What is Reddit's opinion of Yr.no?

From 3.5 billion Reddit comments

yr.no. Da ein wenig durchklicken und du findest eigentlich alles. In der stündlichen Übersicht auf Details gehen. Die Karten auf "World" stellen, dann ist Deutschland auch in den Vorhersagen mit drin.

Get a paper map of southern Norway and use it to decide on ferries or not. Googlemaps is the best digital map, but use a large map for overview. Ferries are sometimes great timesavers and sometimes boring. I've driven extensively all over southern Norway. You will have a good time and find interesting places and photo ops many places. Don't be to ambitious, Talk to people and check the weather https://www.yr.no/?spr=eng. Also warm clothing, wool for the entire body, warm boots and wind (and water) proof outerwear. Have blankets, snowshovel, snacks/food and drinks in the car. You might get stuck or have to wait for a convoy in the mountains. Fill up the tank frequently and try to keep it at more than half. Be careful, enjoy and have a great adventure

You'll definitely get some lovely scenery going that route! I think the wind and the sea air has taken most of the snow on the coast, but I haven't checked much yet.

For weather info, the most accurate for Norway seem to be yr.no (link is for the english version). It's what I use.

Bodø might still have quite a bit of snow when you get there. The mountain'y areas carry snow for quite some time. Easter is when people go on ski trips, though it is a late easter.

You're still not saying anything specific so I'll answer non specifically.

Depends on the altitude.

Bonus: Check this site and search for the locations you are going and select statistics. This will give you a general idea of what that weather was previous year for that time but that will give you a general idea but be aware that the weather can be very unpredictable in the mountains.

According to professional photography mates of mine the norwegian weather bureau Yr is the best one. It's the default site they use to check the forecast since it's almost always pretty damn accurate.

Ah, fair enough. Then definitely check the weather reports when you get into the country, and perhaps also consider the opening hours of things you might want to see in Oslo as well.
