When to shoot exteriors in Athens
Weighing daylight against rain days, July comes out best: 14 h 33 min of daylight, 2 rain days and 13.6 hours of sunshine a day. The sunniest month is July (13.6 h a day).
The month matters here: five exterior days run a 28 % risk of losing at least one day in July, but 82 % in January — 1 against 3 cover days for 90 % certainty.
Rain days are not grey days: even in January, the wettest month, the sun shines 7.3 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.
