Pretty entertaining to do a Google seach of "Prevailing Wind at the Old Course"
Apparently Melvin agrees with David Kidd about something. From the 7th at St. Andrews:
"A prevailing wind at St. Andrews is a golf oxymoron, like the metalwood."
However - this website opines such a thing exists at St. Andrews but suggests it is the opposite direction as my guess:
"The prevailing winds blow east to west and can severely impair distance."
http://www.standrewsgolf.com/golf-courses/This website is consistent with my impression:
"Surprisingly, to me, the dominant wind at St. Andrews is from the West, ..."
I will need to look at a map for this one but does it mean North?
"The 11th hole shares its double green with No. 7. This hole typically plays into the prevailing wind off Eden Estuary."
http://golf.about.com/od/golfcourses/ig/Old-Course-Pictures/Old-Course-at-St-Andrews-11.-Na5.htmFrom an ESPN 2005 Open Preview story:
"In July, the prevailing wind comes out of the quarry next to the airfield -- from the southwest -- roughly 75 percent of the time. That means holes one through seven and the 10th and 11th generally play into it. Nos. 8 and 9 and the 12th through the 18th generally play downwind. In addition, the tides affect the severity of the wind. An incoming tide is generally on an easy breeze, it goes dead calm as it turns and picks up intensity as the tide goes out. However, this notion of "generally" is where it all comes a cropper. If the weather turns a bit freakish, well, the wind can be the exact opposite, coming out of the northeast or north, so you can flip which holes play with or into it. And that can happen quickly. Says Peter Dawson, chief executive of the Royal and Ancient, "There is a prevailing wind, but it never comes from there." In the unluckiest of scenarios, it is possible for someone to go out into the wind, have it turn the same time they do and come home into the wind. That's considered a generally bad day. "St. Andrews is St. Andrews, man," says Ernie Els. "It can be very nice and it can be a beast.""
