When you are on the court and the wind picks up, assess the situation: the direction, strength and variability of the wind. Is it in your face, at your back, coming from the side, shifting, swirling, gusting, all of the above? Also, make certain to practice from both sides of the net, and both sides of the court. Practice a full array of shots, being certain to include 3rd shot drops, dinks, delivering and receiving lobs. BEWARE, wind can affect the ball throughout play: After your opponent hits the ball, as the ball bounces, after the ball bounces, as you hit the ball, and after you hit the ball.
