Snow in the Big Easy: Unpacking the Rarity of New Orleans Snowstorms

New Orleans, Louisiana is renowned for its sweltering summers, rich cultural heritage, and iconic Mardi Gras celebrations. However, the city's subtropical climate rarely witnesses a blanket of snow. As a result, residents and visitors alike are often left wondering when the last snowfall occurred in the Big Easy. In this article, we'll delve into the history of snow in New Orleans, exploring the factors that contribute to the city's rarity and examining past instances of snowfall.

New Orleans is situated in a region where cold air masses from Canada rarely penetrate, making snowfall an unlikely occurrence. The city's proximity to the Gulf of Mexico and the warm waters of the Mississippi River create a humid subtropical climate, characterized by mild winters and hot, humid summers. As a result, the National Weather Service defines snow as a rare weather event in the New Orleans area, with only about 2-3 inches of snowfall occurring every 2-3 years.

History of Snowfall in New Orleans

New Orleans has experienced snowfall only a handful of times in its history. The most notable instance occurred on January 28, 1899, when a winter storm dumped 6 inches of snow on the city. This was followed by a smaller snowfall on February 14, 1967, when 1 inch of snow fell. The most recent notable snowfall occurred on January 25, 1977, when 1-2 inches of snow fell.

Factors Contributing to Snowfall in New Orleans

Several factors contribute to the rarity of snowfall in New Orleans:
