In reply to s.thursz:
Personally I think you'll be alright, you seem to have the right idea about early starts and evening climbing.
I'd suggest walking further afield in the morning and saving the likes of Encantades for the evening. This way you can relax through the day and then have a nice easy 5 minute walk across the road.
I believe the Upped wall gets shade a bit earlier but it'd be worth checking out the local guide. It also has a few North facing crags in it and I believe Momia gets shade from about 4pm.
Desplo is excellent and certainly possible to get a whole days climbing in the shade, with no worries of the sun till 3pm onwards most of the time. There's also plenty there.
Enjoy, Emilio.
