Last year, the organizers of the tournament made a new model, ‘heat stress’ scale to monitor conditions for players and spectators. A score of ‘1’ is regarded as the temperature at playing conditions, whereas when the scale reaches ‘4’ players will have access to an extended break. Play will be suspended when the scale reaches the score of ‘5’.

As the temperature is more in Australia, the pressure inside the tennis ball expands. As the molecules inside the ball expand, their energy also increases, which makes the ball to bounce erratically.

On the other hand, the temperature is lesser in New York during the US Open and it further decreases during the night sessions. A decrease in the temperature causes the gas molecules to contract and move around more sluggishly. As a result, a cold ball has a much lower bounce.
