Austria recorded 1,008 heat-related deaths during the summer of 2026, the highest number since monitoring began in 2017. The Ministry of Health reported these findings on November 9, 2026, following the nation's hottest summer in recorded history.
The AGES mortality monitoring estimated deaths from June to September using a statistical model with an uncertainty range of 637 to 1,293. Vienna saw 229 fatalities, while Lower Austria and Upper Austria reported 223 and 190 deaths respectively.
The record mortality follows extreme temperatures, including a new national high of 41.2 degrees Celsius in Bad Deutsch-Altenburg. While heat is rarely listed as a direct cause of death, the model links rising temperatures to increased mortality rates.
