Source Weatherzone Sun 20 Jul 2025

Extremely cold temperatures were observed in Sydney and across Greater Western Sydney this morning, with many locations shivering through their coldest morning in years. Penrith experienced its coldest morning in 4 years as the mercury dropped to -0.3°C at 6:45am. Temperatures were even colder at Campbelltown, Richmond and Camden with minimum temperatures of -0.5°C, -1.3°C and -2.1°C respectively. These subzero temperatures resulted in widespread frost across Greater Western Sydney this morning. Sydney Olympic Park was extremely cold as well with a minimum temperature of 2.8°C, its coldest temperature in 2 years. These cold temperatures were facilitated by clear skies and very light winds which promoted radiational cooling through the night. These conditions also allowed areas of fog to form. Notably, the visibility in Richmond dropped as low as 100m at times overnight. Although temperatures are not expected to be quite as cold during the coming week, morning temperatures will be chilly on Thursday and Friday, particularly in western suburbs.
