Live weather completely off during real storms. Is Active Sky worth it in 2024 for accurate real-world weather matching?

Hi everyone,

I wanted to share an experience I had yesterday during an online event on IVAO, flying IFR into Paris on MSFS 2024 with live weather enabled.

In real life, Paris was getting absolutely hammered — massive thunderstorms, airports closed, tons of go-arounds and rejected takeoffs visible on Flightradar24. I’ll attach a screenshot of what Flightradar showed at the time.

In the sim? Completely clear. CAVOK. Nothing. Not a single cloud matching reality. It was honestly pretty disappointing, especially during an online event where immersion matters.

So my question is: is there a better alternative for realistic live weather in 2026?

I’ve been looking into Active Sky, but I’m not fully convinced yet. I watched a video by EasyJetSim Pilot titled "Is Active Sky Really Better Than MSFS Weather? | Full Review & Live Weather Comparison for MSFS 2020" : and interestingly, in several parts of the comparison, the default MSFS weather actually looked better than Active Sky, which confused me a lot. That video was for MSFS 2020 though, so I’m not sure how things stand now on MSFS 2024.

I also came across REX Atmos, but the reviews seem really mixed. From what I read, you can tweak colors and visuals, but the settings don’t automatically adjust as time of day or weather conditions change . you have to do it all manually. Apparently the day-to-night transition is particularly lacking. So that put me off.

Has anyone tested Active Sky recently on MSFS 2024 and can confirm whether it genuinely improves live weather accuracy , not just visuals, but actual storm placement, wind, real-world matching? Is it worth the investment in 2026?

I also just came across a brand new tool called StrataWx, released in June 2026, which apparently injects live weather directly into the sim in real time as an alternative to Active Sky . has anyone tried it yet and is it worth it?

Thanks in advance!

I’ve been in StrataWX since its release and I’m satisfied, but the product is still in developement. I’m in the beta and it’s improving day by day. They take care of the product a lot and they support you in things that improve your experience even not directly related with their weather injection. Very active team in Discord.

In my experience all is better than Active Sky, that I left months ago. But remember it’s still in constant development. You may get two or more updates a day. The updating system works very well

Hi @louisdmrt and welcome to the forum !,
Your post has been moved to User Support Hub that is more appropriate for community support.

Thanks for the feedback ! It’s reassuring to hear the team is that responsive. So does it works well with the real weather ? I mean does it represent the real weather better than the default msfs and AS ? Like location of storms cell, turbulence..

Do you have some screenshots of the game while using the addon ? It’s interesting, I just discovered this new way for weather injection.

The representation is fine but there are limits imposed by infraestructure: transitions are improving but still are a bit abrupt, but I feel that nothing can be done on this matter. On the other hand, depicting clouds, for instance, is correct for me. Turbulence winds have been improving day by day and now I feel them very realistic.

This is a screenshot of this very morning above Eastern Africa:

I use Active Sky and can’t fly without it. I initially bought it because coming from XP12 I noticed right away there was absolutely no cloud turbulence in 2024, and the flight model felt repetitive and mechanical. AS fixes that a great deal and adds a lot of life to the flight model and weather behavior. Plus it slightly improves the clouds visually. It definitely adds more variety to the clouds.

7

It looks amazing. I have never seen that with the default weather injector in the game. Good to know about the transitions. The cloud depiction and turbulence improvements is what matter most for me on msfs I think . Is it stable enough ? Do you get some crashes of freezes?

8

I have heard good things about Active Sky. I’ll have to watch some videos on it to see if it is worth the cost.

9

This is StrataWX, not Active Sky, correct?

10

Yes, StrataWx. It’s very stable and I’ve suffered no CTDs with it and I have not seen anybody complaining of that.

11

To elaborate a little on the limits @VillaJota mentioned: weather addons use the weather preset system, which can’t place weather in the distance. e.g. you can’t avoid storm clouds visually like you can with live weather, and your plane’s own weather radar won’t be able to show you any different weather ahead, because all weather will be the same everywhere in all directions at any given moment. (You can still use NEXRAD-type weather data displays to avoid distant weather that the weather addon doesn’t consider you to be inside yet, though only if they’re using a data source other than the sim weather itself.)

On the other hand, I’ve seen posts saying that the live weather system never creates any weather at all above 20k feet (is that true?), while the weather preset system can obviously go higher than that, which would make weather addons clearly superior for high-altitude flying.

12

Exactly this is the worst issue that you can see in StrataWX. I suppose that other systems have this problem too. Clouds appear or disappear before your eyes when you move from one “weather tile” to another, and though the system used by StrataWx is very gradual there’s still a transition, something that Live Weather does not have because you move inside a global weather system.

I don’t think that this can be easliy solved without MS/Asobo’s collaboration, so we all must wait and maybe enjoy the rest of the features.

13

Yes me too, especially on xp12 and msfs but as i said theres a lot of videos and as you can see, the one i mentioned at the beginning seems to show that AS is not as much accurate. There are too many mixed reviews, so I’d like feedback from people who actually own it.

I was an ATCO and qualified met observer for many years, and I use Active Sky and find it creates a very realistic looking scenario. However you have to bear in mind that any system that uses METARS is very rarely going to exactly match the weather conditions for an airport or area. The reason is relatively simple, METARs are compiled either by an automatic system or following human observation at specific times, normally every hour or half hour. If the weather conditions are changeable, as they often are, then five minutes after the observation is made the conditions can be quite different. In reality ATC should advise pilots of deteriorations in weather conditions if they observe them, or Runway Visual Range equipment or the Met Office advise them. ATC are normally unable to advise of improvements unless these are made officially by the Met Office.

So I think it is more important for any simulator weather system to prove a realistic looking weather system, visibility precipitation and cloud formations , than try to accurately copy an out dated METAR. I find the Active Sky system provides more realistic looking clouds, despite the limitations of MSFS in being unable to show proper cirrus or thunderstorms, which is a great pity.

In reality METARs are historical records, and only a guide to what to expect, which makes flying much more interesting and demanding. Hope that helps.

Thanks a lot for your feedback. It’s really interesting !

Now would be the time to pull the trigger, It’s on sale.

17

Amazing, thank you for letting me know!

I tried AS for 12h in different scenarios.

Then uninstalled it.

The Passive mode did not work as described for me. It did not change turbulence in-sim at all. No difference beween AS turbulence min or max.

In active mode there were a few scenarios where the clouds looked better than default WX.

Otherwise it is very limited. Several places there were BKN/OVC layers at 5000ft+ irl. AS did not depict these at all, showing Cavok all the way - bcs Metars said Cavok, which means no clouds below 5000ft. Default WX had these clouds and layers.

Also believe Asobo is working on the WX server side atm. Seen changes, with clouds up to 35000ft, different cirrus clouds etc.

Meteoblue is doing something good, imho. Also compared to ‘that other sim’, where cloud-layers, altitudes, always 30NM vis etc are wrong many times. In-sim WX has been pretty correct for me. Hopefully they keep working on improving cloudscapes, CBs, turbulence etc.

19

That’s exactly what we almost had Pre-SU7 in November 2021 (2020) until they rushed in the METARs to appease the Vatsim crowd who harvested votes, years on there’s still issues with METARS and “Bubbles” (as seen in the Bug Forum) causing problematic Live Weather but Asobo, as per the last Q&A, don’t seem bothered by the problems at all. So we’re stuck with this until they wake up and realise a lot of this system is still broken.

I am very happy with Active Sky so far. It’s the first time where I am experiencing proper turbulence during a flight and it makes it so much more interesting.

Also, the clouds look much better in many weather scenarios. Just doing my first airliner flight with this add-on.
