Luxembourg is a captivating blend of medieval fortresses, modern European institutions, and stunning natural landscapes. This small but mighty Grand Duchy offers UNESCO World Heritage sites, world-class dining with 11 Michelin-starred restaurants, and free public transportation throughout the entire country. From the dramatic Bock Casemates to the fairy-tale Vianden Castle, Luxembourg seamlessly combines rich history with contemporary sophistication.
Luxembourg has a temperate oceanic climate (Cfb) characterized by mild summers, cool winters, and rainfall spread throughout the year. The country sits at the crossroads of maritime Atlantic influences from the west and continental European patterns from the east, resulting in changeable and often grey weather particularly in autumn and winter. Summers are pleasantly warm (20-25C) but rarely hot, while winters are cold and frequently foggy with occasional snow in the northern Ardennes. Rain can fall in any month but is heaviest in November-January. Luxembourg City and the south are slightly warmer than the Ardennes north.
