The temperature of the ball does not affect the surrounding/outside air,
but it does affect the air inside the ball.
It the ball has air in it, then an increase of temperature will increase the pressure within the ball, over the short term. Over the long term, all pressurized tennis balls lose pressure. If the ball is the pressureless type, it has no air to be affected by temperature.
it decreases it
its is the air inside the tennis ball that you should be concerned with. Cold air is compressed and gives the ball less bounce, hot air is less dense and pushes on the sides of the tennis ball from the inside. Another important factor is altitude. altitude changes the amount of oxygen in the air. this doesnt change rebound it causes the ball to travel further in air.
rubber and air
A heated tennis ball bounces higher because the hot air inside the ball is lighter than the air around the ball therefore giving the tennis ball the ability to bounce higher.

Yes, of course. The material a tennis ball is made out of is porrus. That is why tennis balls go flat.

Hot. Personal experiments have shown that temperatures below 25°C make the ball bounce less. From 25°C and upwards there aren't any greater changes in height of bounce. The balls bounce almost the same.
yes Im sure it would, not necessarily warm air, but changes in pressure (air) as Im sure I can notice with my bike tyres!
Tennis balls are sold in pressurized cans so the air stays in the tennis balls. After every hit, a tiny bit of air will leave the tennis ball (also when just lying around).
when there is more moisture in the air, it is warmer and thicker. when there is less moisture in the air it is cooler and thinner. so if it is cooler temperature then it will drop faster.
