It is many years since I went there, but the worst visit was when the TAF was hopelessly wrong and it went below mins after I passed PNR (Aztec, positioning empty). I actually feared the engines would come off the wings in the turbulence, and it was one of the few occasions I had to sit and shake for a few minutes after parking.
Take note of mad jock's comments on turbulence - I know 'in the old days' SAS sometimes discontinued the easterly ILS down the Fjord due to extreme turbulence . A strong south south-easterly really whips the eddies off the rock pillars.
As said, fantastic scenery, great people. 99% chance you'll enjoy your visit.
