Humid heat and violent thunderstorms: This is what Sunday will be like in Vienna!

On Sunday, July 5, 2025, the people of Vienna can expect unsettled weather with an exciting mix of humid heat and strong thunderstorms. According to 5min.at, the first rain showers are on the agenda early in the morning, which will then be replaced by an increasing tendency for thunderstorms as the day progresses. Repeated thunderstorms, locally very strong, are to be expected, especially in the afternoon. In between, however, you can also look forward to sunshine, which is sure to brighten the moods of the city's population.

The temperatures rise to up to 31 degrees. Early in the morning the mercury is already at a milder 18 degrees, but the high humidity makes the weather feel extremely humid. The weather report describes this climate as quite oppressive, which is certainly a real challenge for many.

Severe weather warnings for Vienna

The warnings for the region should not be underestimated. The data from wetter.com shows that wind gusts at speeds over 50 km/h are issued - this is only warning level 1. For stronger gusts of over 65 km/h, the warnings are even raised to level 2. In the worst case, experts expect storms in which gusts of up to 140 km/h can be registered. These weather conditions could be dangerous, particularly at higher altitudes.

In addition, heavy rain is also expected. A severe weather warning can be expected if precipitation reaches 25 l/m² in one hour (warning level 3). This suggests that the combination of heat and heavy rain will not only be unpleasant but also potentially dangerous.

The climate challenges in Austria

It is precisely in such weather conditions that the urgency of climate change becomes clear. The second Austrian assessment report on climate change shows that Austria is warming more than twice as fast as the global average. Since 1900, the temperature has increased by around 3.1 degrees Celsius. This not only leads to heat waves and droughts, but also to extreme rainfall, which increases the risk of floods and mudslides.

According to the report, the effects of climate change are serious and affect all areas of life and the economy. Vulnerable groups such as older people and people with health restrictions are particularly at risk. Therefore, quick action is required. The minimum requirements for the future are the exit from fossil fuels and the electrification of transport and industry. This is the only way to effectively address greenhouse gas emissions, which, despite certain reductions, are not sufficient to achieve the EU climate targets.

Ultimately, it shows that it is both ecologically and economically wise to invest in climate protection measures. These can not only improve the quality of life, but also strengthen resilience to global crises.

So for the Viennese on Sunday it's time to pay attention to the weather warnings, prepare for changeable weather, and maybe don't forget your umbrella!
