The block matters more than the district
Heat islands are local: a dense, treeless street can be several degrees hotter than the park edge three blocks away. Check the map above for the exact address before a viewing.

Where does Linz stay coolest?
Linz stays coolest in Altenberg bei Linz, Gramastetten and St. Florian.
Summer heat is a location question. wohnwahn evaluated the heat load (modelled from the official imperviousness data) for every inhabited 250 m cell in Linz, and the gap between districts is wide: Altenberg bei Linz sits at a median heat load of 41/100, Innere Stadt at 78/100.
And because a district is not an address: the map below shows the heat island, and the cool courtyard three blocks away.

Method: heat load modelled from the official Copernicus imperviousness layer (EEA, CC BY), one value per inhabited 250 m cell, clipped to the real district boundary. Honest caveat: even hot districts have cool courtyards and park edges; the map above shows the exact spot.

The heat map of Linz and surroundings
Green means cool, red means heat island. Every square is an inhabited 250 m cell with its heat load, modelled from the official Copernicus imperviousness layer (there is no official heat map here).
Only inhabited cells are coloured, city and surroundings alike (the model covers both). Tap the map: the heat load for that exact spot.
How to find a flat that stays cool
Trees and water are real cooling
Street trees and nearby water measurably cool their surroundings. Every wohnwahn listing shows the trees around the address and the water proximity of the location.
Top floor, west windows, no shade?
The flat itself decides the rest: an attic flat with west-facing windows heats up differently than a shaded courtyard flat. The sun check shows sun hours and shading for any address, per floor.
Think about the evening
Hot locations stay warm at night, and nights are when heat hurts sleep. Cool spots with green buffers cool down faster after sunset. The heat load value reflects exactly that.
Frequently asked questions
Where is it coolest in and around Linz?
By the heat load per residential spot it is Altenberg bei Linz: median heat value 41/100, ahead of Gramastetten and St. Florian. Source: heat load modelled from the official Copernicus imperviousness layer, evaluated per 250 m cell.
How big is the difference between districts and municipalities really?
Large. Altenberg bei Linz sits at a median heat load of 41/100, Innere Stadt at 78/100. Within a district the spread is just as real, which is why the map shows every single 250 m cell.
What is “heat load” and where does it come from?
There is no official heat map for Linz, so wohnwahn models the heat load from the official Copernicus imperviousness layer (EEA, 10 m): sealed ground is what heats up. The model is calibrated on 818 official Vienna cells and applied per inhabited 250 m cell and translates it into the words you see here (very low to very high).
Do trees and water really help?
Yes, measurably: vegetation and water cool their local surroundings through shade and evaporation. That’s why every listing on wohnwahn shows the street trees around the address (City of Linz tree register) and the water proximity of the location.
What about climate change: will it stay cool?
Heat is rising city-wide, so the honest question is which locations have a buffer. Cool spots with green and water cushion hot summers better than dense, sealed blocks. The heat map above is the best available official basis for that decision, and we refresh our evaluation monthly (as of October 2026).
