Noted and logged. Especially past around 500 yards. I've seen wind blow in two or three different directions at the same time at distances past 700 out to 1200 yards, and if you don't have range flags, it is a guessing game. I've also seen wind direction change drastically between shots on some of the ranges I've shot on, especially in Colorado and here on the Panhandle of Texas.
I can only say this because I had 7 witnesses.
the short version is I had a brand new CZ 527 .204 Ruger I'd been gifted by the CEO who I guided and consulted for on various firearms they wanted to bring to the US Market.
We're quail hunting about 40 mi west of town and around 11 a.m a big front blew in from the west NW.
Within minutes the winds are gusting 40-50mph.
We call lunch and load up into two vehicles.
Just as we lock the gate and turn east on the Highway a coyote breaks into a dead run heading NE with the wind almost exactly running tail to head.
One of the guys says, "Hey CR why don't you shoot him", I say "not in this wind," he repeats and say what the heck.
By the time I get on him he's easily at 350 still running about 35mph or so.
I try to figure the wind in my head along with the drop and just miss him right above his nose.
He of course immediately kicks it up to about 50mph, I throw another one in.
I figure by now the wind and the speed are pretty much a wash put it just above the nose and pull the trigger.
He cartwheels to the edge of the brush surrounding the Wheatfield.
We measured it at 540 yards from the door to the coyote and I figure he covered about 12-15 yards of that distance after being dead with a perfect hit just below the crown of the head and no exit. Customer wanted the head and hide to decorate his coffee table so he could always remember the event.
A customer who was along is describing this event to one of our local "experts" who was to say the least a rather unpleasant fellow a couple of years later, to which the expert replies, "Just a lucky shot, the coyote must have run into the bullet". Customer chuckles and smiles and says, I've been hunting with him for ten years, he gets lucky a lot.
Expert tucked his tail and retreated to his table and never bothered us again.
