Late spring with blossoming landscapes and rising temperatures, especially in the south. Good time for early-season fjord cruises and smaller crowds before summer.

Average temperature across Norway in May.
May often feels like the doorstep of summer: daytime highs frequently hit the mid-teens, meadows are lush, and boating picks up in towns like Hvaler and Arendal. This is a comfortable time to visit the Oslo Opera House roof or cycle the peninsula trails, with long daylight and fewer mosquitoes than in the high summer. Popular hikes can begin to see more traffic, so book accommodation early for weekends; a rain layer is still a must for sudden coastal showers.
May brings fresh green to the fjord-side farms and a sense of rebirth as waterfalls peak after snowmelt; daytime temperatures often reach the mid-teens on calm days. Bergen’s tourist season begins to pick up, and ferries to fjord villages are busier; however, crowds are lighter than peak summer. Packing should balance summer shirts and a waterproof outer shell - expect sudden showers even on warm days - and bring a light fleece for cool nights.
Hardangervidda, Lillehammer, Røros
May sees high-elevation snow slowly retreating and mountain passes opening; valley levels become green and wildflowers start to appear near lakes around Lillehammer. This is a quieter shoulder season: trails are wet and muddy, so waterproof walking shoes and gaiters are useful, and some tourist facilities remain limited until June. Travellers interested in cycling popular valley routes should check local conditions and ferry links.
Lofoten, Tromsø, Alta, North Cape
May is when the midnight sun begins to return in northern areas above the Arctic Circle (varies by latitude), filling Lofoten and Tromsø with 24-hour daylight later in the month and making hiking and fishing trips almost endless. Snow retreats from lower ground but remains on shoulder peaks, creating dramatic contrasts; migratory birds return and whale safaris pick up pace. Insect activity is still low, and travellers find a lively but not yet crowded scene - pack sunscreen for long daylight and a light jacket for cool nights.
Spitsbergen, Longyearbyen
May shifts toward continuous daylight for most of the archipelago as the midnight sun approaches, and coastal ice breaks up in sheltered fjords allowing the first expedition vessels and small-boat trips to resume. Wildlife viewing is excellent - migrating birds return and seals appear on newly exposed ice floes - and Longyearbyen becomes busier with scientists and travellers. Layers for both cold nights and surprisingly warm sunny afternoons are useful, plus seaworthy outerwear for boat excursions.
Norway's national day features parades, traditional dress and widespread local celebrations.
