Is Vienna Getting Hotter?
Vienna has warmed 2.3 degrees since the 1900s, placing it in the upper tier of global cities for warming. The record spans 172 years and the trend is clear.
What stands out is the pace of change. Most of the warming has been concentrated in the last few decades, with the rate accelerating from the 1980s onward.
Average Annual Temperature by Decade
Vienna's 2.3 degree warming since the 1900s makes it one of the faster-warming European capitals. The city's long record, stretching back to 1855, shows a familiar pattern: relatively stable through the early 20th century, followed by a sharp uptick from the 1980s onward. Vienna's inland position, far from any oceanic moderating influence, makes it particularly sensitive to continental warming patterns. Summer heatwaves have become notably more frequent and intense since the turn of the century.
Compared to other major world cities, Vienna's warming is notably above average.

About This Data
Temperature data on this page comes from the Global Historical Climatology Network version 4 (GHCN v4), maintained by NOAA's National Centers for Environmental Information. GHCN v4 contains monthly mean temperature data for over 25,000 stations across the globe, with records dating back to the 18th century for some stations. The data has been quality-controlled and homogenised using the Pairwise Homogeneity Algorithm to remove artificial discontinuities from station moves, equipment changes, and observation practice changes.
Vienna's primary station is Wien, with records spanning 1855-2026. The "change" figures compare each decade's average to the 1900s baseline. Note that some of the warming in large cities is attributable to the urban heat island effect rather than regional climate change alone. The figures shown here include both components, as they represent what the city actually experiences.
NASA GISTEMP analysis, which processes GHCN v4 data, is a product of NASA Goddard Institute for Space Studies. It is produced as a US Government work and is in the public domain.
