Australian Open Adjusts Schedule for Extreme Heat & Player Safety

MELBOURNE, Australia – The Australian Open is adjusting its schedule and implementing preventative measures as temperatures are forecast to reach approximately 100 degrees Fahrenheit (38 Celsius) on Saturday. Tournament officials have moved up start times and altered match placements in response to the anticipated heat.

Responding to Extreme Conditions

The changes include moving the start time on major courts to 10:30 a.m., an hour earlier than usual. This adjustment aims to reduce player exposure during the hottest part of the day. An additional match has been added to the Margaret Court Arena schedule, utilizing its covered structure to provide relief from the sun.

Did You Know? The Australian Open introduced the Heat Stress Scale in 2019, considering air temperature, radiant heat, humidity, and wind speed to assess player risk.

Kia Arena, which lacks a roof, will host only three singles matches instead of the originally planned four. This strategic shift prioritizes player safety by limiting exposure on the open-air court.

Heat Rules and Player Welfare

The tournament employs a Heat Stress Scale (HSS) to determine when to implement breaks or suspend play. A reading of 4.0 on the HSS triggers 10-minute breaks for women’s and junior singles, and 15-minute breaks for wheelchair singles. Men’s singles players receive a 10-minute break after the third set at a reading of 4.0. A reading of 5.0 could lead to the suspension of matches on outside courts.

The Australian Open’s HSS is described as more accurate than previous Wet Bulb Globe Temperature (WBGT) readings. The ATP introduced a heat rule in 2026, allowing players to request a 10-minute cooling break if the WBGT reaches or exceeds 86.1 degrees. The WTA has had a heat rule in place since 1992.

Expert Insight: The adjustments to the Australian Open schedule demonstrate a growing awareness of the physical demands placed on athletes and the need to balance competitive integrity with player health and safety in the face of increasingly extreme weather events.

Players like Jannik Sinner, who has previously struggled in hot conditions, will be tested by the heat on Saturday. He is scheduled to play Eliot Spizzirri, who recently completed a demanding five-set match. Other players, including Madison Keys, Jessica Pegula, and Novak Djokovic, are also slated to compete under the challenging conditions.

Looking Ahead

While temperatures are expected to subside on Sunday and Monday, a return to even hotter conditions is forecast for Tuesday. This means players who advance, such as Carlos Alcaraz and Aryna Sabalenka, could face similar challenges early next week. World No. 1 Aryna Sabalenka acknowledged the difficulty, stating, “I wouldn’t like (to) play the match (Saturday) because I think it’s too much on our bodies.”

The tournament’s response highlights the increasing need for adaptability in professional sports as climate patterns shift. Players may need to adjust their strategies and equipment to cope with the fluctuating conditions.

Frequently Asked Questions

What triggers a break in play due to heat?

Under the Extreme Heat Policy (EHP), a 10-minute break is allowed between the second and third sets in women’s and junior singles, and after the third set in men’s singles when a four (4.0) is recorded on the AO HSS. A reading of five (5.0) could lead to a suspension of play.

Which courts at the Australian Open have roofs?

Rod Laver Arena, John Cain Arena, and Margaret Court Arena all have roofs that can be closed to provide shade and reduce temperatures.

When did the ATP introduce a heat rule?

The ATP only introduced a heat rule for 2026 after pressure from players following stifling heat and humidity at events like the Shanghai Masters last year.
