Sydney residents were greeted with the coldest start to July in two years on Saturday morning as temperatures dropped to 3 degrees in the city and plunged to zero degrees in Campbelltown.

But while many residents chose to bunker down indoors, the opposite was true for the city's ice skaters.

A handful of amateur and professional enthusiasts embraced the chilly weather by taking to Bondi's ice rink, which opened on Friday as part of the Bondi Winter Magic festival.

While families lapped up the winter sun on the beachside ice rink throughout the afternoon, meteorologists warned that the mercury would sink yet again to single digits on Saturday night.

"Sunday morning will be as cold as it was this [Saturday] morning," Kim Westacott, a meteorologist with Weatherzone said.

"At the moment, it's looking like it will be 6 degrees in the city tomorrow morning, but that could still drop overnight."

A high-pressure system swept across the city on Saturday morning, bringing clear skies and still winds, the perfect recipe for a shivery start to the weekend.

Residents from Cabramatta to Collaroy faced a bitterly cold Friday night, but Campbelltown was the hardest hit, with temperatures dropping to zero.

Sunday is set to round off the coldest weekend of the year so far, with temperatures set to hover around 2 degrees in Penrith, and reach zero degrees in Campbelltown for the second night in a row.

Richmond will be the coldest part of the greater Sydney region over the next two days, with a minimum of -1 degrees on Sunday and 2 degrees on Monday.

However the cold weather will be welcome news to those hoping to get down to Bondi's ice rink to kick off the school holidays next week.

The beachside suburb can expect a minimum of 10 degrees on Monday, while light winds and blue skies should persist across Sydney for the remainder of the weekend.
