Overview
- The policy will apply across ATP Tour events in 2026, while Grand Slams and Olympic tennis will continue under their separate heat protocols.
- Players may request a 10-minute cooling break when the WBGT reaches at least 30.1°C during either of the first two sets in best-of-three singles.
- Play will be suspended when the WBGT exceeds 32.2°C to reduce the risk of heat-related harm.
- During the break, players can change clothes, shower, hydrate, use other cooling methods, and receive coaching under ATP medical supervision.
- The decision follows incidents in Shanghai that included Jannik Sinner retiring with severe cramps, Novak Djokovic vomiting during a match, and Holger Rune publicly protesting the conditions.
