At first I thought something was wrong with my swing, but then a friend mentioned I could be losing distance because it's cold. The past few times, I've been going when it's about 45* outside. My approach shots are coming up short. Usually from 160 I'm hitting a 7, but I've had to hit 6 and sometimes 5 to get it on or near the green. I'm really getting frustrated thinking it's my swing.
Could I be losing 10 to 20 yard because it's 45 degrees (F) outside?
