MELBOURNE, Australia (AP) — Melbourne is known for its wacky weather. The joke here is that you can experience four seasons in one day. But the heat wave that started Tuesday and is forecast to end on the weekend has brought what meteorologists are estimating as the longest stretch of weather this hot since 1908.

That's been bad news for the tennis players at the Australian Open, where Thursday was the hottest day so far.

There were the unlucky morning starters, like Maria Sharapova who played in 43 degree C (109 F) heat and cooled off at changeovers with ice vests on their bodies and ice collars around their necks. Some called trainers to complain of head spins, blurred vision and cramping from dehydration.

"I never actually experienced the heat today," said Federer, who advanced easily to the third round.

THE CONTROVERSY: The heat and the tournament's delayed decision to halt play sparked debate about whether it was dangerous to have allowed matches since Tuesday when the heat wave started.
