The urban heat island effect is an extensively documented climate phenomenon and is prevalent in many Australian cities. Concrete buildings and asphalt roads create heat islands that can be significantly hotter than temperatures in the surrounding suburban and rural areas. Because the number of extreme heat days is predicted to increase significantly over the next few decades, and the urban heat island effect has been shown to be exacerbated by climate change, the City of Adelaide is working to understand and reduce heat islands.
A Heat Mapping Tool is publicly available which assesses how all suburbs are affected on hot days and nights. The City of Adelaide is using this data to inform its planning and design, for example in tree planting and choice of materials in public spaces like playgrounds, parks and pavements. Residents and businesses can consult the tool to understand how heat exposed their property is.
You will find a graph in the image gallery that depicts the average land surface temperature for a range of different surfaces measured across the Heat Mapping study area. Bitumen is one of the consistently hot urban surfaces both day and night, covers a large part of our city, and is directly controlled by the City of Adelaide.
Consultation has concluded.
