There isn't one answer, because Norway is 1 700 km long and the light changes more than the weather does. Pick what you're coming for and the months sort themselves out.
Calculated from latitude for the 15th of each month. This is the thing most first-time visitors get wrong: in December, Tromsø has no sunrise at all, and even Oslo manages under six hours.

You need darkness and a clear sky. Darkness is guaranteed from late September; clear skies are not, which is why we built a nightly forecast. Statistically the equinox months (September–October and February–March) are the most geomagnetically active, and February–March adds enough daylight to do something with your afternoons.
Tromsø 20 May–22 July, Lofoten 26 May–17 July, Bodø 2 June–10 July, North Cape 14 May–29 July. South of the Arctic Circle it never quite happens, but Trondheim and even Oslo have usable light past 23:00 in June.
January — polar night in the north, aurora at its darkest, cold everywhere; the coastal ship and Tromsø are in full winter season. February — light returns fast; best aurora-plus-daytime month; skiing. March — still aurora, more sun, spring skiing; a favourite. April — awkward: too light for aurora after mid-month, too much snow for hiking, but cheap and empty. May — blossom in Hardanger, waterfalls at full force from snowmelt, 17 May everywhere; fjord season opens. June — longest days, hiking opens on lower trails, midnight sun; crowds start. July — warmest, busiest, most expensive; every trail open. August — still summer, slightly quieter after mid-month, first dark nights in the north at the very end. September — the best all-round month: hiking, colour, aurora returning, prices falling. October — aurora good, weather wet, many summer operators closed. November — dark, wet, whale watching starts off Tromsø; cheapest. December — polar night, Christmas markets, aurora, and the shortest days of the year in the south.
