Hoch summer meets thunderstorms: Baden-Württemberg is preparing!

The summer in Baden-Württemberg is currently evident from its ambiguous side. On Saturday, June 13, 2025, we initially expect high summer temperatures before we are violent thunderstorms into the house. According to the forecasts of the German Weather Service (DWD), we can look forward to temperatures between 30 and 35 degrees, even up to 36 degrees on the Rhine. But that is only the calm before the storm, because for the evening there are strong thunderstorms that could come up with downpours of up to 40 liters per square meter and thus bring local flooding and full basement. This turbulent weather situation is supposed to calm down on Monday night, and Sunday brings cooling to 24 to 28 degrees, but remains humid.

But there is another factor that could influence our well-being in the coming days-the UV index. On Saturday he expects high values ​​between 8 and 10, which indicates a strong radiation exposure. The DWD recommends that you are in the shade with such high UV values ​​and use suitable sun protection. On Sunday, however, the UV index is expected to lower due to the announced rain shower. The UV index describes the expected daily top level of UV radiation and gives a clear warning how quickly a sunburn can occur on unprotected skin.

How does the UV index forecast work?

In order to offer us a precise prediction of the UV index, the meteorologists use data from different sources. These predictions are based on hourly data from the global weather forecast ICON and the European Weather Forecasting System Cosmo-EU. Ozon forecasts from the Royal Dutch Meteorological Institute are also included. The common goal of this cooperation is to prepare us as best as possible for the weather conditions. For today and the following days, the platform of the DWD offers hourly predictions that link the latest data from meteorological measurements. If you want to find out more about this, you will find the most important information on the DWD.

So be warned and have ready - from midsummer feeling to storm darkness, everything will be possible in the next few days! On Sunday you may be able to take a break again after cooling. Until then: Enjoy the warm hours, but also look into the clouds, because summer loves its surprises.

For more information about the UV index and the weather forecast, we recommend that the DWD (DWD) and the Federal Office for Radiation Protection (BFS) to visit.
