Sydney will wake up to its coldest morning in four years today, reaching a low of 5.5 degrees.
It's a chilly start to the day after a surprisingly warm week, which hosted the warmest three consecutive days in any July for the city, topped off with a balmy 25 degrees on Thursday.
Brett Dutschke, senior meteorologist with Weatherzone, said gloves and scarves would be a must for some this morning.
"It's the coldest morning in four years but it's also the coldest August morning in 6 years," he said.
"There is also still a bit of a gentle breeze, which will make it feel as cold as the temperature suggests."
Sunday is likely to reach a maximum of 17 degrees and should become reasonably comfortable as winds gradually drop off during the day.
Heading into the week the colder mornings are set to continue through until at least Thursday.
"The first half of August is going to be quite cool, as we will still have a few chilly nights and mornings and we are not going to get many days where we hit 20 degrees," Mr Dutschke said.
However he said the latter half of the month would see temperatures warm up noticably.
Snowfall in the Blue Mountains kicked off the chilly start to the month with heavy snow around Mount Victoria and Medlow Bath.
Canberra is experiencing an even colder start to Sunday, reaching a low of -3.2 at 8am.
