During the first week of July an extensive low pressure trough formed off the northern NSW coast and then deepened rapidly.
The central pressure of this so called bomb cyclone fell from 1006mbs to 986mbs in just 18 hours.
Heavy to flooding rains lashed the south coast of NSW, with Ulladulla seeing a record 224mms fall in the 24 hours to 9am on 2 July.
There was only one other wetter day overall at Ulladulla, being 352.6mms on 30 October, 1959.
Narooma with 140mms recorded it's wettest July day in 115 years breaking a record which stood since 1934.
The rain from this bomb cyclone did extend to Melbourne with 13.6mms of rainfall keeping maximum temperatures down to 11 degrees and we enjoyed 17 degrees in North East Victoria.
I do remember a big bomb low which hit the Newcastle area on 8 June, 2007.
I did a survey of maximum temperatures around the nation some 10 days later and found that Australia's coldest ever day did occur on 20 June, 2007.
From August 2007 onwards we enjoyed warmer than normal conditions, then above average rainfall in November and December and then very hot conditions from the end of December to mid January 2008.
Most of the Kimberley region has had zero rainfall since 27 May and this has led to mean minimum temperatures for the first nine days being more than four degrees below the July normal at Broome, Derby and Fitzroy Crossing and the coldest in July since 2022 or in 2002, 1967 and 1896.
