The Melbourne major reached the highest level of five for the second time in four days on its scale designed to protect players, fans, and officials.
That means centre court, Rod Laver Arena, which hosts the day's four quarterfinals, closed its roof.
The opening quarterfinal of the day, between Aryna Sabalenka and Iva Jovic, took place in blazing sunshine.
The match, won by world No 1 Sabalenka, ended in temperatures of 38C.
Play on outdoor courts, which were to host junior boys' and girls' matches, were put on hold.
Temperatures reached 40C on Saturday, with matches on outside courts paused for about five hours.
