Day 4 of the Australian Open has been really HOT. So much so that several matches having to be suspended not only in the afternoon, but also at night due to the lightning. The roof tops at Rod Laver and Hisense Arena were also closed as a safety precaution. Temperatures have reached a top of 44 degree celcius since Day 1, and is showing no signs of cooling down for the next few days. Looks like the best seats in the house for the moment would be at the comfort of your own home.
