What the evidence shows
Three ways to read the citywide picture before you open the layers yourself.
- Where Zagreb runs hottestDonji Grad, Trešnjevka – sjever, and Trnje lead summer surface heat, with dense inner-city blocks consistently warmer than greener edges.
- Who is most exposedHeat risk is not only where temperatures peak, but where elderly residents, density, and limited cooling overlap in the same neighbourhoods.
- Where to act firstPriority neighbourhoods combine extreme heat, high density, and above-average elderly share. This provides a concrete starting list for trees, shade, and cool surfaces.
