The Wet Bulb Globe Temperature (WBGT) is monitored daily, every half hour from 10:00am. The Extreme Weather Policy was immediately activated at the Tokyo 2020 Olympic Tennis Event on Saturday 24 July, the first day of matches, as soon as the temperature reached the WBGT threshold of 30.1°C. Play was modified to provide players with a 10-minute break between the 2nd and 3rd set. The modification of play provision has been continued today and will be implemented for all matches on Day 2, Sunday 25 July, while the WBGT reading remains above 30.1°C.
In addition, change of ends and set breaks are extended by an extra 30 seconds to enable players more time.
If the temperatures increase, the WBGT temperature threshold for a possible Suspension of Play will be determined by an internal advisory group. The group includes the Referee, Tournament Medical Services, and operational representatives. In planning for a possible Suspension of Play, the group will convene once the WBGT threshold reaches 30.1°C to consider the weather forecast for the current day plus the prior 1-2 days and next 1-2 days, as well as expert medical advice and all variables that determine player safety.
