Rain risk in Copenhagen, month by month
Copenhagen averages 13 rain days in January and 9 in April. A rain day here is any day with at least 1 mm of precipitation, averaged over 2015–2024. The risk columns assume every exterior day can be lost; the cover-day column is what you need to be 90 % sure a five-day exterior block finishes.

When to shoot exteriors in Copenhagen
Weighing daylight against rain days, June comes out best: 17 h 30 min of daylight, 10 rain days and 12.8 hours of sunshine a day. The sunniest month is June (12.8 h a day).
The month matters here: five exterior days run a 83 % risk of losing at least one day in April, but 93 % in January — 3 against 4 cover days for 90 % certainty.
Rain days are not grey days: even in January, the wettest month, the sun shines 2.9 hours a day on average. Many of those rain days are wet for an hour, not all day — if your scenes can wait out a shower, lower the share slider in the tool.
