After a short reprieve on Sunday and Monday, Sydney will return to hot conditions on Tuesday with temperatures again expected to exceed 30 degrees.
After top temperatures of 26 degrees along the coast on Sunday and 27 degrees on Monday, the Bureau of Meteorology has forecast a top temperature of 37 degrees for the Sydney area on Tuesday.
Most of Sydney, including the city and east, is forecast to reach a top of 37 degrees while in Sydney's west, Penrith is set to reach 38 degrees.
A statewide Total Fire Ban has been declared due to forecast hot, dry, and windy conditions.
Winds will be from the north north-west in the morning and tending 25 to 40 km/h from the west north-west by the middle of the day.
There is a 30 per cent chance of rain.
Sydney won't feel relief from the heat until about midnight, when a cool change moving up the South Coast reaches the city, Bureau of Meteorology forecaster Rebecca Farr said.
The remainder of the working week is looking much milder with forecast temperatures of 26 degrees through until Friday.
