Temperature Controls in the city of Canberra in Australia

This is my first post in this blog and my second assignment. Today I am going to talk about what factors that controls the temperature in Australia. Like why is the temperatures in this city what they are, and the different processes.

Canberra, the capital of Australia is located in New South Wales, southeast in the country. Actually Canberra is an own state, called: “Australian Capital Territory”, just like Washington D.C in the US. The capital is located on latitude 35, 307 °S and longitude 149, 12°E.

The warmest month in this city is January with an average monthly temperature of 21, 05 °C (69, 8 °F). The coldest month is July with an average monthly temperature of 5, 75 °C (41 °F). The seasons in Canberra is reversed compared to Honolulu, when we have summer they have winter. Based on the information above the annual range of temperature for this city is 15, 3 °C (59 °F)

Websites where I found this information:


            The geographic position is one of the factors that control the temperature in this city. I have a map below showing the normal wind currents in Australia along with Canberra marked as a red dot.

The city is known for very cold winter temperatures and warm summer temperatures. That can be described from the wind currents and the geographic position. Canberra is located on the east coast with the winds normally coming from the west, towards the east. That means the city is located on the “Leeward” side of the continent. And the leeward location normally has warm summers and cold winter, the opposite of the windward position. You can compare this to the Island of O’ahu, where the leeward position is on the west coast, where the temperatures are hotter in summer and colder in winter, compared to the east coast. Without this effect the summer temperature in Canberra would be colder and winter temperature milder.

            There are many factors that control the temperature in Canberra, but there is one factor that we have learned in class that I don’t think has any relation to this city, and that is ocean currents. Although this city is located on the east coast, it is still located far from the sea, approximately 150 km inland. I don’t think the ocean currents affect the temperature in Canberra.

            The global change trend has led to a warmer earth, and by increasing the Earth’s average temperature a little bit can lead to major consequences. I think Canberra will be influenced in a lot of ways if the temperatures keep increasing. A warmer climate will also warm the ocean, and that will make the water molecules bigger and the water level eventually will increase. An increased water level will definitely affect Canberra, and the lands around, because I know there is a lot of agriculture in Australia.  There are also other factors that can happen. Maybe the differential heating between land and ocean will change, and that will definitely have some affect.
