In some previous post, I described the extreme weather policy informally based on my
understanding. Now, it is time to describe it in official wording. The following is taken
from AO website.
Extreme heat policy
In the event of extreme heat, the Referee has the right to order a rest period and/or suspend play at any time as per the following policy:
•The Australian Open Extreme Heat Policy will be applied at the Referee’s discretion and may be altered at any time;
•At the Referee’s discretion, the Tournament Referee may suspend the commencement of any further matches on outside courts;
•Any matches currently in progress will continue until the end of the current set. At the completion of the set, play will be suspended;
•Where play in any match commences outdoors (or with a roof open), the match will continue until the completion of the set. At the end of the set a decision will be made by the Referee to close to the roof for the remainder of the match and the following matches, where the EHP is still in effect (On Rod Laver Arena and Hisense Arena);
•A roof will only be closed because of extreme heat if a decision has been made by the Referee to suspend the completion or commencement of matches on the outdoor courts; When the EHP has been implemented, the Tournament Referee will suspend the calling of any further matches on outside courts;
•Supplement: In the Women’s Singles, to allow a 10 minute break between the 2nd and 3rd sets when a WBGT 30.1 reading has been recorded prior to the calling of the match by Tournament Control. Readings are continually made throughout the day.
•For Junior Singles, to allow a 10 minute break and Wheelchair Singles to allow a 15 minute break between the 2nd and 3rd sets, this will be applied at the Referee’s discretion at a pre- determined threshold, prior to the calling of the match by Tournament Control. Readings are continually made throughout the day.
•The break will not apply between the second and third sets if play had previously been suspended after the first set due to EHP.
•During the suspension of play, the Referee will review the conditions and make a decision as to whether the EHP is still in force. A player will be given at least 30 minutes notice prior to the resumption of play. Announcements will be made via the public address system.
