The current heatwave has a firm grip on Germany, leading to extreme temperatures. According to the German Weather Service (DWD), a peak of up to 42 degrees Celsius is expected this coming weekend. In light of these extreme weather conditions, Deutsche Bahn advises against non-essential travel. Travelers should prepare for possible delays and disruptions in train services, as severe thunderstorms are also looming. The combination of extreme heat and thunderstorms can compromise the safety of travelers, so it is advisable to reconsider planned trips and possibly postpone them.
