In reply to Gelli:
Was there in April couple years ago weather was mixed but some hot sunny days
Frontalas Bajas, Los Albercones you can sit and belay under the shade of the pine trees, though if your climbing you end up climbing out of the shade, Sector Castrojo had shade first thing in the morning not sure how long that would last in August though.
Desplomilandia shaded most of the day from the guys and girls that climbed there.
Rocabella North Side shaded. And handy for Rocabella resturant a drink and snack after where we stayed for our week
