Context

Our verdict

Oslo is one of Europe's most natural capitals: forests 15 minutes away (Nordmarka), 40 islands in the Oslofjord. June-July are my favourite months (7.6-7.7/10): 12-21°C, 40-42% rain, 18h days, swimming at the fjord islands (Hovedøya by ferry from Aker Brygge), festivals (Øyafestivalen early August).
