Heatwave Expected in Southwest Germany as Temperatures Soar

Thu 18th Jun, 2026

Germany is bracing for a period of intense heat, with meteorological forecasts indicating the arrival of the hottest days of the year so far. After several days marked by unstable weather, including rainfall and scattered showers, a significant rise in temperature is anticipated to begin on Thursday. The German Weather Service (DWD) has issued official heat warnings for large parts of southwest Germany.

Regions affected by the warnings include Baden-Württemberg, Rhineland-Palatinate, Saarland, as well as sections of North Rhine-Westphalia, Hesse, and Bavaria. The warnings are set to be in effect from 11:00 to 19:00 on Thursday, highlighting the expected intensity and duration of the heatwave. According to meteorological assessments, a heatwave is characterized by several consecutive days of unusually high thermal stress, increasing the risk of heat-related health issues, particularly for vulnerable groups such as the elderly and those with pre-existing medical conditions.

The DWD applies a dedicated heat alert system, which evaluates not just outdoor temperatures but also the perceived temperature and potential indoor heat accumulation. This comprehensive approach aims to provide timely advisories and minimize health risks during periods of extreme heat. Meteorologists recommend measures such as maintaining adequate hydration, consuming light meals, and minimizing exposure to direct sunlight during peak hours. Residents are also urged to keep living spaces as cool as possible and to monitor updates on the heat situation regularly.

On Wednesday, temperatures in southern Germany already exceeded 30 degrees Celsius in many areas. Müllheim in southern Baden recorded the highest temperature nationwide at 32.7 degrees Celsius, based on preliminary data from the DWD. Comparable temperatures were measured in Rheinfelden and Konstanz, both located in Baden, where thermometers reached 32 degrees Celsius. These figures, while notable, remain below previous national records.

The highest temperature ever recorded in Germany occurred on 25 July 2019, with readings of 41.2 degrees Celsius in both Tönisvorst and Duisburg-Baerl. For the month of June, the record stands at 39.6 degrees, measured in Bernburg, Saxony-Anhalt, on 30 June 2019. In the current year, the previous peak was 33.4 degrees Celsius, observed in Waghäusel-Kirrlach, Baden-Württemberg, on 26 May.

The DWD's warnings underscore the importance of preparedness during extreme weather events. Residents in the affected regions are advised to pay close attention to updates and to implement recommended precautions to safeguard their health and well-being. The ongoing monitoring and dissemination of information by the DWD aim to mitigate the impact of the heatwave and support communities through the upcoming period of elevated temperatures.

As temperatures continue to rise, local authorities and health organizations are prepared to respond to potential increases in heat-related illnesses. Public awareness campaigns focus on reducing risks through practical actions, such as seeking shade, avoiding strenuous outdoor activities during midday, and caring for those who may be especially susceptible to heat stress.
