When to shoot exteriors in Hamburg
Weighing daylight against rain days, June comes out best: 17 h 01 min of daylight, 11 rain days and 12.0 hours of sunshine a day. The sunniest month is June (12.0 h a day).
The rain risk barely moves through the year in Hamburg: five exterior days run a 87 % to 96 % risk of losing at least one day, whatever the month. Choosing the month buys you little here; cover days and a flexible schedule buy you more.
Rain days are not grey days: even in July, the wettest month, the sun shines 11.5 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.
