Australian Open tennis encounters extreme heat
"Australian Open organizers instituted their extreme heat policy as temperatures soared at Melbourne Park on Tuesday. It prompted the suspension of play on outer courts and the closure of roofs on the main showcourts. The protocol, introduced in 2019, was developed to minimize the risk of heat-related illness and provide consistency for all players. It considers air temperature, radiant heat, wind speed humidity to assess playing conditions, and sets thresholds for cooling interventions."
"The tournament's "Heat Stress " reached the highest threshold of 5.0 on Tuesday afternoon with thetemperature breaking through the 40 degrees Celsius, or 104 Fahrenheit, mark by 2 p.m. The threshold was reached soon after world number one Aryna Sabalenka completed her 6-3, 6-0 win over teenager Iva Jovic. "At the end the match, it was really hot out there," Sabalenka told reporters."
Extreme heat forced suspension of play on outer courts and closure of roofs on main showcourts at Melbourne Park. The extreme heat policy introduced in 2019 aims to minimize heat-related illness and provide consistent treatment for all players. The protocol evaluates air temperature, radiant heat, wind speed and humidity and uses thresholds to trigger cooling measures and extra breaks. The tournament referee can suspend outdoor play or order additional cooling breaks when thresholds are reached. Heat Stress reached the highest 5.0 threshold as temperatures exceeded 40°C. Spectators were urged to wear hats, use sunscreen and drink water. Southeastern Australia faced forecasts up to 45°C, peaking midweek before easing.
