Based on the weather conditions (100 degree temps almost every day) at the recent PGA held the 2nd weekend in August at Southern Hills, it is hard to imagine anyone choosing to go there the 3rd week in August because of the weather conditions!
Can you imagine playing 2 matches a day and the 36-hole final in 100-degree weather? A guaranteed recipe for heat stroke, dehydration and exhaustion! And I am not just talking about the players. The officials, caddies and spectators will melt away as well.
