Lörrach refreshes: new fogches increase summer comfort in the city!

In the city of Lörrach, the city administration has installed new foggy showers in the city center, which have been in operation since June 15, 2025. These cooling systems are strategically located in the pedestrian zone on Senser Platz and in the Turmstrasse at Karstadt. Every day from 9 a.m. to 9 p.m., the fog shears spray fine water levers, which contributes to significantly increasing the quality of stay in the city center, especially with increasing summer temperatures. The measure is part of an environmentally friendly climate adjustment and was financed by the funding program. Verlagshaus-jaumann.de reported.

But what exactly makes these fog shots so advantageous? Comparable systems already show promising results in other cities. In Emmendingen there is currently testing to spray water lever every two minutes to reduce the ambient temperature by up to five degrees. The test run on the Schlossplatz will be carried out until the end of the summer vacation, and if the results are positive, the system could soon be used nationwide. Of course, the water consumption in the fog show is low; In Lörrach, for example, this was only 25 liters per hour during the test leave. The Baden-Württemberg City Day also supports the use of such spray systems for improving the microclimate, such as [SWR.de] (https://www.swr.de/swraktuell/baden-wuedtemberg/suedbaden/nebelduschen-prueh-lebel- towards-hitze-100.html).

Stadtklima and fog shock

The phenomenon of urban heat islands is remarkably pronounced in cities such as Lörrach and many others. The denser development and the lower vegetation ensure that the city climate have significantly higher temperatures and lower wind speeds than the surrounding area. This often leads to unpleasant hot nights, especially after sunny days. Climate change also increases these problems. Urban measures to improve the climate are therefore particularly important. In Vienna, the environmental protection department has developed various strategies since 2001 to mitigate the effects of climate change and to increase summer comfort, which is also emphasized by wien.gv.at.

The use of fog showing is only one of several solutions to counteract the summer heat problem. In the long term, natural shadow dispensers, such as trees and the removal of areas, also play a crucial role. The Karlsruhe University of Applied Sciences is currently testing alternative systems that use rainwater for cooling and are operated with solar power. Such innovative approaches could help to cool hot air selectively without waste valuable drinking water. While cities such as Vienna, Paris and Stuttgart are already relying on fogches, it can be hoped that this technology will soon be used in Baden-Württemberg and that the quality of life will be further increased in the city centers.
