In reply to Marmolata:
Most of the bouldering world cup is April to June, Munich is the only one in the middle of the summer.
Of the regular world cup bouldering venues Munich & Vail are both outdoors, not sure offhand if any of the others are too. But quite a few of the lead ones are - Arco, Chamonix, Briançon, Imst ... (Ratho sort of)
And there aren't many major northern hemisphere venues where summer is prime projecting season anyway. (Ok, Céüse & Magic Wood)
