About Croydon's Climate Risk Profile

Croydon, located in the Inner West of Sydney, is a primarily residential suburb with a mix of Federation and Californian Bungalow style homes. The suburb's climate risks are primarily associated with flooding and heatwaves, both of which are expected to worsen with climate change.

Flooding is a concern due to the suburb's proximity to local waterways and drainage systems that can be overwhelmed during heavy rainfall events. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flooding.

Heatwaves are another significant risk, particularly for vulnerable populations. The urban environment of Croydon contributes to the urban heat island effect, exacerbating the impact of rising temperatures. Increased heatwave frequency and intensity could lead to heat stress and other health problems.

Bushfire risk is relatively low due to the suburb's urban setting and distance from large bushland areas. However, it's important to maintain vegetation and be aware of potential fire hazards, especially during dry periods.

Coastal risks are minimal as Croydon is located inland and is not directly exposed to sea level rise or coastal erosion.
