A chapter in itself
Munich’s weather is a whole chapter in itself. Looking at tables indicating average monthly temperatures in travel books may well turn out to be a waste of time.
Generally, the winter months of December to March tend to be the coldest, but temperatures do vary a great deal each year and even those months may offer some milder days with lots of sunshine. The same goes for the supposed summer months. Although generally much warmer, they may also include weeks of rain or, in the mountainous regions, even snow.
From 28°C to snow in a week
Whereas in the wintertime it hardly snows in the northern or coastal areas of Germany, the situation may be quite different in the southern or Alpine states. This is also where the most pronounced temperature changes may occur. For example, the temperature in Munich on 7 October 2009 reached 28°C, but by a week later, it had plummeted to 0°C with snowfall.
So when is the best time to travel to Germany if you wish to avoid inclement weather? Although Germany has its charms even in the wintertime, your safest bet would be to come either in spring (April, May or June) or in autumn (September or October).
