Phnom Penh
Cambodia
Phnom Penh is projected to confront a range of climate hazards that pose considerable risks to its citizens and infrastructure. The city will experience extreme heat and dangerous heat extremes, adversely affecting public health and energy consumption. Frequent heavy precipitation events are anticipated, increasing the likelihood of flooding and infrastructure damage. Aggravating these challenges, prolonged drought conditions are expected, leading to water shortages and affecting agricultural resilience. Furthermore, the heightened risk of arbovirus transmission linked to climatic changes poses significant public health concerns. These vulnerabilities emphasize the urgent need for a deeper understanding of the potential impacts of climate change on the city's future.
Hazard Outlook
How will Phnom Penh's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Heavy Rainfall Days
With 11 days of heavy rainfall expected, Phnom Penh ranks among the highest of all cities for extreme precipitation events.
Elevation
At 13 m elevation, Phnom Penh faces high risk from coastal flooding and sea level rise.
Maximum Temperature
Phnom Penh's projected maximum temperature of 10.1°C is higher than most cities globally under a 3.0°C warming scenario.
Longest Heatwave
Phnom Penh may experience heatwaves lasting up to 4 days, near the median of other cities.
Maximum Rainfall
Phnom Penh's projected maximum rainfall of 10 mm is near the median of cities globally.
Exposure Summary
Adaptation Priorities
Phnom Penh faces high exposure to heavy rain, elevation and elevated exposure to max temp. These areas may warrant priority attention in adaptation planning.
