Hi!
The Norwegian foiling scene is growing, and I would guess that you will find some sweet foiling waves both outside Tromsø and in Lofoten. Hear with the people at Unstad, Lofoten. You could listen to this surfing podcast for more info about surf in Norway, Planet surf on Spotify Unsupported browser
I’we seen footage of proning from Jæren and Stad but nothing from up North. There’s not a lot of swell in the summer, but there are some.
I live in Oslo and around here we have a shortage of waves, but we try to find solutions with wing, anchorman and parawing when it is nuking 
Have nice trip
