Returning summer season approaches
Germany's Summer Weather Forecast: Sporadic Heatwaves and Intermittent Cooler Periods
Germany's summer weather in 2025 is expected to be a mix of heatwaves and cooler periods, according to recent forecasts. The country has already experienced brief spells of extremely high temperatures, with some regions reaching up to 37–40°C in early July, followed by cooler conditions [1][4].
On Wednesday, the south and center of Germany will enjoy sunshine and maximum temperatures of up to 26 degrees. However, on Thursday, the maximum temperature along the coast will be between 20 and 25 degrees, making it a bit cooler [2]. In the northwest of Germany, there could be individual showers during the day, while the northern parts of the country will see temperatures around 20 degrees [3].
On Thursday, temperatures will rise into the summer range (25-30 degrees) across almost the whole country, according to meteorologist Marco Manitta from the German Weather Service (DWD) [5]. The far north of Germany, however, will be noticeably cooler and cloudier compared to the south, with temperatures between 21 and 27 degrees [3].
From Friday until Sunday, the overall impression of the weather in Germany remains beautiful, but the risk of thunderstorms will increase, especially in the west and south. These thunderstorms are expected to be localized incidents [6]. In the north of Germany, it will remain changeable with isolated showers, brief thunderstorms, and temperatures around 20 degrees [3].
In an interesting twist, on Friday, temperatures in the area south of the Main and Mosel rivers will exceed 30 degrees [4]. Meanwhile, in the south of Germany, the weather will be dry and sunny all day on Friday [6].
The summer so far has featured a pronounced westerly jet stream pattern, bringing variable weather, including cool and rainy spells alongside occasional hot days [2]. Mid-range models indicate that another heatwave with temperatures in the 40s °C could return and potentially last into mid-August 2025, although the pattern is expected to be unstable with fluctuations rather than continuous extreme heat [3].
In summary, the hot summer weather in Germany in 2025 is likely to continue sporadically with heatwaves possibly extending into mid-August but with intervening periods of cooler or unstable weather rather than a prolonged, uninterrupted heatwave [1][2][3]. The German Weather Service (DWD) predicts temperatures around 30 degrees before the weekend for most of Germany [5].
More heatwaves might be on the horizon, as the German Weather Service (DWD) predicts temperatures around 30 degrees before the weekend for most of Germany, continuing the pattern of sporadic hot weather observed throughout the summer. Even weather-forecasting models suggest a potential return of another heatwave with temperatures reaching the 40s °C in mid-August 2025.
