Best: Jun-Jul · Great: May, Sep
The year swings from a cold January to a hot, humid July, with rainfall concentrated around August — usually the least comfortable stretch of the year. In July, expect highs around 22°C with rain on roughly 10 days of the month.
Oslo's Vigeland Sculpture Park and the Viking Ship Museum are good city-based stops, but Norway's real draw is the fjords further out — a day trip on the 'Norway in a Nutshell' route via Flåm covers dramatic scenery by train, boat, and bus in a single day.
Try fresh salmon, brown cheese (brunost), and traditional fish stews, especially around Oslo's harbor restaurants.
