When the heat hits hard in 2026, the ATP aims to take action.
The ATP announced it has passed an extreme heat rule for the 2026 season.
The rule will allow for 10-minute breaks during best-of-three-sets singles matches and is similar to what has already been in place on the women’s circuit more than 30 years ago.
A new heat rule 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.

Here are some key elements of the new ATP extreme heat rule from the Tour’s announcement:
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.
