Luxembourg Weather, climate and geography
Warm weather can generally be expected from May to September. Snow is not uncommon during the winter months, especially in the higher Ardennes regions in the northern half of the country, but this is less reliable than it once was, and has led to the virtual eradication of the former (albeit small) cross-country skiing industry.
The north (the Ardennes region) tends to be slightly wetter and slightly colder than the south at all times of year. As has been seen in other regions, weather patterns have become far less predictable in recent years than they used to be, and visitors should be braced for anything whenever they travel.
Restaurants, hotels and most visitor attractions in Luxembourg City remain open all year round, and there is no specific high or low season, although certain peak times such as the National Day in June, Easter and Christmas can become booked out well in advance. Many other parts of the country however experience a very distinct low season in January and February, and tourist grinds to a halt in much of the Ardennes. Many smaller hotels and some restaurants shut completely during the winter months, and establishments that remain open often have limited opening hours.
Autumn can be a good time to visit the north as the annual turning of the leaves is a wonderful and free natural spectacle, many country hotels have open fires going, and the restaurants offer seasonal menus featuring local game.
