A week of temperature records

Following the record-breaking heatwave in late June/early July, countless temperature records were broken in Austria between 3 and 6 August during a further heatwave. The persistently high temperatures and the lack of rainfall – particularly in the east – are also continuing to exacerbate the drought.

To illustrate the ongoing heatwave, here are a few peak figures from last week:

  • Temperatures of 40° Celsius or higher were recorded at 11 weather stations last week.
  • A new station record (maximum temperature) was set at 63 weather stations.
  • The warmest night since records began was recorded at numerous weather stations.
  • No rainfall at all was recorded last week at 22 monitoring stations in Burgenland, Lower Austria and Vienna.
  • Temperatures of 40° Celsius were recorded on three consecutive days last week.
  • Since 1767, there have been 7 days in Austria with temperatures of 40° Celsius or higher: one in 2013 and six this year.
