When to shoot exteriors in Berlin
Weighing daylight against rain days, June comes out best: 16 h 48 min of daylight, 10 rain days and 12.5 hours of sunshine a day. The sunniest month is June (12.5 h a day).
The month matters here: five exterior days run a 74 % risk of losing at least one day in September, but 93 % in January — 2 against 4 cover days for 90 % certainty.
Rain days are not grey days: even in January, the wettest month, the sun shines 3.0 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.
