Question 4

What are the sunniest months in Oslo?

Accepted Answer

Oslo's sunniest month is May, which recorded 355.2 hours of sunshine in 2024, averaging approximately 11.5 hours of daylight per day. This makes late spring the ideal time for visitors seeking long, bright days in the Norwegian capital.

The top three sunniest months in Oslo during 2024 were:

- **May:** 355.2 hours of sunshine

Summer months from June through August provided a combined 738.6 hours of sunshine, accounting for 36.7% of Oslo's annual total of 2,012.6 hours.

The average temperature during this period was 6.5°C (43.7°F), dropping from a mild 11.7°C in September to near-freezing 0.7°C by November.
