All About Sydney Climate
Warm sultry summer days are frequently interrupted by short, sharp seasonal storms, which can add to the humidity. Summer temperatures generally range between 17 and 25 degrees Celsius, and afternoon and evening thunderstorms are common.
Winters tend to be sunny and warm, with temperatures between 8 and 17 degrees, with cooler temperatures in the evening. Autumn and spring have the mildest weather but it may be worth carrying a collapsible umbrella during those times.
