Montreal Heat Islands Map
How to use this tool
Explore the urban heat island intensity map to see which Montreal boroughs and neighbourhoods experience the highest surface temperatures. The visualization shows temperature differentials between green spaces and built-up areas. Filter by intensity level to identify the hottest zones where landscaping and tree planting have the greatest cooling impact.
Why it matters
Urban heat islands can raise temperatures by 5 to 10 degrees Celsius compared to surrounding green areas, creating serious health risks during Montreal's increasingly frequent heat waves. Strategic landscaping is one of the most effective ways to combat heat islands: a single mature tree can cool its surroundings by up to 2 degrees, and permeable surfaces with vegetation absorb less heat than asphalt or concrete. Homeowners in high-intensity heat island zones benefit most from shade tree planting, green roofs, and replacing impervious surfaces.
