Rain risk in Toulouse by month

The best month for exteriors
Combining daylight and rain days, July comes out ahead in Toulouse: 15h 07min of usable light against 7 mean rain days. The driest month (July) and the brightest are not automatically the same — which is exactly why the combined view matters.
For scheduling, a weather day costs more than the day itself: location availability, crew follow-on bookings and possibly the travel home. TillyGen puts the month's rain risk right next to the sun window inside the schedule — together they decide which day can happen outside.
