Did they match the current METAR? I’ve read an idea that the weather is delayed by 12 hours. When I flew last night the current weather was cloudy, but the weather 12 hours earlier was clear. The sim depiction was clear.

Well they don't use METAR in the sim so it's not going to match any local METAR 1:1.

It isn't always delayed by 12 hours. I've had accurate cloud cover, the Hurricane last week over Bermuda was in the right spot. (though it was pre-patch so no wind)

After the patch, wind is blowing in the right direction and speed, at least the wind according to Windy

I go to world map, and first select live weather, then I select my departure and arrival, etc.

Thanks for the work around. It worked in the last few destinations.

Every time I reload the sim it defaults to a theme weather. Your suggestion works each time.

sometimes people complain there are no waves

I did a flight a SFCO bay and and went on increasing wind surface from 5kts onwards. By 60kts the sea is moving, wavy, full of foam and white crests...beautiful!

So waves are working, the problem is the wind speed at which they are triggered. I believe in real life wind of 10-15 kts already makes the sea crispy.

So we need to find the file where to tweak that bringing the wind values down.

I suspect a similar thing happens to weather in general, both live and presets. All magnitudes are not well related

A wind of 10kts is the same as nothing, you have to increase wind energy a lot to feel it in the plane. Its a need of adjustment

In general, live weather is a timid representation of reality, it takes some parameters but not all

An example of my issue:

Currently where I live (Halifax, NS) is getting hit by the outer bands of the approaching Hurricane/Post Tropical Storm Teddy.  I figured I’d do a test before my power goes out.  This was around 20:30z

METAR showed winds 030/19, 700 ft overcast, altimeter 29.56.

The flight planning screen showed winds 033/9.

The introductory screen showed winds as 043/14.

My observations in sim (as best I could without a functioning ATIS) were winds roughly along the correct heading but only 4-5 knots.  So that’s four different sets of wind conditions, none of which match.

Altimeter was 29.88 which is nowhere close to current conditions.  It was indeed overcast but it has been that way all day so I would say that part is inconclusive.  Once I took off and got up to around 2000 feet or so, I started getting getting winds around 20 knots.

Both the winds and altimeter were quite a bit off from real world conditions.  I hope there is something that can be done as those differences are not inconsequential for IFR flight.  I’d love to see them find a way to incorporate  METARs into the weather modelling so we can get conditions in-sim that more accurately reflect actual live weather.

I’m going to submit this to zendesk as well to give them another data point.

They said they're looking into it in the Pre-release Q&A video.

Exactly my conclusion.

For me, if I select “live weather” as a preset, then fly, on the next launch of the sim, it loads live weather directly. If I select any other preset (other than live weather), it goes back to the preset menu on next launch. This is 100 percent repeatable in either direction on my system.

It should not be delayed, but sometimes it clearly is. The MeteoBlue NEMS global forecast model is run at 0000Z and 1200Z which are the two times that worldwide RAOBS weather balloon upper-air data is available. The model takes approx 5 hours to run, and is made available to end users (like Microsoft) at approximately 0530Z and 1730Z. The forecast model should contain forecast data for each discrete hour of the current day, and every three hours for days 2 to 7.

So, IF there is no delay in Microsoft ingesting the latest MeteoBlue forecast model into Azure and making it available to MSFS live weather clients, then if (for example) you are in Chicago, (KORD) and it is currently 21:15Z on September 22, then you should get the predicted weather for 2100 to 2200Z for Chicago on September 22. What actually seems to happen far too often is you either get the weather forecast the previous day at the same time, or from the same day, but 12 hours earlier.

I’m very sure the problem is in Microsoft’s end, not MeteoBlue’s. MB is a professional provider of forecast data to many industries, and their business credibility and reputation absolutely depends on delivering their weather products on time each day.
