ATP Tour Swelters: New Heat Rule for Players
16 Dec, 2025
Summary
- ATP implements 10-minute breaks for extreme heat starting next season.
- New rule uses Wet Bulb Globe Temperature to measure heat and humidity.
- WTA has had similar heat protection rules for players since 1992.
The ATP Tour will implement a new rule next season to combat extreme heat during men's professional tennis matches. This policy will grant players 10-minute breaks during best-of-three-sets singles matches when conditions become dangerously hot, enhancing player protections in challenging environments.
The new rule is based on the Wet Bulb Globe Temperature (WBGT), a measure that considers heat and humidity. When the WBGT reaches specific thresholds, either player can request a 10-minute suspension, with matches halted entirely if temperatures exceed 32.2 degrees Celsius. Players can use this break for hydration, cooling, and coaching under medical staff supervision.
This proactive measure by the ATP follows concerns raised by players during recent tournaments, such as the Shanghai Masters, where extreme heat and humidity led to severe cramps and discomfort. The WTA has had a similar heat protection rule in place since 1992, demonstrating a long-standing recognition of the need for such safeguards in professional tennis.
