Sydney has just broken a record that has stood since 1868 - the overnight temperature stayed above 27C.
In December 1868, Sydney registered a minimum temperature of 26.3C, a record that had stood ever since. On Tuesday night, the minimum was 27.1C. It also makes it the second hottest night on record for any month of the year, a Bureau Of Meteorology spokesperson said.
Sydney is experiencing high temperatures, at day and night, and in December, that is surprisingly uncommon.
Tuesday saw a maximum temperature of 39C and on Wednesday, it was 37.5.
