Rain risk in Vancouver, month by month
Vancouver averages 21 rain days in December and 5 in July. 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 Vancouver
Weighing daylight against rain days, July comes out best: 15 h 50 min of daylight, 5 rain days and 13.4 hours of sunshine a day. The sunniest month is July (13.4 h a day).
The month matters here: five exterior days run a 58 % risk of losing at least one day in July, but 100 % in December — 2 against 5 cover days for 90 % certainty.
Rain days are not grey days: even in December, the wettest month, the sun shines 3.3 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.
