Thursday night was the warmest July night in four years, with the city only cooling to 15 degrees. Under the sunshine that preceded the rain this morning, the city saw it’s fifth day above 20 degrees, which has not occurred in July for 85 years.

It will be another mostly sunny day today but temperatures will start to cool down as a cold front crosses during the day.

It should reach 18 degrees Saturday, with the mercury sinking quickly in the evening, before an even cooler day on Sunday with a high of of 17 degrees. On Sunday particularly, the wind will create a chill, making it feel 2-3 degrees colder than what it actually is.

This sudden change of temperatures will have Sydney residents rushing for their slippers and jumpers.

Looking further ahead, temperatures will be pretty much normal for July from Monday throughout the week, with chilly mornings and maximums in the mid-to-high teens.
