fly swatter is fully active again. Almost whacked out of the air with extreme wind direction changes and pressure changes on my current flight today. Plane had to climb steeply to regain 2000 ft of altitude. This seemed better for a while, but itās back with a vengeance again. Long overdue for a fix!
EDIT: And againā¦this time plane dove at 3000 ft/min to acquire altitudeā¦overspeed. This is so lame. They have to get rid of that ā ā ā ā METAR!

Still getting this in cruise every 10 minutes or so, I really really hope there is a fix on the horizon. Even when I can recover, my altitude alerter blaring at me for 30 seconds is terrible
EDIT: Latest experience was flying LFPO-LPPT at FL350.

Today the wind shifted direction and increased from 35kts to 117kts instantly. I donāt have to tell you what it did to my planeā¦Pretty sure my copilot was spitting out her pearly whites from faceplanting on the upper pedestal. I wonder if we can send an insurance claim to Asobo. Iām done crying about this. Itās time to just be amused, I guess.

Yeah this issue has been going on for so long now, I donāt know why it isnāt bug logged or feedback logged.
The way they tag and categorise bugs in this forum is so inconsistent.

This happens every single day at 2300 UTC. Just make sure you are flying at a cruise altitude (FL350 for instance, making sure you arenāt hitting ground level METARās) and into a strong headwind, somewhere around 2255z - 2300z the winds will change suddenly. Around 2300z - 2305z they will go back to normal. Every day, 7 days a week, like clockwork. Simple to reproduce yet still a bug after a yearā¦

Is it only that time or is it every hour? Could be because they changed to more frequent data from Meteoblue in su7? If not i think itās a data error that time of day everybday.

Youāve articulated the MSFS experience perfectly.

Hmm, Iām wondering if this could be due to new wind data becoming available but not being injected into MSFS correctly. I noticed when I was using MSFS a lot I would experience the same wind shift at around 17:00z every day. I noticed it happened at other times but often didnāt take note of the time.
For the airline I work for in flight planning, we get new upper wind data available 4 times a day, known as a wind data reference. The times this updates is roughly around 05:00z, 11:00z, 17:00z and 23:00z which would make sense for what youāre observing and what Iāve observed.
Iād bet this is what weāre seeing but for some reason when it injects then new wind data itās like itās temporarily switching to older data. Iāve often observed it switch to wind speed and direction which can be around 24-48 hours old.

It could be the upper wind data updating like you said. I have noticed this happen at other times, but I donāt remember the exact times. I donāt believe itās every hour @Perrry - I know I typically do a flight every day that I start about 2200z and the wind change always happens at 2300z. I even slow my airspeed down way before then every time because I know itās going to happen and kick me into overspeed if Iām going too fast.
You donāt really notice it as much if you have a tailwind. I will try to do some more testing around those times you said, not sure if Iāll be able to hit the 0500z.

Just had the wind change happen twice in the last 20 minutes or soā¦ what time is it right now? 2318z.

Iāve experienced two over Portugal, roughly 10 minutes apart at 0400Z and 0410Z
And again today, this time back to back, about 10 minutes apart in the climb. Almost lost control both times. Blew an altitude restriction and got reprimanded by ATC. Seems to be getting worse by the day. What a downer.

I think they inject a gradient of wind data from ground to high up from Meteoblue. That gradient will change every hour. Maybe that could be the issue? Before su7 we had data from meteoblue that was updated 2 times per day. We could turn back weather by changing system time pre su7. After su7 we get more frequent updates and that we canāt change anymore using system time. Asobo confirmed that they use more frequent updates in a q&a right before release of su7.
I think pre su7 weather moved in time depending on our system time. After su7 they set a static weather until next update comes from Meteoblue. More accurate maybe but much more hard transitions in weather and the weather feels less dynamic. I liked pre su7 more with less updates and more of a fluid/realistic behaving weather system.
I think those hard transitions we have will be hard to fix. Itās raw data they get from METAR and Meteoblue. They need to manually smooth out those if Meteoblue not will do that in the future for Asobo. And itās not easy to make 60 layers of atmospheric data smooth every single hour everywhere globally. I hope iām wrong and they nail it soon 
I would like the weather as good or better than it were pre su7, then iām happy again.
Or a toggle to activate that 2 updates per day Meteoblue live-weather again. I donāt need it to be more accurate than that.
I donāt think it would be that hard for them to add some sort of āsmoothingā system like ActiveSky (and even FSUIPC) had. If the wind drastically changes around my aircraft, fine, but introduce code that gradually changes a couple knots/degrees per second rather than all at once.
Another major overspeed for me above north Holland, 0435Z.
But wind can change drastically. Maybe not exactly every hour. But i think servers know when that change happening and could have the smoothing process only when that change is active.
But if i think about how little improvements weather has get since release actually i have not seen a single improvement. When i reported 225@3kts bug everywhere over the whole world to zendesk, instead they added METAR winds in the update right after the release because many here at the forum told that was needed instantly when 225@3kts was a server issue.
Then in su4 they suddenly removed gusts.
Then suddenly in su7 they completely changed weather system to be much worse with those METAR and more frequent updates that also changes visuals everywhere.
Now it feels like they going to focus make METAR and Meteblue match and those hard transitions for 8 years to make it feel as it did at release instead of adding new things that improve weather.
I just gave up and shut down FS because the extreme wind shifts (3 - 4) of them within the first 40 minutes of flight) completely ruined the experience. This combined with the fact that my GPU and CPU will run at 100% in map view and marketplace when itās absolutely useless, but stuttery at cruise altitude with my GPU practically sleeping at 40% and CPU at 20 - 30%. Terrible hardware allocation of resources and a ā ā ā ā ā ā and unreliable weather system implementation. Becoming really disillusioned with this program. Oh, and forgot to mention that I lost ATC as well during my flight.

Same bug here. Around 23 zulu time its much worse. Sometimes changes are pretty extreme. A week ago I was going for my final approach on Nice airport and suddenly 4 knots headwind to 145 knots side wind 1500 feet from the ground. My TBM crashed of course
