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.
I’m aware the phone does not have a thermometer. It doesn’t seem strange to you that it’s underreporting by that much?
If that’s true, why is it different across so many platforms? France Météo is 29°, BBC Weather is 30°?
France Météo is reporting 29°. I guess I should have said that.
I’m fairly sure they try to model weather as the France Météo service reported 29°, and it changed by 5° as I got closer to the coast.
The Kestral 2000 measures air temperature. I measured it in both, but took the photo in the sun.
A Kestral 2000 is a live thermometer. Doesn’t it seem weird that Apple is off by this much.
Yes, but undereporting by 10° is a lot.
I’m genuinely surprised by the negative reaction to this post, so I’m going to try to explain why I made it.
I’m aware of microclimates, and changes in local temperature, and shade and sun and so on. I took the temperature in the shade just now, away from structures, in the garden, and it was 33°. I should have done that initially, but this was not meant to be about my being crazy. This was meant to be about the future of how we can expect temperatures to be measured and then delivered to the public.
Recently, we have had a heatwave in the EU, the 'heat dome’. You probably heard that before. Once rare, now rather common, it inverts the traditional climate where the coast is temperate and the inland is warmer.
If we are using models that ignore these new conditions, there is a risk of under-reporting actual temperatures and not taking the very serious climate emergency more seriously. The use of AI, and its documented nature of trying to please the user, concerns me in the face of gathering data for any government body trying to accurately document what is happening.
I’m sorry if I seemed crazy. I’m just concerned.
