About Penrith's Climate Risk Profile

Penrith, located in western Sydney, is susceptible to a range of climate-related hazards. The most significant risk is flooding, due to the suburb's location on the floodplain of the Nepean River. Heavy rainfall events can cause the river to overflow, inundating homes and businesses. Climate change is projected to increase the frequency and intensity of these events, leading to more severe flooding in the future.

Bushfire risk is also a concern in Penrith, particularly in areas bordering bushland. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Climate change is expected to lengthen the bushfire season and increase the intensity of fires, posing a greater threat to life and property.

Heatwaves are another significant hazard in Penrith, with temperatures often exceeding 40 degrees Celsius during summer. These extreme heat events can cause heatstroke, dehydration, and other health problems, particularly for vulnerable populations. Climate change is projected to increase the frequency and intensity of heatwaves, making this risk even more pressing.

While Penrith is not directly exposed to coastal hazards, the impacts of climate change on other regions can have flow-on effects. For example, disruptions to supply chains or displacement of populations due to coastal erosion could affect Penrith's economy and infrastructure.

Addressing these climate risks will require a combination of adaptation and mitigation measures. Adaptation strategies include improving flood defenses, managing bushfire risk, and implementing heatwave early warning systems. Mitigation efforts involve reducing greenhouse gas emissions to slow the pace of climate change.
