Cold weather in Sydney is defined by the city’s temperate maritime climate. Winter (June–August) brings average maximums of 16–18°C along the coast and 13–15°C in the western suburbs. The cold snaps happen when a high-pressure system stalls over Tasmania, funnelling dry, cool westerlies across the city.
