Do you need to know, when is the best time to go to Baden-Württemberg? Then you should take a look here, what weather you can expect there during the year.
Baden-Württemberg is part of Germany. Germany is quite a large country, so the climate is diverse. Generally the climate of Germany is temperate, it is marine in the north. You can expect cool, sometimes cloudy and wet winters, and mild summers. You would probably expect a warmer climate in the south, but don't forget the Alps, which prevent much of the warmer Mediterranean air to blow up into southern Germany. Weather in Alps is usually colder than in lowlands, of course. And it is often very cold at the peaks.
