Heat wave in Saarbrücken: health warning for those affected!
On August 12, 2025, the population in Saarbrücken can expect hot temperatures and some health challenges. The day will be hot and oppressive with a maximum temperature of 38°C and a felt temperature of 31°C, while the relative humidity will be at 36%. These weather conditions lead to the classification of “moderate heat stress”. The wind speed is a moderate 4 km/h and the UV index is also high at 6.53.
The weather influence on health is significant this Tuesday. During the morning hours, a low risk to general well-being as well as to various health areas such as the cardiovascular system and rheumatic complaints is reported. However, the danger increases to a high level over the course of the afternoon. This particularly affects cardiovascular problems, inflammatory rheumatic problems and even psychological and mental performance. As a result, measures for individual protection are recommended.
Health effects
The weather conditions in Saarbrücken have different effects on people's health, especially for those who are sensitive to the weather or people with existing illnesses. According to the German Weather Service (DWD), high temperatures and humidity can lead to impaired well-being in sensitive people. The afternoon is particularly risky, as the likelihood of headaches and migraines increases. There is also a low risk for asthma patients.
To alleviate the symptoms, it is advisable to go outside in the cooler morning and evening hours and make sure to drink enough fluids. Additional caution is required in road traffic, as the ability to concentrate and perform can also be impaired.
Pollen count and weather conditions
In addition to the health risks caused by high temperatures, pollen counts are the focus of attention. The current pollen report shows that mugwort and grasses are the main sources of pollen. The DWD reports low to medium pollution from mugwort, while there is no pollution recorded for alder, birch and rye. The weather conditions, which are dry and warm with some wind, favor the spread of pollen, which is why allergy sufferers should be particularly careful during this time.
In summary, it can be seen that the biological weather on August 12, 2025 in Saarbrücken brings with it both physical and psychological challenges. Fundamentally adapting behavior and activities to these conditions can help minimize the health effects. It is important to be aware of the risks and take appropriate precautions.
