Rain risk in Zurich, month by month
Zurich averages 17 rain days in May and 11 in October. A rain day here is any day with at least 1 mm of precipitation, averaged over 2015–2024. The risk columns assume every exterior day can be lost; the cover-day column is what you need to be 90 % sure a five-day exterior block finishes.

When to shoot exteriors in Zurich
Weighing daylight against rain days, June comes out best: 15 h 55 min of daylight, 15 rain days and 11.6 hours of sunshine a day. The sunniest month is July (12.2 h a day).
The rain risk barely moves through the year in Zurich: five exterior days run a 89 % to 98 % 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 May, the wettest month, the sun shines 10.0 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.
