I am writing to report that Navigraph’s weather data is consistently inaccurate. I never used the Weather layer before, but since the MSFS 2024 SU5 update introduced the Weather Radar, I started monitoring atmospheric conditions much more closely.
My testing across Europe proves that Navigraph often shows a perfectly clear sky while dedicated sites like Ventusky and local radars show active, severe thunderstorms (e.g., in the Salzburg/Upper Austria region). The Weather Radar in MSFS 2024 shows accurate weather that matches real-world conditions seen on various weather maps, yet Navigraph remains heavily delayed and misses major storm cells entirely.
We pay for professional tools, yet I am forced to use external sites to get reliable information. Please fix this synchronization.
So we can investigate, please provide specific time-stamped examples where Navigraph weather is inaccurate or differs from real-world weather. Screenshots help using Guide to posting Screenshots.
With all due respect, I am the customer here, not a beta tester or a data analyst. I have been flying in flight simulators for over 30 years. I know exactly how to read weather data and what real-time accuracy looks like. I ask for respect for both my experience and the money I pay for this service.
It is not my job to perform quality control for your company. The discrepancies are obvious. Instead of asking me to spend my time gathering screenshots and timestamps, perhaps you should prove to me—the paying user—that your data is accurate. Show me your evidence that Navigraph synchronized correctly with the real-world conditions in Europe over the last few days.
I am reporting a failure in a premium service. I expect you to investigate your sources rather than putting the burden of proof on the customer. I pay for a full “kilogram” of service, not half.
Hi Mariusz,
I´m not the responsible person in our team for this topic, but I have read in your initial posting and now in your answer that you mentioned the weather conditions here in Austria.
Luckily, I´m an Austrian, and I can tell you that we haven’t had any thunderstorms or rain in the last 10 days across the whole country, especially in your example areas (Salzburg to the south).
It was cold and partly windy for approximately 5-7 days, but always sunny, sometimes with a few clouds, but far away from rain, thunderstorms, or similar. Wonderful pre-summer weather here … no weather app, simple look out of the window
After a detailed analysis, everything actually lines up perfectly; description below…
Yeah, Navigraph shows the weather live and perfectly in sync with the other radars I used. The specific points of contact on my screenshots confirm this:
Front Location: The red, most active zone on the Navigraph map is in the exact same spot as the heavy rain core on Windy—west of Bologna, in the belt between Parma and Modena.
Situation at LIPE: Navigraph shows Bologna airport (the green LIPE icon) right on the edge of the yellow precipitation zone. This matches the data from the Windy weather station, which is currently reporting only “light rain” with 8000m visibility.
Movement Direction: The cloud and precipitation pattern on the flight map has the same “crescent” shape curved over Northern Italy as seen on the Windy weather radar.
Operational Reliability: Navigraph uses professional radar layers (often based on data from meteorological offices like Meteoblue or NOAA), making it just as reliable a source for a virtual pilot as dedicated weather services.
Bottom line: Navigraph passed the reliability test. What I see in the flight planner is exactly what is happening right now in the simulator and in the real sky over Emilia-Romagna.
Now it makes sense… Thank you to the entire Navigraph team for the quick response. I wish you all the best of luck in your further development and in your personal lives… THX PS. I didn’t include any screenshots of the G1000 Weather Radar—I forgot to take them from the cockpit, but today everything was perfectly in sync. Just to be sure everything is okay, after tweaking the settings in Navigraph Charts, I’m adding one more screenshot…
“Looking out the window” is not a professional way to verify global data synchronization for a paid service. I rely on meteorological radars and 30 years of experience, not anecdotal observations. Since you are so sure, perhaps you should prove your claims to me with screenshots and technical evidence from that time?
Exactly – why was it wrong yesterday but correct today? Mutual assistance should be the foundation of this forum! If Navigraph differs from professional radars, it’s a technical flaw that needs a fix, not a weather report from your backyard.
But the true way … When the sun is shining, and an app tells you that it is rainy, the “professional way” is obsolete, and the app is wrong. With or without any experience …
It is the same as with the navdata. There are several providers, each with its own strategy, calculations, interpretations, rules, parameters, and use cases. That is why, sometimes (as you confirmed in your last posting), the weather layers are not the same across weather providers.
Look at Microsoft: there are tons of reports on different weather conditions … that should not be an excuse for such differences, but they also do their best to offer weather as real as it gets. The same here: we try our best, we fix what we can, but sometimes the root cause is the source itself (equal to the navdata).
Keep the fingers crossed that all is good now and that the different apps show the same conditions (at least roughly ).
Thanks for the kind feedback, and enjoy the sunny day (at least here in Austria)

Time synchronization issue with the “NOW” button – Charts vs. SimBrief inconsistency
Hi Richard,
Thanks for the explanation about weather providers and “the Austrian sun.” However, I need to steer this discussion back to a strictly technical issue within your software, as it’s not about “looking out the window” or differing data sources anymore—it’s about how your apps handle time.
I have found a significant discrepancy in how the “NOW” button functions across your platforms. In Poland, we are currently on Daylight Saving Time (UTC+2).
Where is the discrepancy?
In Navigraph Charts: When I click the “NOW” button, the timeline slider sets itself incorrectly. It fails to account for the local time offset, meaning the radar data is shifted by 2 hours relative to my actual current time. This forces me to manually adjust the slider every single time to see the actual rain that is currently over my head.
In SimBrief: Interestingly, your other product handles this perfectly. When I click “NOW” in SimBrief, the system correctly identifies my local time offset and displays the weather accurately.
Question regarding settings Is there perhaps a specific setting within the Navigraph Charts app that I might have overlooked, which handles the synchronization of local/daylight saving time with the radar timeline? If such a setting exists, please point me in the right direction. If not, there is a clear lack of technical consistency between your two flagship products.
As a user, I expect the “NOW” function to work intelligently and automatically adjust to the time zone, just as it does in SimBrief. Having to manually correct a slider by 2 hours to fix a software-driven time error defeats the purpose of a “Live” interface.
I look forward to a technical explanation regarding why SimBrief gets the time right while Charts remains 2 hours behind.
Let’s keep the discussion focused on the technical logic of the application rather than personal observations. I am looking for a professional explanation for this software discrepancy, not another lecture on how to look through a window.
As a user, I have every right to be mistaken, unlike you as the ‘co-author’ of your applications!
Hm, I have tested this “possible timeshift/difference” but I can´t reproduce it. The timezones are always be in UTC (Zulu). You see this in the app also in Simbrief.
Here, the Radar from 1010Z (Zulu) left Simbrief, right our charts … Exactly the same or do I miss something here?
