It'll be interesting to find out as I'll be doing similar although slightly earlier in September, because if the weather trend of recent years continues here in Cumbria, we have a good May (which we did) followed by rain till September (June hasn't disappointed) where we'll get half decent weather for a few short weeks while it cools.
Moral of the story is that the only seasonal changes we get in Cumbria is the temperature of the rain

but at least I can usually get a good deep clean in May and September time
