Vienna sweats: The first tropical night of the year brings heat wave!

Wien, Österreich - On June 5, 2025, Vienna experienced the first tropical night of the year in which the temperatures did not drop below 20 degrees. A low temperature of 20.3 degrees was measured at Karlsplatz, while in Podersdorf (Neusiedl district) the subsequent temperatures were 20.2 degrees. This night temperature is defined as a tropical night, and the forecasts for this day pointed to possible heat days, with expected temperatures of around 29 degrees Celsius in Vienna and over 30 degrees in parts of South Styria, Graz basin and the Burgenland. 5min.at reports that such tropical nights occur more frequently, especially in the urban areas, where the heat island effect increases the temperatures.

The health effects of heat days and tropical nights are considerable. Children, the elderly and people with previous illnesses are particularly affected. Heat -related health risks should not be underestimated; According to the Ministry of Health, up to 500 people in Austria die from heat f are engines. Persistent heat can cause cardiovascular problems, which are even more intensified with increasing temperatures. Context-institut.at emphasizes that the concentration suffers at temperatures from 26 degrees from 26 degrees and the risk of work accidents increases.

economic effects of the heat

The heat not only causes health problems, but also has economic consequences. Industries are particularly affected that depend heavily on physical work outdoors, such as construction, agriculture and gastronomy. At lunchtime and afternoon, customers often fail to materialize in these sectors, which leads to loss of sales. In addition, the persistent drought influences agriculture by reducing water availability and reducing the yields. context-institut.at reports of the challenges that persistent droughts have broken, such as the susceptibility of spruces for pests due to lack of water.

forecasts and future risks

The forecasts show that the number of tropical nights and hot days will increase due to climate change. The German Weather Service defines "hot days" as such with temperatures above 30 degrees. Between 2000 and 2023, the summer 2003, 2015, 2018 and 2022 were affected by an increase in these hot days. The health risks are increasing because any further temperature increase can bring heat -related mortality from 1 to 6 percent. [Environmental Bundesamt.de] (https://www.umweltbundeamt.de/daten/umwelt-gesundheit/gesundheitrisiken- Derhiten) refers to the increase in health pollution through the simultaneous occurrence of hot days and tropical nights as particularly problematic.

The appreciation for cooler places during the summer months will probably increase in the next few years. In cities in particular, measures should be taken to counteract the heat and to ensure the quality of life of the population. Heat waves, which include several hot days and tropical nights, are not only a challenge for health, but also for economic stress, and require corresponding measures at local and national level.
