When you get moisture between yhe ball and the clubface it creates what is known as a flier, that is not unlike a bald tyre on a wet road.....no traction! Technically this would make the ball fly further given reduction in drag or backspin. However if your approach was too steep you could create more dig or mishit. Playing in the early morning does have other issues such as your stiffness denser atmosphere and therefore a greater drag coefficient on the ball through the air. Couple with that cold steel shafts and things dramatically slow down. My advice is to thoroughly warm up prior to play, keep a ball in your pocket and rotate each hole( even though the modern ball is less likely to be affected by temp.) use a lower compression ball, and the night before play keep your clubs inside the house to ensure shafts do not "freeze".Good luck!
