back in the time, they used the ATIS as the source for the dewpoint, Then they got a problem for having a static dewpoint at 10 (freezing conditions below 0), THEN they switched to a new source and never fixed the dewpoint. All of that instead of fixing the first problem

Yes, when i check the weather debug tool the dewpoint does not match neither METAR or ATIS though. Ă think dewpoint comes from Meteoblue data. Nothing wrong with that. Only want to let you know And it feels like dewpoint canât be same as temp. I wonder why. Were some time since i checked. They may have changed that now. I can check later and update if needed?
Edit: as i expected. Not the value from METAR is injected for dewpoint, only temp.
Temp=8
Dewpoint=6,7

I believe we see dewpoint the same as temp only because we are looking at a round number.
It is said that dewpoint canât be higher than temp, so my guess is that it will tend to infinity and never reach the actual temp.
But your guess is good as mine >.>
You canât have dewpoint higher than temp because when theyâre equal, you have 100% relative humidity. If the dewpoint was higher than the temp, then youâd have humidity greater than 100%, which canât happen. When you have 100% and introduce more moisture, the only thing that happens is fog due to water vapor condensing in the air.

Yes, or itâs raining.
The photo there is an excellent example of what a trainee pilot starting out might see on a first lesson. The dew-point aka wet-bulb temperature is a very important factor in aviation meteorology. It can determine icing conditions in IFR, and lack of engine performance even at sea level with naturally aspirated (NA) engines.
Especially important when you consider what may have been a dry runway and low humidity suddenly becomes a wet runway and high humidity.
Just imagine doing terrain avoidance somewhere like Indonesia. That is a major reason CFIT is so bad in such places. Hot, damp and relatively high elevation should ring alarm bells if you are flying with a NA engine. Maybe better to land the Cessna flaps 10, as if the flaps fuse blows at flaps 30 you most likely wonât have much climb performance.
Flaps 10 is ok to be stuck with as it isnât too draggy.
Personally, I use the Atis on the radio, I donât like all the extras provided through âwindowsâ.
Maybe a habit though it feels more natural too.
Iâm glad to see the concern being taken care of.
The devil is in the details.

The interesting part of this is we have 3 different values in the sim. Debug report 12.2, ATIS report 10 and METAR report 14 in this case. What value is the correct value that is actually happening in the sim?

Have you disabled/removed all your mods and addons? If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the Community Support section.
Yes. I tried both with and without addons.
Brief description of the issue:
When using live weather, the dew point value is always reported as âone-zeroâ in ATIS and AWOS regardless of the actual dew point in the METAR.
Detailed steps to reproduce the issue encountered:
- Create a flight at an airport that has ATIS or AWOS. 2. Use live weather. 3. Tune the aircraft radio to ATIS/AWOS. 4. Compare the reported dew point with the current METAR.

OMG, so this bug is year-old⊠Funnily, I couldnât find this thread using the forum search.
This bug has been around since the beginning of the sim. I donât remember the ATIS/AWOS ever saying anything other than 10°C. To the point itâs a meme in my streams where I mouth the words when it comes up. And it seems like itâd be such an easy fix.
This is ridiculous. Nice morning in Anchorage. Metar says both Temperature and Dewpoint around -10°C, clear sky. But AWOS/ATIS is saying dewpoint plus 10°C. Of course this means extreme icing conditions which is abysmally wrong and is a huge bug. Will Asobo finally fix it, please?!

Hey Asobo WAKE UP. It still does not work. No matter the realistic value atis always shows dewpoint 10 °C
In 2024, Iâve found itâs no longer stuck at 10C, however if temps or dewpoints are negative, the minus is being shown in the text, but not being spoken in the broadcast.
Are you using 2020? I have a feeling itâs not fixed there.

MSFS2020. Metar message opened in game shows it correctlym but atis message always shows and read dewpoint 10. So it is hard to choose if in game it is 10 or different number. There is no way how to prove it.
