I don’t have an anemometer in my bag. But I would think I have a distinctly better idea of wind direction and speed than the average civilian. Plus I have an array of apps on my phone that I can check and regularly do for work.
With apologies to anyone that might be offended, talk of play over 35mph sustained is hard to believe. I can see fleeting gusts of 40+ being a factor. In the conditions that prompted this thread, we were seeing 30mph +/- sustained and when a few of the squalls hit, gusts of 40. This was confirmed by the father of a greenkeeper, who said they were seeing 40mph winds.
Bottom line, we were a gnats ass away from unplayable greens and if they’re rolling an inch over 8ft here, I’d be shocked. More likely 7ft or less.
The tee shots on holes 5-8 at Machrihanish in those winds rival ANY course I’ve ever played in difficulty. In calm conditions (one club wind) on a sublime twilight round last night, those tee shots are much easier but still pretty fearsome.
