Cómo reaccionan las pelotas de tenis al clima
The tennis ball does not always behave the same way. Variations in temperature, altitude, and usage time change its internal pressure, directly affecting bounce, speed, and control.
Temperature
Heat expands the air inside the ball, while cold contracts it.
- Hot day: faster, lighter ball with higher bounce
- Cold day: heavier, slower ball with lower bounce
👉 Impact: on hot days, the ball flies more than expected; in cold weather, it requires more force for the same effect.
Altitude
At high altitudes, external pressure is lower.
This makes the ball:
travel faster
bounce higher
👉 Impact: without adjustment, it’s common to lose depth and control.
Usage time
New balls: more pressure and response
Used balls: less bounce and slower speed
👉 Recognizing when to change the ball helps choose safer shots.
Warming up the ball
Attentive players warm up the ball before key points, spinning it in their hand or bouncing it lightly on the ground.
👉 Advantage: more predictable response on serves and returns.
Practical rule
- Adjust power and spin to the conditions
- Be more patient in cold weather
- Use more spin in heat
💡 Summary: those who understand ball pressure play with physics on their side.
