Apple Weather forecasts for my area have shown a 30-50% chance of precipitation for eternity, even when there isn’t a cloud in sight. My meteorologist has told his readers to ignore Apple’s forecasts.
This started around the time the Apple Weather outages a few months ago and haven’t improved. YSK that you can report inaccurate forecasts from within the app, but it hasn’t improved for me.
I’m currently using Foreca on iPhone and the free version of Carrot on Apple Watch.
I’m in Queensland, Australia, and it seems to say there’s no chance of rain at all, as there’s thick clouds above my head seconds from drenching me, and sure enough, I start getting drenched.
