Austria Shatters All-Time Heat Record Twice in 3 Days
Austria’s national temperature record fell twice within three days this week, as an extraordinary heatwave pushed the country past 41°C for the first time in recorded history.
The record first broke on Tuesday, when Vienna-Stammersdorf hit 41.0°C, surpassing the previous national all-time high of 40.5°C, set in Bad Deutsch-Altenburg, Lower Austria, back in August 2013. That record had stood for 13 years. It didn’t last even three days: on Wednesday, Bad Deutsch-Altenburg itself reclaimed the top spot, this time at 41.2°C.
A summer already breaking the mold
Meteorologists say this week’s extremes cap off an unusually intense stretch. Monday had already marked the first time in Austria’s measurement history that all three summer months, June, July, and August, each recorded at least one reading of 40°C or higher somewhere in the country.
ORF meteorologist Manuel Oberhuber said as early as Monday night that August 4 looked set to enter Austria’s weather history books. Ubimet meteorologist Nikolas Zimmermann described the summer’s temperature trajectory as “unfassbar”, unbelievable, noting that forecast models had repeatedly underestimated the actual peak temperatures, largely because of exceptionally dry soil, which heats up faster and holds less moisture to cool the air.
Nights offering no relief
The heat hasn’t eased after dark either. Along with the daytime record, Austria also recorded its warmest night ever measured, with lows only dropping into the high 20s Celsius depending on location, several degrees above what would normally count as a mild summer night, let alone a low. Meteorologists warn that when nighttime temperatures stay this high, the body gets no chance to recover, a particular danger for elderly people and those with chronic health conditions.
Drought conditions compounding the heat
The extended heat and dryness are also reshaping Austria’s landscape in real time. In Upper Austria, lakes including the Attersee, Mondsee, and Wolfgangsee have dropped to unusually low water levels, while the Traunsee and Hallstätter See have risen instead, fed by accelerated glacier melt rather than rainfall. Industry has felt the strain too, with steelmaker voestalpine among the companies managing operational impacts from the heat.
This follows a winter that saw the opposite extreme: severe cold warnings and record-low temperatures in the Waldviertel region earlier this year, underscoring how wide Austria’s weather swings have become within a single year.
What comes next
Weather experts say conditions are expected to ease starting Thursday, bringing the most intense phase of the heatwave to a close. GeoSphere Austria, the country’s official meteorological and geophysical service, continues to monitor conditions and issue heat warnings as needed.
