Fears Sydney would experience its coldest day in two years on Sunday morning have abated thanks to a change in air temperatures.

Instead, Sydneysiders can look forward to a sunny, albeit slightly below average, start of the week with a minimum of 7 degrees and a top of 17.

Duty forecaster Andrew Haigh from the Bureau of Meteorology said it would be a cold start to the day in the morning, with some frost in the west.

"The west will experience a minimum of zero to 2 degrees, which is below the July average," Mr Haigh said.
