Wrong info shown?

[daath]

I am new to HA and to all this, so please bear with me.

I added my weather station, but it displays pretty weird stuff. In the middle of the day it will say "Cloudy, night" and right now "Rainy" - and it's very sunny with a few very scattered clouds. Also why would it say it's night when it's in the middle of the day?

This is my station: https://www.wunderground.com/dashboard/pws/IKASTR5

The forecast page: https://www.wunderground.com/weather/dk/kastrup/IKASTR5 - says "Fair" - but my HA card says "Rainy" ...

Am I doing something wrong? The entities look ... normal, I guess :)
