I usually try to avoid climbing in extreme heat but if I do climb here's a few tips.
Pick climbs that are going to be in the shade in the afternoon. Up at Moonarie we were able to climb in the shade all day
start early/finish early,wear long sleeve shirt and trousers if in the sun, avoid multi-pitch climbs that are going to be in the full sun (no escape), cliffs near water are often good (for a swim when it gets too hot).
Another good trick is head back to camp and crack a cold beer. |
