Germany Weather Forecast for the Second Half of August
The weather forecast for Germany from Wednesday, August 13 to Sunday, August 17, 2025, indicates a warm and sunny second half of the week, with some variability between the north and south, and a chance of precipitation, particularly in the south.
Temperature
In northern Germany, temperatures during the daytime will range from 24 to 28 degrees Celsius, while at night, they will hover around 11-16 degrees. By mid to late week, temperatures are expected to remain in the mid to upper 20s, with highs possibly reaching close to 28-30 degrees on warmer days. Southern Germany will experience similar warm summer temperatures, with daytime temperatures in the mid to high 20s, with slight variations day to day but generally warm.
Precipitation and Thunderstorms
Northern Germany will experience mostly moderate relative humidity (about 85-100%), which suggests some chance of rain or showers, but no explicit indication of strong thunderstorms. In contrast, southern Germany has a higher chance of rain and showers, especially in mountainous or more continental areas. Thunderstorms are more common in southern Germany during summer afternoons or evenings due to heat and orographic effects, but no exact severe thunderstorm warnings are noted in present forecasts.
