Comment on Apple generously 'reducing' live temperatures by almost 10°C
vk6flab@lemmy.radio 3 hours ago- The temperature on the phone is likely an official temperature, measured at a specific location, under very precise conditions.
- The thermometer is in full sun, which is not at all either standardised, nor under any controlled conditions, for example, you’re holding it and your temperature is 37°C.
Temperature is measured like this:

If that’s true, why is it different across so many platforms? France Météo is 29°, BBC Weather is 30°?

Because they’re likely not all using the same data. Some will be time delayed, from a different weather station, averaged over a different period, any number of variations.

So measured at a specific location, under very precise conditions, but also time delayed, from a different weather station, averaged over a different period with any number of variations.
This app is very popular with people, it’s where a lot of Apple users get their information. I guess it doesn’t bother you people giving out information that is this wrong.
It bothers me.

It bothers you because you have no understanding of how temp is measured/calculated by these different platforms.
This is new - in the 70’s the local news station would report local temp, and it would be wildly different from the thermometer on our property, because local conditions can vary that much.
I can feel the difference in temp where I live by walking 30 feet. It can vary 20 degrees in that time because microclimate.
Weather apps are notoriously wrong for me - at least 5 degrees F all the time.

I mean the fact that different sources show different results is your answer.

Because they have different computing models, using different data, collected at different times.

That’s a negligible difference. Also the sources might use different prediction models. The temperature on the apps is the predicted, not the actual temperature. Go to your local airport website for actual temperature readings (at that location).
