The Weather app in iOS 15 is also getting a pretty substantial redesign, with a whole new set of data and layouts that will change based on condition, along with a variety of new weather graphics and animations.
This will include data such as wind speed and direction, UV index, barometric pressure, air quality, precipitation, and more. Each of these data points will be shown in a separate tile that provides more detailed info.
The backgrounds in Weather will also feature richer animations that will show details such as sun position, cloud cover, and precipitation specific to your location.
Lastly, Apple is adding full-screen high-resolution weather maps that will include temperature, animated precipitation, and air quality information.
