When to shoot exteriors in Los Angeles
Weighing daylight against rain days, June comes out best: 14 h 25 min of daylight, 1 rain days and 12.3 hours of sunshine a day. The sunniest month is July (13.1 h a day).
The month matters here: five exterior days run a 15 % risk of losing at least one day in July, but 78 % in March — 1 against 3 cover days for 90 % certainty.
Rain days are not grey days: even in March, the wettest month, the sun shines 10.2 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.
