Whose email are you talking about. Not a chance I would pass along Berta's email so that she can get harassing emails from weak, american, little boy climbers. For now, you will just have to be satisfied with the shot in the gallery section. Although, in Eddie's case that scares me a little.
Back to the hot issue. It is all relative and you get used to the heat. I was there June July August, 2 summers ago and June to Nov. this season. I like the summer because it is more quite. Not so many people on the walls or most of the great free routes. Come Sept. expect to find people waiting in line with their haul bags on the trade routes.
Sept is the best month, but I climb in the valley all through those months. Bubu, the Italian Stalion was on freerider when we were on the Salathe in Oct, and he still felt like it was to hot, while Alex was up on the Captain all sept. and finished his route. Climbing walls at night is another nice alternative.
Even when it is really hot you can find stuff in the shade. The river will always be cool and refreshing. Agree that the weather is more unstable in the spring but often better temps. Better waterfalls then as well. Agree with finding a place at the pizza deck without waiting.
