How does the temp effect the balls why do you change from one season to the next?
As the temperature drops higher compression balls feel harder coming off the club face. I used to play Dunlop Loco's when it was cold, they were great. I still use them, but I have tried the Wilson 50 which is a 50 compression ball. It is BUTTER when it is cold. I am talking about temperatures anywhere from 0-10 Celsius. Like this morning when I teed off shortly after 8 AM the temperature was 3 C. The Wilson 50 felt fine coming off the club face of the driver, irons and putter.
Cold weather really has a big effect on the distance the ball flies. When you play in cold air the ball just does not fly as far. Yardages decrease with all clubs, so it is important to recognize that and pull the right club. If I normally hit a 7 iron I usually drop down to a 6 iron when it is cold.
No, I do not play golf in the snow. And no, there is no snow here in Ontario Canada yet

But the forecast is calling for some this week. Hopefully this cold spell passes and the weekend warms up so I can get in another round or two then.
