Weather of Sydney Australia is characterized by warm summersand mild winters with sufficient rainfall all the year round.
The climate of Sydney Australia is oceanic. Sydney Australia experiences a moderate climate due to its proximity to the ocean. Extreme temperatures are recorded in the inland western suburbs.

Though the city does not suffer from cyclones or earthquakes, the El Niño Southern Oscillation plays a crucial role in determining the weather pattern of Sydney Australia . Drought, bushfire, storms and flooding accompanied by the opposite phases of the oscillation characterize the climate of Sydney Australia . Bushfires have a tendency to occur during the spring and summer. Sydney is also prone to hail storms and wind storms. The city of Sydney is also prone to flash flooding resulting from huge amounts of rain caused by East Coast Lows.
Recent research conducted by an atmospheric scientist of Macquarie University suggests that land clearing in western Sydney has influenced major changes in the climate of Sydney city.
