With the temperature soaring to 110 degrees Fahrenheit (43 Celsius), the mixed doubles semifinals have been played under a closed roof at Rod Laver Arena.
The Australian Open's “heat stress reading” reached a maximum level of 5.
In addition to shutting the main stadium's roof, tournament officials postponed the start of play for junior and wheelchair competition because those were scheduled for smaller courts that do not have a retractable roof.
A brief rain shower in the afternoon helped lower the temperature to about 100 degrees (40 Celsius).
