The best time to visit Luxembourg City

In short

The best time to visit Luxembourg City is late spring (May and June) and early autumn (September), when the weather is mild, the UNESCO-listed Old Quarters and casemates are pleasant to explore on foot, and crowds are thinner than in high summer. Peak season runs July and August, while winter is quiet and cold, though December glows with Christmas markets. For a balance of good weather and manageable crowds, aim for the shoulder months.
