How to stay cool in a heatwave
Sydney-siders share their tips for dealing with the record temperatures.
With 35 degrees tipped for Monday, the city has another shot at breaking a record that has stood since the summer of 1895-96.
Weather stations at Sydney Olympic Park, Camden, Richmond, Holsworthy and Canterbury all recorded temperatures surpassing 40 degrees on Sunday afternoon. Bankstown's 42.7 degrees was the city's hottest.

Joel Pippard, a meteorologist at Weatherzone, said the heat would most likely remain in the high 30s across the city throughout the afternoon with the maximum predicted temperature "possible throughout the day until about 6pm".
"A slight sea breeze is going to be switching on and off all day, so that maximum temperature should never come and stay," Mr Pippard said.
But the heat would most likely peak about 3pm, before starting to cool off after 6pm, Mr Pippard said.
A slight chance of rain and thunderstorms across the city and particularly out west is possible in the late afternoon, and is likely to hit "before any kind of cooling starts" in the early evening.
"The current record of nine days was made in 1896," Mr Pippard said.
"We've already equalled that record of nine days this summer."
Overnight, the temperature should drop to 25 degrees but will most likely remain in the high 20s until about midnight, Mr Pippard said.
The heat will continue on Monday with a top of 35 degrees predicted in the city and 41 in Penrith, although a "cooler breeze" should provide some relief throughout the day.
The temperatures will finally cool down with a strong southerly change late on Monday afternoon, Mr Pippard said.
The milder conditions will most likely continue on Tuesday and Wednesday with possible showers, before picking up again on Thursday, the Bureau of Meteorology forecast.
A return to uncomfortable conditions late in the week is set to be more pronounced in the west, with the temperature expected once again to climb into the 40s by Saturday.
