ATP introduce new heat rule effective from 2026
Baku, December 16, AZERTAC
The ATP Board has approved the introduction of a new heat rule that will come into effect from the 2026 season, aligning the ATP’s approach with that of the WTA and strengthening protections for players competing in extreme conditions, according to the ATP Tour’s official website.
The new regulation is based on the Wet Bulb Globe Temperature (WBGT) and introduces clear thresholds for cooling measures and suspension of play in best-of-three singles matches.
Key Provisions are as below:
10-Minute Cooling Break
Cooling measures will be implemented when the WBGT reaches 30.1°C or higher during the first two sets of best-of-three singles matches. When activated, a 10-minute cooling break after the second set may be requested by either player and will apply to both players in singles.
During the break, players may utilise cooling measures, hydrate, change clothing, shower and receive coaching, under the supervision of ATP medical staff.
Suspension of Play
Play will be suspended when the WBGT exceeds 32.2°C.
Player Health and Safety
The new heat rule provides a structured, medically supported approach to managing extreme heat, with the objective of safeguarding player health, while also improving conditions for spectators, officials, ball persons, and tournament staff.
