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. Its Marine West Coast Climate, or "Cfb" according to the Köppen climate classification, ensures that it experiences relatively mild and temperate weather throughout the year, without any extremes in temperature. Annually, precipitation ranges from 500mm (19.69") to 2500mm (98.43"), with the likelihood of heavier rainfall where onshore winds meet the elevated terrain. 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. Average temperatures during winter remain mild, and summers are moderated by occasional breezes.
