Melbourne heatwave: another record broken MELBOURNE is continuing to break heat records, after sweltering through its hottest seven nights in a row. After a record nine consecutive daytime temperatures over 30C, sleep-deprived Melburnians have now endured another record, for the longest run of high minimum temperatures. Bureau of Meteorology senior forecaster Rod Dickson says the minimum temperature has hovered above 20C for seven consecutive days. The previous record of six consecutive nights above 20C occurred twice before - once in 2009 and once in 2008. "It has certainly been the warmest start to March on record," Mr Dickson said. But it will take more hot days to beat the warmest March ever, in 1940 where the average maximum temperature was 28.9C. "Currently our average for the first couple of weeks is 32.5C, so we're above the highest March average ever recorded but we've still got half a month to go," Mr Dickson said. A cool change has finally reached Melbourne, dropping temperatures to just over 23C at 9.30am (AEDT). Mr Dickson said the change won't hit the northeast of the state until later on Wednesday. Temperatures are forecast to remain below 30C for the next week.
