Haikou
China
Haikou is projected to face a future characterized by severe climate hazards, including frequent heatwaves, which pose significant health risks. Alongside this, heavy rainfall events are expected to increase in severity, leading to potential flooding and infrastructure damage. Prolonged drought conditions will also challenge the water supply and agricultural output. Furthermore, the city will experience a heightened risk of arbovirus transmission, driven by changing climatic conditions, alongside an elevated malaria risk, placing additional burdens on public health. These vulnerabilities highlight the urgent need for comprehensive climate risk assessments and proactive adaptation strategies, as Haikou navigates these escalating threats to its environment and community health.
Hazard Outlook
How will Haikou's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Maximum Rainfall
Haikou's projected maximum rainfall of 15 mm is among the highest of all cities globally.
Elevation
At 19 m elevation, Haikou faces high risk from coastal flooding and sea level rise.
Longest Heatwave
Haikou may experience heatwaves lasting up to 5 days, higher than most other cities.
Maximum Temperature
Haikou's projected maximum temperature of 8.6°C is near the median of cities globally under a 3.0°C warming scenario.
Heavy Rainfall Days
With 9 days of heavy rainfall expected, Haikou ranks lower than most cities for extreme precipitation events.
Exposure Summary
Adaptation Priorities
Haikou faces high exposure to max rain, elevation and elevated exposure to heatwave. These areas may warrant priority attention in adaptation planning.
