When Is the Best Time To Visit Luxembourg?
The answer to the question of what is the best month to visit Luxembourg depends on what you are interested in doing during your stay. Here you can see an overview of each month and its typical weather conditions.
Tourist Season in Luxembourg
Luxembourg is best visited during the summer months, from June to August, then we can count on warm and sunny weather. Long and not too hot days are the ideal time for sightseeing and hiking along the mountain trails in the Ardennes. However, even in the summer there is no avoiding the rain, which appears quite often, but usually does not last long.
Spring (April-May) and autumn (September-October), despite the fact that it is a bit cooler and the sun is in the sky for a much shorter period of time, is still a good time to travel to Luxembourg.
The winter months, from November to March, are outside the tourist season. Due to falling temperatures, rain or snowfall and high cloud cover, a visit during this period can be much less enjoyable.

November - March
Nov | Dec | Jan | Feb | Mar |
In November, the weather deteriorates and the cold starts to become noticeable (about 8°C). More and more days are cloudy and foggy.
The winter months (starting in late November and early December) bring a drop in temperatures to 0°C - 2°C, and in the Ardennes to several degrees below 0°C. Humidity increases and rain or drizzle can be expected more often. Especially in the mountains, snowfall is also possible, however, the snow cover does not last very long.
In general, winters in Luxembourg are fairly mild, big frosts usually do not occur even in the higher parts of the mountains. On the other hand, strong winds and cloudy and cold days are not conducive to sightseeing, so the winter period is outside the tourist season.
