Frankfurt is facing the hottest day ever – heat record in danger!
A heat wave is looming in Hesse, which not only creates intense heat, but also brings with it the risk of health risks. Next Wednesday, July 2, 2025, the hottest day since weather records began in Hesse could be recorded. According to the German Weather Service (DWD), temperatures of up to 40 degrees can be expected. These extreme values could even exceed the previous record of 40.2 degrees, which was measured in Frankfurt's Westend on July 25, 2019 fr.de reported.
In the run-up to the heat peak, there was already an increase in rescue missions in Wiesbaden, where on Monday, June 30th, the rescue services were deployed 163 times, accompanied by 15 fire brigade missions, all in the context of heat complaints and smaller forest fires. This already points to the health risks associated with such extreme temperatures.
Forecast and weather conditions
The forecast for July 1st calls for temperatures to reach the highs of 38 degrees. Wednesday night will remain tropically warm, with minimal cooling between 18 and 23 degrees. On July 2nd, temperatures could reach the highest values, particularly in Ried in southern Hesse and the Frankfurt area, which will further inflame the weather situation. Meteorologist Mark Eisenmann highlights that the combination of strong temperatures and high humidity increases heat stress. This is a warning that also applies to the entire Hesse region, as heat warnings have now been declared nationwide, after previously only being in force for the southern half hessenschau.de emphasized.
Another worrying element of this heat wave is the ongoing drought, which further increases the risk of wildfires. This is particularly alarming as there have already been small fires caused by the high heat and the associated dryness. The health risks cannot be neglected either, as high temperatures lead to an increased risk of sunburns and increased ozone pollution in the air.
A look at June
June 2025 turned out to be particularly warm and dry, with a clear north-south contrast in Hesse: While southern Hesse recorded around 18 summer days and 8 hot days, northern Hesse only recorded 10 summer days and 3 hot days. The average temperature for June was 18.5 degrees, which is 3.1 degrees above the reference value of 15.4 degrees from 1961-1990. It is important to note that every June since 2010 has been classified as too warm.
The extreme heat will be followed by a cold front starting Thursday, which will drop temperatures to a more moderate level between 22 and 29 degrees. But until then, everyone is asked to prepare for the upcoming high temperatures and take appropriate measures.
