Scorching heat halted outdoor matches and sent fans scurrying for shade at the Australian Open on Tuesday as players were given an early test of their endurance on a sweltering day two at Melbourne Park.
Organizers invoked their Extreme Heat Policy about three hours into the day session as temperatures nudged 36 degrees Celsius (97F) and searing gusts of wind blew through the venue.
The tournament’s Heat Stress Scale, which measures radiant heat, humidity, and air temperature in the shade, crossed its highest threshold of 5.0, halting 10 outdoor matches at the Grand Slam.
Play continued under the roofs of the main show courts, however, with former world number one Andy Murray sweating it out against Italian Matteo Berrettini at Rod Laver Arena.
Organizers said play on outdoor courts would not resume before 5 p.m. local time (0600 GMT).
The suspension of play was not welcomed by all players, with local man Jordan Thompson blowing his cool when his match on Court Three was halted when trailing American J.J. Wolf 6-3 1-3.
“When does that ever happen?” world number 88 Thompson barked at the chair umpire.
“I’ve been here when it’s like 45 degrees.”
The temperature was already nudging 30 degrees Celsius when matches started in the morning, and Canada’s Leylah Fernandez was glad to see off French veteran Alize Cornet in straight sets in the first match on Court 3.
“I think I did well to manage my emotions, and then especially manage the heat, try not to get too hot-headed,” Fernandez told reporters.
“So I was very happy with that.”
Extreme heat is a feature of the Australian Open, held in mid-summer in the country, with play occasionally suspended and leaving organizers with scheduling headaches.
Tennis Australia tweaked its extreme heat policy at the end of 2018 after a slew of players complained of health and safety risks under the previous system.
