At the height of summer, one thing decides whether your daily walk is bearable: the shade of the street trees. We ranked Vienna by the City’s tree register.
1624 street trees · a dense net of shaded avenues
Ranked from open data (City of Vienna OGD, OpenStreetMap, Wiener Linien, Statistics Austria) — not a tourist tip list.
A treeless Gründerzeit lane bakes like an oven in July; an avenue of old plane trees stays several degrees cooler — and the walk to the metro feels entirely different. We measure this not by parks, but by the trees right on the street: the shade that actually falls across your day.
The basis is the City of Vienna’s open tree register — every recorded street tree near the Grätzl centre. Importantly, street trees are not the same as parks or forest. Some green hillside by the Vienna Woods has few catalogued street trees yet plenty of greenery; conversely, a surprisingly dense net of avenues runs through the built-up districts.
Averaged over a whole district the picture blurs — the real question is your own lane. These Grätzl have the densest street trees:
An honest note: lots of street trees means shade and cooler air on the way — it says nothing about the size of the parks or how quiet the area is. Few catalogued street trees, in turn, does not automatically mean “hot”: on the city’s edge the nearby forest replaces the avenue.
On the map, the “Trees & shade” layer shows the street-tree network for all of Vienna, and the “green & shaded” search brings densely planted areas to the front. For the commute it pays to check which axis is shaded — two parallel streets are often worlds apart.

Measured by the City of Vienna’s tree register, densely planted districts like Währing, Brigittenau and Rudolfsheim-Fünfhaus lead — their broad Gründerzeit avenues are lined with trees throughout. The value counts street trees, not parks or forest.
Are lots of street trees the same as lots of greenery?
No. Street trees give shade exactly where you walk — on the pavement. Parks, forest and hillsides on the city’s edge are a different kind of green; some very green outer area has few catalogued street trees. That is why we keep the two separate.
How does shade help against the heat?
A mature tree canopy keeps the direct sun off the asphalt and cools the air through evaporation — on shaded pavements it is noticeably several degrees cooler than in the treeless lane next door. For the daily walk that makes the biggest difference.
