Helsinki
Finland
Helsinki is projected to confront substantial climate hazards due to frequent heavy precipitation. As climate change influences weather patterns, the city will experience intensified rainfall, leading to elevated flood risks. This increase in precipitation threatens urban infrastructure and water management systems, overwhelming existing drainage capacities. Consequently, the city faces heightened vulnerabilities related to water-related issues, impacting public safety and natural ecosystems. The anticipated rainfall intensification suggests that Helsinki must prepare for significant challenges in managing stormwater and maintaining urban resilience in the face of these evolving climate conditions. The projected future impacts of heavy precipitation underscore the urgent need for comprehensive assessments of climate-related risks in the area to inform effective planning and response strategies.
Hazard Outlook
How will Helsinki's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Elevation
At 0 m elevation, Helsinki faces very high risk from coastal flooding and sea level rise.
Heavy Rainfall Days
With 11 days of heavy rainfall expected, Helsinki ranks among the highest of all cities for extreme precipitation events.
Longest Heatwave
Helsinki may experience heatwaves lasting up to 6 days, higher than most other cities.
Maximum Temperature
Helsinki's projected maximum temperature of 7.3°C is lower than most cities globally under a 3.0°C warming scenario.
Maximum Rainfall
Helsinki's projected maximum rainfall of 6 mm is lower than most cities globally.
Exposure Summary
Adaptation Priorities
Helsinki faces high exposure to elevation, heavy rain and elevated exposure to heatwave. These areas may warrant priority attention in adaptation planning.
