Germany is classified as a “Temperate” country when it comes to temperatures, which puts it right in the middle of the climate scale meaning it isn’t very extreme and can be (comparibly) mild each season. Areas along the Northern Coasts by the Baltic and North Seas will tend to have a bit more humidity than other parts of Germany but nothing extreme. Even on days with higher humidity levels, when the average summer day is in the 80s(F) (Upper 20s C) even with a high humidity level, the “Feels Like” temperature is often still very bearable.
