How hot was it?
It was so hot, you could fry an egg on the tennis court at the Australian Open tennis tournament in Melbourne.
And in fact, someone did.
Tennis player Novak Djokovic sent around a picture of an actual egg on a tennis court, frying in the heat. The picture quickly went viral, meaning that many people saw it.
If it was that hot for an egg, imagine people playing top-level tennis in that heat.
Some of the players took baths in ice water to offset the effects of the heat, as the temperature climbed to 43-degrees Celsius.
Canadian tennis player Eugenie Bouchard is emerging as a rising star, advancing to the fourth round of the tournament.
She is the first Canadian in 22 years to reach the quarter-finals in a major tennis tournament.
