Vienna’s inner city is preparing for several nights of unusually high temperatures this weekend. Forecasters predict minimum temperatures will remain between 25 and 27 degrees Celsius, qualifying as “tropical nights.” This forecast indicates a continuation of a trend towards more frequent heatwaves and warmer nights in the region. The increasing number of both heat days and tropical nights is raising concerns about urban heat island effects and potential health risks for vulnerable populations. Authorities have not yet issued specific heat warnings, but residents are advised to take precautions against the heat. The sustained warmth is expected to continue through the weekend period. This follows a pattern of rising temperatures observed in recent years.
