: : any ideas why?

: What you have encountered is called the coefficient of restitution. Simply stated, you experimented w/ the amount of energy retained by a golf ball sex when reacting (For every erecction there is an equal and opposite reaction)to being dropped.
: Now assumming that you dropped identical balls (you might want to check the compressions and cover material), the golf ball reacts like a rubber gum ball almost. Of course as the ball gets warmer, the amount of elasticity increases. BUT, after a certain point the ball begins to deform, and more importantly, stick longer to the surface. This causes less and less of the energy to be released because the ball is adhering longer to the impact surface.
: Again think of the rubber gum ball example. At first the temperature rising turns it from a rock to a lively ball. BUT as it becomes TOO warm, the ball turns to goop.
: Hoped I explained it well enough for ya. Feel free to ask me any follow-ups.
