When to shoot exteriors in Mexico City
Weighing daylight against rain days, February comes out best: 11 h 31 min of daylight, 3 rain days and 10.9 hours of sunshine a day. The sunniest month is April (11.8 h a day).
The month matters here: five exterior days run a 40 % risk of losing at least one day in January, but 100 % in July — 1 against 5 cover days for 90 % certainty.
Rain days are not grey days: even in July, the wettest month, the sun shines 10.8 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.
