How Much Has Temperature Increased in Sydney?
Discover how much Sydney's temperature has increased since 1910, recent warming trends, longer summers, and rising heat patterns explained clearly.
Sydney’s recent warming trend corresponds to broader temperature patterns experienced by the rest of Australia. Average temperatures have increased by approximately 1.4 to 1.5 degrees Celsius since 1910, with New South Wales (which includes Sydney) experiencing a similar increase of approximately 1.4 Degrees Celsius.
The majority of global warming for both cities has occurred since 1950 and has continued to get progressively warmer every ten years (i.e., there has always been at least one decade that was warmer than the one that preceded it). As such, the climate in present-day Sydney is much warmer than previous generations experienced on both an occasional and consistent basis.
Recent Changes (Last 10–30 Years)
Over the last several decades, the focus has shifted from large jumps to a steady increase in temperatures. Some examples include:
- Approximately 0.2 degrees Celsius increase between 2010 and 2025 (Sydney);
- An increase in the number of days that exceed 35 to 40 degrees Celsius;
- An increase in nighttime temperatures (which means less relief from heat);
More importantly, the summer months are becoming longer and more intense. Research indicates that the summer season in Sydney has increased from about 80 days in 1990, to approximately 130 days now, indicating that there has been a significant change in the way people experience seasonal variations in temperature.
What’s Changing Beyond Just Temperature
The way heat feels is one factor that makes a difference.
- More hot days & Longer periods of heat
- There will be fewer nights of cold in and around the cities
- There will be an increase in the urban heat island effect within the western suburbs
- Higher demand for energy to cool our buildings
So while the temperature is increasing, it is also felt more through longer-lasting heat and a shorter time to recover.

Final Words
Sydney has not experienced an extreme jump in temperature; instead, the average temperature has increased gradually.
Further, the temperature patterns have changed, so now there are longer summer periods, more extreme heat, and fewer cool periods. Therefore, today, you can say that Sydney is not only hotter than before, but it is also becoming a hotter place to live throughout the entire year!
FAQs
1. How much does Sydney warm overall?
In Sydney, there has been approximately a 1.4°-1.5°C increase in average temperature as of 1910 (which is consistent with the national average).
2. Has the increase in temperatures increased dramatically over time?
Yes. The majority of this warming occurred between 1950 and 1975, while there has been an increase in extreme heat events during recent years.
3. Are summers becoming hotter or longer?
They are both. The summer season’s average temperature has increased substantially, and the summer season is lasting a longer duration.
4. Will Sydney become hotter over time?
Yes, based on projections, average summer temperatures will continue to rise, and the number of hot days in the future will increase as well.
