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.
