If you are unlucky enough to be up at sunrise, temperatures in the city are expected to drop to about 5 degrees, while Sydney’s west can expect areas of frost and fog.

Thanks to some overnight cloud, however, early mornings for the remainder of the week are looking to be more forgiving, with the minimum temperature almost doubling to 9 degrees on Tuesday.

Closer to the weekend, temperatures are expected to remain steady but showers are more likely. There is an 80 per cent chance of rain on Friday.

“We could see more significant rainfall after next weekend and that may affect the temperatures,” Mr Cronje said.

Earlier this month, Sydney reached a top of 25.2 degrees, almost matching the July record for the highest temperature, 25.9 degrees, which was set in 1990.

But as we move into the second half of winter, Mr Cronje said the temperatures for the month have been sitting right around the expected average for July, with cold nights making up for the warm winter days.

“In general, we have had above average daytime temperatures almost every day so far in July, but overnight temperatures have been a bit more up and down,” he said.

“We’ve seen some very cold nights, one even below 5 degrees.”
