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.

Official Vienna urban climate analysis (heat load), evaluated per 250 m cell · as of: August 2026
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.

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.
Ranked by the median heat load of inhabited residential cells. Linked: the full district profile in the atlas.
Method: official heat-load map (urban climate analysis, MA 18/22, 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.

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).

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.
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.
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.
Currently 11 listings on wohnwahn sit in an officially cool spot. Each card shows the heat load of its location.
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.
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.
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).
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 (tree cadastre City of Vienna) and the water proximity of the location.
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 August 2026).
