I always recommend using your country's state weather agency website. It will probably be the most accurate, and you can often get real time readings from the agency's sensors around the country.
In my case, because I live in Spain, I use AEMET.
the OSS Weather app on Android has been pretty good for me this last year. Seems it's using open-meteo as default provider.
Weatherspark is great for weather trends and comparing locations. Doesn't do daily forecasts anymore though.
Multiple people have recommended https://yr.no/ to me recently. It's Norwegian but effective everywhere.
Came here to suggest this. As a norwegian I have been using it since forever, but I wasn't aware of how good it is for outside of Norway too until a friend of mine, who then worked with them mentioned that they had a surprisingly large user base from one African village.
I travel a lot for a living, so I often use it for places I am headed to on the other side of the world.
It's run by the norwegian metrological institute, so their model is based on the same data you'd have with paid services.
I usually go to wunderground.com
It was so much better before The Weather Channel bought it.
accuweather is not too bad on website using desktop but don't bother with the app, it's horrible, ads etc
Y!天気 Not because it's particularly interesting, but it's more accurate than others that I've tried.
