When to shoot exteriors in Budapest
Weighing daylight against rain days, July comes out best: 15 h 36 min of daylight, 9 rain days and 12.8 hours of sunshine a day. The sunniest month is July (12.8 h a day).
The month matters here: five exterior days run a 78 % risk of losing at least one day in March, but 93 % in May — 3 against 4 cover days for 90 % certainty.
Rain days are not grey days: even in May, the wettest month, the sun shines 11.1 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.
