Explained: Why the Australian Open is starting early on Saturday

Extreme heat is set to dominate the Australian Open on Saturday, with temperatures expected to touch 40C and organisers forced into schedule changes while issuing safety warnings for fans.

Match play on Melbourne’s main show courts will begin earlier than usual at 10:30 am, instead of the standard 11:00 or 11:30 am start. Action on the outer courts will get underway from 10:00 am as officials look to make use of cooler morning conditions.



Spectators attending the grounds have been advised to take precautions against the intense sun and heat.

Tournament director Craig Tiley said the decision was taken to reduce exposure during the hottest part of the day. He explained that conditions are expected to be far more comfortable in the morning, with temperatures in the mid-20s, allowing organisers to maximise play before the heat peaks.

Saturday’s schedule includes appearances from Novak Djokovic, men’s champion Jannik Sinner and women’s title-holder Madison Keys.

Forecasts suggest the temperature will climb sharply through the afternoon before easing back to more typical January levels on Sunday. However, another severe spike is expected on Tuesday, when temperatures could soar to 43C.

Daniil Medvedev, a three-time finalist at the Australian Open, is not playing on Saturday but admitted the conditions could affect his preparations ahead of the last 16. He said practice plans may need adjusting if the heat becomes overwhelming, adding that indoor sessions remain an option, though he prefers to train outdoors.

Medvedev also acknowledged the challenge facing players scheduled to compete, saying it will be fascinating to see how they manage in such extreme conditions and hoping there are no serious health issues.

Under Australian Open regulations, the tournament referee has the authority to suspend play or introduce cooling breaks when conditions become too dangerous. On courts with retractable roofs, including Rod Laver Arena, play can continue with the roof closed if required.
