Baden-Württemberg in May

May through October offers the best weather balance, but each season brings different advantages. Late spring (May-June) means mild temperatures perfect for hiking, plus asparagus season in local restaurants. Summer brings crowds to Heidelberg and the Black Forest, but also outdoor festivals and long daylight hours for sightseeing. September and October deliver gorgeous fall colors in the forest, plus harvest season in wine country. Winter skiing in the Black Forest works for families, though don't expect Alpine conditions. Christmas markets in Stuttgart and Heidelberg create magical December atmospheres, but book accommodations early. Baden-Baden's thermal spas feel especially appealing during cold months. Avoid major holidays when Germans flood the Black Forest — Easter week gets particularly busy.
