In reply to red.stiletto: Hi, I was in Spain last June, first couple of weeks and had beautiful weather. Was indeed quite hot, but just means that you have to go early morning, long siesta and back late afternoon when walls are in the shade. I climbed at Guadelest with a local Spaniard and there were lots of Spanish climbing there, but no one else which was great! There is a nice climbing refuge there that does lunch and sells cold beers, ideal for the siesta!
Also climbed near Lliber in the Jalon Valley and Alcalali, both in early evenings and was fine. Nice temperature and no one else about apart from a couple of Spanish climbers. Would definately take the climbing gear, enjoy!
