The man in the article commenting that his father could no longer read the weather because the signs were wrong is my personal experience too - I've been tramping and hunting in a particular area of our Southern Alps since I was a child, and everything I learned about predicting the weather there when I was young doesn't work now. It used to be that autumn was the time of year with the most stable weather - lots of clear skies, no rain, so ideal for crossing rivers.

But now there's a lot more northwest winds in autumn, which causes heavy rainfall that floods rivers. And likewise, the spring "monsoon" when continual nor'westers are the defining weather pattern (when I lived in an alpine village, 29 days of continual rain in November was the usual) now extends significantly into Summer. And of course, the rainfall events are getting more extreme, damaging roads and hiking infrastructure - like this: https://www.odt.co.nz/regions/fiordland/routeburn-closed-for...
