We're in for a cold snap this weekend, with the Bureau of Meteorology predicting an "early blast of winter" is on the way.
While Wednesday and Thursday's temperatures will remain in the mid-20s, the city's unseasonably warm weather will be ushered out by a cold front moving across the state.
"We have a high pressure ridge over us at the moment and we've had a few cold fronts moving over the southern ocean rather than pushing up onto the continent which is why we're seeing these warmer temperatures," BOM's Senior Forecaster Rebecca Kamitakahara told The Daily Telegraph.
"This will cause the temperature to drop quite dramatically on Friday for all of NSW and Sydney.
"Over parts of the ranges and western slopes it's going to be quite cold with this front."
Which means we're looking at highs of 18C on Friday and Saturday with, Ms Kamitakahara said, an increase in showers to boot.
We've been waiting a while to say it but it looks like it's time.
Winter is coming.
