Did you know that the flight characteristics of your discs change based on how hot or cold they are? And how hot or cold the temperature outside is? (there’s an important distinction between those two points, which we’ll get to in a minute)

If a disc is warm, it will tend to flex a little more in your hand. The plastic (or rubber, if you’re holding a Vibram disc) will soften up and will probably feel like it has a little more grip to it. The disc will also be more apt to flying flat or turning over out of your hand. A cold disc however is going to stiffen up, in some extreme cases becoming so brittle in the cold you may even be able to crack or shatter the disc if you hit a tree or another obstacle with too much force (or hit it in just the right way). A cold disc is going to lose some of that grippiness, which may make it more difficult to throw as well.

In the cold, you also will not likely have as much moisture on your hand. While it is probably obvious that you don’t want your hand to be out-and-out sweating when you go to throw, you also generally want some moisture on your hand to contribute to the grip. ‘No moisture’ means the disc will be more apt to slide right out from between your fingers, which may mean a lack of control when you go to throw.

In the winter, the colder weather brings a much more “dead” air with it. Discs do not like to stay aloft without warm pockets of air to float on, and so discs will usually seem like they start dropping sooner than you may be used to. The disc hyzering out (hooking) early is the product of that effect, which means you can consider ALL of the discs in your bag to be more overstable during the winter months. Conversely, once warmer weather comes you will probably notice the same discs thrown the same way will fly further before dropping out of their flight. You can also usually contribute some of that to wearing less clothing, since the lack of bulk around your body means your can create a much more efficient throw and generate more power – but for the most part, the difference is simply in the air.

Many players like to throw softer plastic in the winter, like Innova Pro plastic and Discraft FLX plastic, since the softer plastic has a more natural grip for the cold weather (not to mention it’s easier to dry off than much of the “candy” champion/z-type plastic out there). Other players may throw lighter discs to compensate for the “overstability” of the discs they normally carry in their bag.

What you choose to do is up to you. Get out there, experiment, and remember to keep watching how your discs fly as the weather starts to get warm again. Not only will your discs be changing their flight pattern as you break them in, but those rising temps may make your “new favorite driver” something you retire quickly when April comes. Keep throwing, and have fun doing it!
