Background & outlook
Current conditions and the 14 day forecast
Oslo lies in Norway, an area with a cool maritime climate: mild for the latitude but wet and windy, with long summer days and short, dark winter ones. That is exactly why a two-week outlook is useful here — it shows the pattern rather than one snapshot.
It is currently 19°C in Oslo with light drizzle. It feels like 19°C, humidity is 85% and the wind is SE 15 km/h.
Today (Saturday) reaches a maximum of 19°C and a minimum of 16°C, with 12.3 mm of rain and 0.8 hours of sunshine. Sunrise is at 06:05 and sunset at 20:30.
Tomorrow (Sunday) the maximum temperature in Oslo is 18°C and the minimum 16°C. Around 0.7 mm of rain is expected with 1.5 hours of sunshine, and the chance of rain is 97%. The data is refreshed several times a day through Open-Meteo.

A daily rainfall total says little on its own: the same 5 mm can be one short downpour or a grey day of drizzle, which is why the hourly chart above is often the more useful of the two. Over the next fortnight the highest UV index for Oslo is 4, which is low to moderate.
The first three to five days are generally very accurate. After that the certainty drops off and it is better read as a trend than as an exact daily prediction. Our data comes from Open-Meteo, which combines national weather models — among them the Met Office, DWD and ECMWF — and recomputes them several times a day using measurements from stations worldwide.
