Golf balls mainly travel further in summer because there is less air density in warmer weather for the golf ball to fight against.
Golf balls also fly further in high altitudes mainly due to the change in air density, which decreases as elevation increases.
When the golf ball and golf club are colder, the transfer of energy is not as efficient, so the ball speed will be less.
Colder air is more dense than warm air, so there is more friction and drag.
Also human muscles are more flexible and responsive when the temperature is warm which helps the efficiency of the golf swing.
