Paris Paralyzed by Record 40 cm Snowfall in Early March 1946
Paris, February 27, 2026 – Eighty years ago, in early March 1946, the city of Paris was brought to a standstill by an unprecedented snowfall, with a record-breaking 40 cm of snow accumulating on the ground. This historic event, which transformed the French capital into a veritable winter sports resort, remains the most significant snowfall recorded in Paris since meteorological observations began at Paris-Montsouris.
The extreme weather conditions were the result of a powerful snowstorm that swept across northern France. Towards the end of February 1946, a high-pressure system established itself over the Atlantic and Greenland, leading to a significant drop of polar air that enveloped northern Europe and plunged into the North Sea. South of this cold air mass, a depression formed near Portugal and then moved over France, where it lingered for several days in early March 1946. This created a strong conflict between air masses, bringing an active and persistent snow episode from the Pays de la Loire region to Belgium, with Île-de-France being particularly affected.
Unprecedented Snowfall and its Impact
The 40 cm of snow recorded in Paris was an unparalleled depth, a figure that has not been equaled in the decades since. Historical accounts suggest that a similar snow depth in the Parisian region had not been seen since the winter of 1829-1830. The snowfall was even more substantial west of Paris, reaching up to 55 cm in the Yvelines department. Archival photographs from the period vividly depict Parisian terraces completely buried under snow, showcasing the immense scale of the event.
The abundant snow, while offering a unique spectacle, also posed significant challenges. The city’s circulation was severely hampered, leading to widespread paralysis. The thickness of the snow caused roofs and glass roofs to collapse in several districts of the capital. Furthermore, the delivery of food supplies to the region was greatly disrupted, resulting in empty shelves in shops. Rail traffic also came to a halt, and city streets became difficult to navigate, leading to numerous accidents. It took several days for activities to gradually return to normal.
Paris Transformed: Skiing in the City
Despite the difficulties, Parisians, just six months after the end of World War II, embraced this exceptional episode with a unique spirit. Many residents donned skis to navigate the streets, descending the steps of the Trocadéro to the foot of the Eiffel Tower and even the slopes of Montmartre Hill. These images of Parisians skiing through the city streets have become iconic, symbolizing the resilience and adaptability of the populace in extraordinary circumstances.
Today, this event serves as a powerful reminder of the extreme weather conditions that can affect even major urban centers. It underscores the importance of historical meteorological data in understanding long-term climate patterns and preparing for future weather phenomena.
