Most people pack for Oslo's cold and forget the ice. Winter highs sit between -2°C (28°F) to 1°C (34°F), January lows reach -8°C (18°F), and the pavements freeze into slick sheets, so grip matters more than another sweater. Summer is a different problem, with highs around 20°C (68°F) and 12 to 15 rain days a month, so that's layers and a rain shell, not a parka.

What shoes should you pack for Oslo?
Winter boots with real tread, or slip-on ice grips over your shoes, from December to March. The streets around Karl Johans gate and the slopes up to Holmenkollen get icy, and locals take grip seriously. In summer, comfortable sneakers handle the city and the forest trails you can reach on the T-bane.
What do people wear in Oslo?
Practical and understated. Think dark colors, wool, a good down or technical jacket and clean sneakers or boots. Nobody dresses up much, but people look put together, and outdoor gear is normal city wear here.
What plugs does Oslo use?
Norway uses type C and F plugs at 230V. An adapter with an EU plug covers both. North American chargers marked 100-240V will work fine.

Leave most of your cash at home. Almost everywhere in Oslo takes cards and phone payments. Skip the cotton hoodie as your winter warm layer too, because once it's damp it stays cold, and wool or synthetic base layers do the job far better.
