The day before I played it was about 33 degrees Celsius (90 Fahrenheit). Apparently someone said that with those temperatures in the air, the temperature on the ground would be 42 Celsius (107 F) and that is exactly the threshold where the grass would die. Perhaps someone more knowledgeable than I can comment on that?
In any event, on the day I played, the temperature was 23 C (73 F) max and quite humid. No direct sun, a lot of water in the air. And on that day they watered so much that there was standing water(!) on the course. I did not have my waterproof shoes on as I reckoned it hasn't rained in quite a while and wasn't going to - but my feet got completely soaked. At 2 PM on a July's day my trolley was still making visible tracks on the fairway, something I am accustomed to seeing on a dewey autumn morning.
The Pro even commented that my greenfee supplement was well worth it in his opinion, because of the lush and green fairways - something, he said, that not many clubs can produce in the summer. Well, lush they were, those blades of grass - thick and long! For the life of me I cannot understand why anyone would prefer damp semi-rough to firm fairway.
