Any suggestions on how warm or cool clothes one should bring? There'll be one day we're in the North Cape a few hours, and a hike in the Lyngen Alps. Also Bergen, Norway in a Nutshell, Gerainger, Molde, Lofoten. Thank you!
Layers. My Norway trips have been early Easter (February) to late Easter (early April) trips. Weather during these late winter/early spring trips were relatively mild from single digit minus C to +10C and blue sky to precipitation.
The DNT's summer hiking list is a good start in that even summer nights can be cool:
wool, part wool or synthetic underwear
wind jacket/anorak or all-weather jacket
shirt or light sweater of wool or fleece
And its good to have synthetic tee-shirts and shorts for warm weather.
