May is one of the best months to visit Oslo. Expect daytime highs around 16°C, nights near 6°C and roughly 9 rainy days across the month. One of the best months: long bright evenings, blossom in the parks and highs near 16C. Constitution Day on 17 May fills Karl Johans gate with huge children's parades, marching bands and everyone in traditional bunad dress, the single most Norwegian day of the year, so expect a packed but joyful city.

With 9 rainy days and highs of 16°C, build your May days around indoor anchors and treat sunny windows as a bonus.
MUNCH Museum
TipThe tilted 13-storey tower in Bjorvika holds the world's largest collection of Edvard Munch, including a version of The Scream shown on rotation to protect it. Book a timed ticket online in summer when walk-up queues build, allow two hours, and ride to the top-floor bar for a fjord view even if you skip the drink.
National Museum
TipNorway's largest art museum, opened in 2022 near the City Hall, gathers the national collection under one roof and holds its own painted version of The Scream in the Munch room. Book online in peak season, budget at least two hours for the scale of it, and head up to the light-filled top-floor gallery hall that is worth the climb on its own.
Astrup Fearnley Museum and Tjuvholmen
TipThis contemporary art museum sits in a wave-roofed Renzo Piano building at the tip of Tjuvholmen, with a small free sculpture park and a city swimming cove right beside it. You can usually walk in without pre-booking outside peak weekends, and even if you skip the museum the waterfront point and its beach make a fine free stop on the Aker Brygge walk.
Fram Polar Ship Museum
TipOut on the Bygdoy peninsula, this museum is built around the actual Fram, the wooden ship that carried Nansen and Amundsen to the polar ice, and you can climb aboard and walk its decks. Reach it in about 10 minutes on the summer ferry from the City Hall pier or by bus 30 year-round, and combine it with the Kon-Tiki museum next door on a single Bygdoy trip.
