The climate of Luxembourg

Luxembourg, a small landlocked country nestled between Germany, France, and Belgium, is characterized by its undulating topography of rolling hills and verdant valleys.

While rainfall is a common occurrence, the intensity is often mild, making it a consistent presence rather than a severe disruption. Fog is a typical sight during autumn and winter months, while thunderstorms remain a rare event. Strong gales with high winds are primarily observed in the winter, contributing to the country's dynamic weather patterns.
