They do consider wind. Too much tail wind can invalidate a world record.

That's one factor in one sport.

Does anyone disregard a track world record because the weather was pleasant that day, and the previous recordholder did it on a hot, humid one? Does anyone argue Barry Bonds' home run title should be disregarded because of the thin air at his away games in Denver?

Take away wind assistance, and Bucky Dent loses his place in history. Take away a pebble in the grass and the Red Sox win the 1986 World Series. Add some rain to give pitchers an extra day of rest, and all sorts of baseball history gets upended.

To an extent. Road race world records are only valid if they fall within certain limits of elevation change. You can run slightly downhill, but can't descend 500 meters. Ditto for tailwinds, I believe.

Wind speed is accounted for in athletics. Records won't get validated if there is a strong tail wind.

This seems to be the only somewhat common variable.
