Best time ...
Hard to say when the weather is best for Norway;
on all six trips I've had good weather, but the trips earlier in the summer, end of june, first two weeks of july, were a bit colder, especially at night the temp regularly dropped to freezing point.
The warmest days I had end of july start of august.
The rain is another thing... Pure luck I guess...
This year my brother left one week earlier and had some bad weather that first week.
Last year a friend of my left one week later then me and travelled north with the bad weather while we came south with the warmth...
Three years ago my sister had fresh snow on the Gammle Stryn Veijen near Geiranger and a week later I took that road with clear blue skies and 25 degrees celc.
More interesting when planning when to go is perhaps
looking at the ferry charts for high and low season (costs!),
and the start/end of the hollidays in Germany (traffic jams near Hamburg, waiting times at the ferries)
When interested in seeing the midnight-sun then end of june, beginnning of july is the best time the be north of the arctic circle.
Even with rainy weather Norway is doable because of the good camping places; most camping places have an inside kitchen and dining-room, and huts can be found on every route...
