Horsham faces a moderate risk of flooding due to its proximity to the Wimmera River and other waterways. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
Bushfire
Horsham has a relatively low bushfire risk compared to other parts of Victoria, but is still susceptible due to surrounding grasslands and bushland. Drier conditions and higher temperatures could increase the risk of bushfires.
Heat
