During our heatwave here in the EU, I’ve noticed that Apple is getting more and more generous in what the temperature is supposed to be. Here it is pictured side by side with the actual, measured temperature via a Kestrel 2000.
I suspect that this is AI being its usual solicitous self, continually making it better for people asking, ‘Is it cooler on the coast?’ It ain’t, by the way, same here as it is in Paris. That’s my theory, but I’m open to all conspiratorial suggestions.
It really depends on what you are comparing against. A temperature taken in direct sunlight at human height in a paved parking lot is going to be well over 10 degrees different than a grassy area shaded by a building. Even if they are adjacent areas. Proximity to a large body of water can easily change the temperature by 5-10 degrees.
A weather app is going to present a temperature that trys to average all of that for a fairly wide area.
