Heat wave is approaching NRW: 39 degrees on the hottest day of the year!
We are facing a hot summer, and the weather in North Rhine-Westphalia doesn't do things by halves. Today, June 29, 2025, the forecasts are hot: meteorologists are throwing out their heat warnings and expect a temperature of 37 degrees Celsius on Tuesday. Wednesday picks up the pace and finally brings highs of up to 39 degrees Celsius in the Rhineland, which marks the hottest day of the year. That reports stern.de.
But the scorching heat also has its downsides. We can expect temperatures of 33 degrees Celsius as early as Monday, and the nights from Tuesday promise tropical nights with temperatures over 20 degrees Celsius. Although thunderstorms are expected in the evening, they are unlikely to provide much-needed cooling. At least there is a ray of hope on Thursday - a slight cooling and rain are on the agenda.
Preparing for the heat wave
A new ray of hope or simply a warning – it depends entirely on your personal perspective. The North Rhine-Westphalia State Center for Health (LZG) website provides information about the health risks of heat. They provide general health information about heat warnings and it is important to be sensitive, especially when sharing this information with third parties. lzg.nrw.de also offers a newsletter for users so that they can stay up to date with important information from the last few weeks.
The health effects of heat should not be underestimated. The Robert Koch Institute (RKI) points out that particularly vulnerable groups – such as older people, pregnant women and children – can suffer from the consequences. Effective heat and health protection are therefore a must. An increase in heat due to climate change is expected in the coming decades, which makes the need for preventative protection all the more urgent.
Together against the heat
It becomes clear: the requirements for good heat protection require interaction between various authorities and ministries. The RKI is in dialogue with the Federal Ministry of Health and the German Weather Service to ensure that reliable information and preventive measures are developed. The Federal Center for Health Education and the Federal Environment Agency are also involved in these discussions.
We can only hope that cooling alternatives will be available in the coming hot days - be it in the form of shady trees, refreshing drinks or a break by the cool water. The scorching heat has called for people to think about their own health. That's why, let's overcome this heat wave together and take good care of ourselves!
