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.
