Sydney - Recent December Temperatures and Rainfall

The numbers here describe what the December weather in Sydney, New South Wales Australia was like for every year since 2010. A series of tables gives December data by year for temperature and precipitation.

They begin with average maximum and minimum temperatures in degrees Fahrenheit and Celsius. That's followed by how many hot days occurred each December. Then there's information on how much rain actually landed this month during recent years, as well as how often Sydney had wet weather.

The climate data up until 2019 come from weather measurements made at Sydney's Observatory Hill Park. Since then the weather was recorded at Sydney Airport.
