About Gillen's Climate Risk Profile

Gillen, located in Alice Springs, Northern Territory, is characterized by its arid climate and proximity to the Todd River. The primary climate-related risks for Gillen include flooding from intense rainfall events and extreme heat during the summer months.

The risk of flooding is primarily associated with the Todd River, which, while usually dry, can experience significant flows during periods of heavy rainfall. Urban development in the area may also contribute to increased runoff, exacerbating flood risk in certain locations.

Extreme heat is a significant concern for Gillen, with average maximum temperatures in January often exceeding 35°C. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.

While the risk of bushfire is relatively low compared to other regions of Australia, surrounding areas with more substantial vegetation could pose a threat during the dry season. Gillen is not exposed to coastal risks.
