Bernard Tomic's Australian Open preparations could begin in searing 43 degree temperatures on Tuesday as Sydney International tournament directors consider allowing the men to play through the extreme heat that is forecast for Sydney's west.
Under the Women's Tennis Association's extreme weather condition rule, a 10-minute break is allowed between the second and third set once the Heat Stress Index reaches 30.1 degrees or the ground temperature hits 34 degrees, if it is requested by just one of the women in the match.
However, there is no such precaution for the men, leaving the safety of the male competitors in the hands of tournament officials.
The schedule for tomorrow's play won't be announced until this evening, but it's likely the all-Aussie first round showdown between Tomic and Marinko Matosevic will be set for the prime time of 5pm, potentially sheltering the pair from the full brunt of the ferocious conditions predicted for mid-afternoon.
Tournament directors will use a formula (Wet Bulb Globe Temperature), often used in the military, that takes into consideration the humidity, air temperature, court temperature, wind speed and radiation to deem whether conditions are safe enough for play at Sydney Olympic Park.
While the women are almost certain to benefit from an extended break between the second and third sets, the WTA has no rule that suspends play indefinitely.
Tournament officials are in discussion and are likely to wait until tomorrow before a decision is made, with the safety of not only the players, but staff and spectators, being considered.
Heat Stress Monitor readings are taken 30 minutes prior to match play, at noon and just before the last match, while Australian safety regulations are also being taken in consideration.
If play is suspended for more than 30 minutes, the players will be allowed a five-minute warm-up once they return to the court.
Former world No.1 Caroline Wozniacki seemed unphased about the scorching heat predicted in Sydney over the week when asked on Sunday after her first round victory against Urzsula Radwanska.
"Lovely, I can get a tan and my feet can burn a little bit," she said jokingly.
"But it's similar for everyone. You just need to focus on what you are doing out there and not focus on the heat.
"You know it can get really hot here in Australia sometimes and that's a part of the game. If you are fit physically, it makes it easier to cope with the heat."
Last year's Wimbledon runner-up, Agnieszka Radwanska, said she'll be taking steps to ensure she copes with the harsh weather.
"Well, for sure lots of drinking, and already today I think is good to be prepared for tomorrow," she said.
"But you never know. Sometimes you have a better day. Sometimes it's the worst day that you just can't really play your best tennis in these conditions.
"So you never know, especially when tomorrow will be very, very hot."
