Casting into a head wind can be frustrating since the fly, leader and line are most often blown back at you and miss the target. Two elements in casting are critical to deal with this situation — adding line speed and aiming close to the water. You’ll have to cast a good tight loop with more power to generate more rod bend and more line speed to penetrate the head wind. Hauling will help a lot. The added line speed won’t do it alone — you’ll need to aim closer to the water’s surface to keep the fly from being blown back off target. When stopping the rod down low in front you must stop the rod higher in back to maintain the 180 rod tip path to keep the loops tight.
Give it a try — you’ll be glad you did.
