ATP Set to Roll Out New Extreme Heat Rules Starting in 2026

Under the revised framework, the ATP will introduce clearer thresholds for extreme heat, expanded cooling measures and more structured medical interventions during matches played in high temperatures. The policy is designed to create consistent standards across tournaments, giving players better protection while maintaining competitive integrity. Officials say the changes reflect ongoing dialogue with players and medical experts, as well as the realities of a warming global climate.

Why the ATP Is Changing Its Heat Policy

Extreme heat has become an increasingly common issue on the professional tennis calendar, particularly at summer events and tournaments played in hotter regions. Players have frequently raised concerns about dehydration, heat exhaustion and the cumulative toll of long matches played in punishing conditions.

The ATP’s new policy is a response to those concerns, aiming to move beyond ad-hoc measures and create a unified approach. By setting clearer guidelines, the tour hopes to reduce uncertainty for players, officials and tournament organisers when temperatures rise to dangerous levels.

What the New Rules Will Include

From 2026, matches played in extreme heat conditions will be governed by updated protocols that prioritise player health. These include more defined heat thresholds that trigger mandatory breaks, extended changeovers, and additional cooling opportunities such as ice towels and shaded rest areas.

Medical staff will also be given clearer authority to intervene if a player shows signs of heat-related distress. The ATP believes this structured approach will help prevent serious health incidents while still allowing matches to be completed whenever it is safe to do so.

Player Welfare and Competitive Balance

One of the key goals of the new policy is consistency. Players have previously experienced different heat rules depending on the tournament or region, which has led to confusion and frustration. The ATP wants to ensure that athletes face similar protections whether they are competing in North America, Europe, Asia or Australia.

At the same time, officials stress that the changes are not intended to alter the nature of competition. Matches will not be shortened automatically, and decisions will still balance player safety with the integrity of the sport.

Looking Ahead to the 2026 Season

With the new heat policy set to begin in 2026, tournament organisers now have time to prepare and align their facilities and staffing with the updated requirements. The ATP will continue working with players, coaches and medical professionals to refine implementation details over the coming months.

As climate challenges increasingly affect outdoor sports, the ATP’s move signals a broader shift toward proactive player protection. The success of the new policy could also influence how other tours and sporting bodies approach extreme weather in the years ahead.
