well, I just played an alt shot game at Kiawah and the wind was never more than 10 mph. On some holes it was 1 - 3 mph. How is that possible?
It's not very breezy at Kiawah. Bethpage is farily calm, too.
But, St. Andrews and RSG, even with light wind, will have breezes of 8 - 18 mph or so. Chambers Bay, Wolf Creek, and Pebble are not far behind.
Congressional, Oakmont, and Merion are pretty much in the middle.
"Light wind" doesn't mean the same mph on each course --- neither does "heavy."
