Southern Germany is has generally mild and pleasant weather throughout the year. Summers are never hot, winters are never terribly cold. This makes for an ideal place to visit where a few layers should serve you well throughout the year.

The best time to visit is during the late spring and summer; this is when the temperatures are warm with plenty of sun but never too hot. There can be occasional days of high heat but this seldom the case. August is actually the rainiest month, but generally this is attributed to a few days of heavy rainfall. Heidelberg is also among the warmest parts of Baden-Württemberg and temperatures tend to run a few degrees warmer in this ancient city.

The late fall and early winter is the true rainy season with periods of light but persistent rain for days… or even weeks on end. Snow is not common, and winters can generally be quite mild. Temperatures seldom dip below freezing during the day light hours. All in all, with its beautiful Southern German forests and mountains and old style buildings Heidelberg makes for a storybook visit right out a fairytale almost the whole year through.
