Professional tennis requires ideal conditions. Even a small deviation from the standard can give one player an advantage and kill the chances of another. What are considered "comfortable conditions" for organizing Grand Slam tournaments and the Masters series in 2026? Let's go through the points.

Covering

Clay (Roland Garros): ideal humidity to prevent dust but not slippery. High bounce. Hard (US Open, Australian Open): the surface must provide a consistent bounce without "dead zones". The surface temperature is regulated to prevent melting of soles. Grass (Wimbledon): a nightmare for organizers. An ideally smooth surface without bumps is required. Irrigation is strictly metered.

Humidity and air temperature

Ideal temperature for play: +20...+24°C. Humidity: 40-60%. High humidity makes the ball heavy, causing players to tire faster. Australian Open often plays in the evening and at night to avoid 40-degree heat.

Lighting and wind

In 2026, all central courts are equipped with LED lighting without a strobe effect. Brightness is regulated for evening sessions. Ideally, there is no wind. Therefore, stadiums are built with high walls and canopies (like on the Philippe Chatrier Stadium).

Auditory comfort

The stands should not create an echo. Wall materials absorb noise so that players can hear the ball bounce. Drums and whistles, like in football, are prohibited. The requirement for acoustics: the judge on the tower must hear the players without a microphone.
