In reply to gavjwp: I regularly go in the summer and also have a non climbing family in tow. This year I will be there in July
I would recommend putting an add in the climbers nest (if its still open)or even the bakery next to mikes bikes. You could also put a card in one of the climbers bars and speak to Steve and Sue at galaros bar.
Keep your phone on you and check your emails.
I have found many partners in the past from all over the world, most were great company.
as for the heat, well your man above nailed it, get up early and climb till the sun hits then hit the beach. It keeps everyone happy.
Enjoy its a great place.
