According to the Weather Bureau, it got to 41 degrees in Melbourne today.
The Australian Open has an "Extreme Heat" policy whereby games stop when the weather goes over 35 degrees (which can effectively be 50 degrees on the court).
The thermometer in my home office reached 46.3 degrees today. I suspect this probably wasn't good for computers - which were merrily adding to the heat. But I wasn't playing tennis, so I don't suppose I would have wilted quite as much as the tennis players.
The thermometer also shows that it got to 43.7 degrees on my balcony: which is probably accurate since there would have been sun on the outside sensor during the morning, whilst the whimpish Weather Bureau protect their thermometers by always keeping them in the shade.
By the way, a really great graph of the weather in Melbourne as it changes over a day/week/month can be found here. The author of this site picks up data from the Weather Bureau and displays it graphically. There's an interesting real time comparison of weather in Melbourne and Sydney here and comparing Melbourne with Canadian cities here.
For the record (since the graph will change with time), here's what today looked like:
