ATP Adds Heat Rule for 2026
The ATP approves the introduction of a new heat rule, based on the Wet Bulb Globe Temperature.
The ATP Tour will add a rule to address extreme heat during matches in 2026. 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.
The ATP Board’s approval of the new policy was announced Monday.
