Montreal
Canada
Montreal is projected to face increasing climate hazards, particularly frequent heatwaves and heavy precipitation. The rise in heatwaves poses serious health risks for vulnerable populations and may lead to infrastructure stress. Simultaneously, the city will experience more intense rainfall, resulting in heightened flood risks and possible erosion that can overwhelm existing urban drainage systems. These projected changes are anticipated to worsen over time, making Montreal increasingly vulnerable to extreme weather events. Addressing these vulnerabilities is crucial to enhance the city's resilience against climate-induced challenges in the coming years.
Hazard Outlook
How will Montreal'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, Montreal ranks higher than most cities for extreme precipitation events.
Elevation
At 30 m elevation, Montreal faces elevated risk from coastal flooding and sea level rise.
Maximum Temperature
Montreal's projected maximum temperature of 8.9°C is near the median of cities globally under a 3.0°C warming scenario.
Maximum Rainfall
Montreal's projected maximum rainfall of 11 mm is near the median of cities globally.
Longest Heatwave
Montreal may experience heatwaves lasting up to 3 days, lower than most other cities.
