Ooo - I'm such a laundry geek! I love that sight of washing 'cooking' in bright sunshine, and have done heaps of it this last few days. BTW think it's fine to leave it out overnight if you're sure there's no rain around and the next day is going to be sunny. (Mind you... there's nothing nicer in winter than taking a hot pile of laundry out of the drier. I'm a sad laundry-adict, I know ).
