Are there any rules or stated guidelines on maximum allowable wind speeds for tennis matches (USTA or professional matches)? Or is this and other weather concerns at the discretion of the referee, chair umpire or the tournament director? I've played quite a bit in winds in excess of 20 mph with gusts close to 30 mph. however, I cannot imagine trying to play with wind speeds much greater than this. Could not find anything in the Rules of Tennis on the ITF site.
