Darmstadt and Frankfurt reach their peak temperatures during noon hours. - Forecast indicates peak temperatures in Darmstadt and Frankfurt midday
The Rhine-Main region is bracing itself for a scorching hot day on Wednesday, July 2, 2025, as temperatures in Hesse, Germany, are expected to reach record-breaking heights. According to the German Weather Service (DWD), the region is set to be the focus of the high temperatures, with temperatures in Hesse potentially exceeding 38°C[1].
Meteorologist Adrian Leyser Storm from DWD predicts that Hesse could reach an unprecedented 40 degrees Celsius on Wednesday[2]. This forecast is in line with the notable heatwave conditions reported by DWD, which has identified the Rhine-Main region as a heat hotspot[1].
At midday, several cities in Hesse, including Darmstadt and Frankfurt, had already experienced soaring temperatures. Frankfurt recorded a temperature of 35.1 degrees Celsius, while Darmstadt reached 35.7 degrees Celsius[1]. In neighbouring Michelstadt, the mercury climbed to 35 degrees Celsius, and in Fulda-Horas, the temperature also reached 35 degrees Celsius at noon[3].
In addition, the Odenwaldkreis region also saw temperatures of 35 degrees Celsius at noon[4]. These high temperatures are causing concern among meteorologists and officials, as they increase heat stress risks and pose challenges such as crop damage, energy system overload, and health impacts on vulnerable populations[1].
While exact hourly or daily temperatures for Darmstadt are not explicitly stated, it can be inferred that since Darmstadt is located within Hesse and near Frankfurt, it will experience similar very high temperatures around or exceeding 38°C on this Wednesday[1].
In summary, the forecasts highlight a significant heat risk for the region on this day, with Frankfurt, Darmstadt, and other major urban areas in Hesse likely to experience temperatures around or above 38°C, and nighttime minimum temperatures staying above 22–25°C[1]. Residents are advised to take precautions to stay safe and cool during this extreme heatwave.
| Location | Forecasted Temperature (Wednesday, July 2, 2025) | |-------------|-------------------------------------------------| | Hesse | Around or exceeding 38°C | | Frankfurt | Around or exceeding 38°C, nighttime lows above 22–25°C | | Darmstadt | Similar to Frankfurt, around or exceeding 38°C |

The Commission could discuss a weather-forecasting system alongside its proposal for a directive on the protection of workers from the risks related to exposure to ionizing radiation, as high temperatures have become a significant concern for workers in Hesse, Germany, during the heatwave on Wednesday, July 2, 2025. The workers might experience increased heat stress risks, posing challenges like crop damage and health impacts on vulnerable populations, which are the same risks that the region and its residents have been facing due to the anticipated high temperatures.
