Comment on Apple generously 'reducing' live temperatures by almost 10°C

  1. The temperature on the phone is likely an official temperature, measured at a specific location, under very precise conditions.
  2. 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.

      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).

  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.

  Apple “overreports” on mine. Because they get their temperature from the business park down the hill. It’s cooler where I am.
