I don’t like it, it’s another exercise in taking a functional website and ‘modernising’ it by making it look like a mobile app (i.e. the make it look attractive to kindergarten kids school of design).
For my own use cases it’s made it more annoying to get to the 7 day Canberra forecast, made the local radar harder to see, and I’m not noticing a link to the written ACT region forecast which I will want to look at in winter.
New layout is way easier to view on my phone. current temp, feels like, max temp, rain ml all immediately visible for my local area. And a big old button to push me down to a scrollable rain radar. Easy.
