Initial account: Excessive heat observed on Friday
Hot, sticky days ahead! It looks like the southwest of Germany is in for a scorcher this Friday the 13th, with Wolfach leading the pack at a sweltering 34.7°C (94°F) and Rheinstetten hot on its heels at 34.6°C (94°F). The German Weather Service gave the lowdown to the German Press Agency in the evening.
In the sweltering southwest, meteorologists predict high humidity levels to compound the heat. They're forecasting a tropical night across the west, meaning temperatures won't dip below 20°C (68°F) in places like Cologne, Düsseldorf, Aachen, and Freiburg.
Saturday's set to be another hot one, with heat stress expected to be particularly strong in the west and southwest—just what we need. From afternoon onwards, the weather service anticipates individual thunderstorms popping up in the west, northwest, and southern highlands—and they could get heavy. There's even a local risk of severe weather, especially with the rain.
Sadly, there's no specific forecast for Cologne, Düsseldorf, Aachen, and Freiburg on a Saturday in June 2025. But based on typical June weather, expect temperatures to range from the mid-70s to mid-80s Fahrenheit (23°C to 30°C) and occasional thunderstorms, often associated with heat waves. Each city has its own unique weather, though, with Cologne and Düsseldorf typically sharing a temperate climate, Aachen experiencing slightly cooler temperatures due to its proximity to the Atlantic, and Freiburg enjoying warmer temperatures thanks to its location near the Black Forest.
For the most accurate and up-to-date forecasts, be sure to check local weather services or apps like AccuWeather or the German Weather Service (Deutscher Wetterdienst) shortly before your visit. Stay cool, folks! It's gonna be a hot one!
The surge in temperatures and humidity levels might impact the environmental science of the area, as experts are concerned about potential heat stress. The weather patterns in the coming days are reminiscent of tropical weather conditions, affectively choosing the Southwest of Germany for a weekend science experiment, so to speak.
