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 Vienna stay coolest?
Vienna stays coolest in Döbling, Donaustadt and Hernals.
Summer heat is a location question. wohnwahn evaluated the official urban climate analysis for every inhabited 250 m cell in Vienna: 26% of residential spots have low heat load, and the gap between districts is wide: in Döbling 45% of spots stay cool, in Josefstadt only 0%.
And because a district is not an address: the map below shows the heat island, and the cool courtyard three blocks away.

The heat map of Vienna
Green means cool, red means heat island. Every square is an inhabited 250 m cell with its official heat load (urban climate analysis, City of Vienna).
Only inhabited cells are coloured. The official analysis covers Vienna; for the towns around the city there is no comparable map, so we honestly show none. Tap the map: the heat load for that exact spot.
Cool, yet in the middle of it
Cool usually means the green edge of town. These districts prove you can have both: share of residential cells with low heat load AND within 25 minutes of Stephansplatz by transit (matched per cell).
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
Which is Vienna’s coolest district?
By the share of cool residential spots it is Döbling (1190): 45% of inhabited cells have low heat load (median heat value 49/100), ahead of Donaustadt and Hernals. Source: official urban climate analysis, evaluated per 250 m cell.
How big is the difference between districts really?
Large. In Döbling, 45% of residential spots are cool; in Josefstadt it is 0%. 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?
The official Vienna urban climate analysis (MA 18/22, CC BY) models the heat load of every location from land use, building volume and vegetation. wohnwahn reads this map 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 Vienna 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 September 2026).
