About Luxembourg

Luxembourg is a small, wealthy country of wooded hills, river valleys and a remarkable fortified capital. Luxembourg City sits on deep gorges with old walls and tunnels, the Moselle valley grows the country's wines, and the Ardennes and Mullerthal offer forest walking and slow villages. Spring to autumn is the most comfortable stretch for hiking and city visits; summer is warm and festive, while winter is quiet and cold, when the capital turns to museums, markets and food.

How are the Luxembourg travel scores calculated?
Every city is rated 0-10 per month using ERA5 climate normals - temperature, precipitation, humidity, daylight, and days with 6+ hours of sunshine.

Climate data: Open-Meteo ERA5 historical archive, the five most recent complete years (2021–2025). Scores are monthly averages for that window, not forecasts, and short-window precipitation can differ from longer-term normals. “Sunny days” count days with at least 6 hours of measured sunshine — they are not dry days.
