It was blisteringly hot the second week of our trip (>30 degrees) and unless you got up very early there wasn't really any point trying to climb even once the shade had come back round - the rock retained the heat far too long and it would generally go dark before it started to cool down to anything approaching reasonable temperatures.
For the OP: If you go to Boffi, I wouldn't bother with the west facing sectors - we had a look at them but were unimpressed with the rock quality. Sector Damned is brilliant - go there instead.
If it's too hot to climb there's no shortage of other things to do - the nearby show caves are excellent, as is the Chaos de Montpellier-le-vieux and of course, if you like cheese, the Roquefort caves aren't far away...or you could just make the most of the early morning cool and spend the rest of the day swimming in the river.
