In reply to VPJB:
It's an odd time to go to Scafell. No doubt it's possible, but it's very unlikely to be anything other than cold and wet.
Best crag in England in a heatwave though.
There will be plenty dry in the area though, I imagine Esk Buttress VSs would be OK (Medusa Wall is a great route) - others will know better than me.
