Sydney and Brisbane both broke their summer heat records, making it feel as if locals moved hundreds of kilometres north for the summer.
A warm week has come to an end - and with it, the high temperatures that dominated our weather over the past seven days.
Sydney just endured its hottest summer in more than 150 years, setting a number of new records relating to heat.
The hottest season since record-keeping commenced 159 years ago included an unprecedented 26 days at or above 30 degrees in the city and 11 days over 40 degrees in Richmond.
The chance of El Nino forming during 2017 has recently increased according to the latest El Nino Southern Oscillation (ENSO) wrap-up released by the Bureau of Meteorology on the final day of summer.
So, what are the chances of El Nino forming this year? And what would this mean for weather in Australia?
Parts of Australia's eastern seaboard could receive more than a month's worth of rain in the next week, raising the risk of flooding during the opening days of autumn.
The highly populated stretch of coastline between southeast Queensland and eastern Victoria will be hampered by days of rainfall from now until the weekend.
If you wanted to stay a bit warmer today in eastern Australia then a dip in the ocean is probably your best bet, despite the rain.
Ocean surface temperatures along the east coast are currently warmer than the 18 degrees in Sydney city, around 20 degrees close to the coast and above 24 degrees further offshore.
Although autumn is on the way, the Bureau of Meteorology has warned the hot weather is likely to continue, with warmer than average temperatures forecast for most of southern and eastern Australia.
Perth, and much of Western Australia's southwest are about to experience their final scorcher of the summer.
