In reply to scaredandweak:
I'd third Desplomiandia - I climbed there in September 2011 in 35+ degrees heat and it was okay. Amazing routes as well! Think there is a Top 50: 6a, 6a+, 6b, 6b+, 6c, 6c+, 7a as well as many more great lines!
When I say okay I mean it's not ideal conditions, but there's enough in the lower grades to keep you happy despite being a little warm.
