Buffalo, New York, holds a reputation as one of America’s snowiest major cities, rooted in documented meteorological data and its unique location near the Great Lakes. Understanding Buffalo’s winter climate requires examining established records. This analysis provides the city’s average snowfall figures, explores the specific weather phenomenon responsible for it, and examines the historical variability of its winter seasons.
The Measured Annual Snowfall
The official, long-term average annual snowfall for Buffalo is approximately 92 inches. This total is measured at the Buffalo Niagara International Airport, the official recording station for the area. This average is equivalent to seven feet and eight inches of snow every year.
This amount places Buffalo considerably above the national average for populated areas. Many major cities that experience winter weather receive less than half of Buffalo’s annual total. The consistent volume of snowfall means snow cover is common from late December into early March.
The Role of Lake Effect Snow
The meteorological explanation for Buffalo’s high snowfall average is the phenomenon known as Lake Effect Snow. This process begins when frigid, dry air masses move across the comparatively warmer, unfrozen water of Lake Erie. As the cold air travels over the water, it picks up moisture and heat from the surface.
This warmer, moisture-laden air rises, cools as it meets the colder air above, and condenses to form clouds downwind from the lake. When these clouds reach the land, the air cools rapidly and deposits the moisture as snow, often in intense, narrow bands. Over half of Buffalo’s annual total snowfall is attributed to this localized lake effect mechanism.
The location of these snow bands is governed by the prevailing wind direction, which influences which communities are most affected. Due to typical wind patterns, areas south and southwest of the city often receive significantly more snow than the city center. The most intense period for lake effect snow peaks in December, but the phenomenon virtually halts once Lake Erie freezes over, typically in mid-to-late January.
Historical Records and Seasonal Variability
Buffalo’s snow season typically begins with the first measurable snowfall in November, and the last usually occurs in April. The months between May and September are generally free of snow accumulation. However, the annual total is subject to extreme year-to-year variation, making the average a less reliable predictor for any single winter.
The season with the highest recorded snowfall total occurred during the winter of 1976–1977, which saw 199.4 inches of accumulation. In contrast, the least snowy season on record was the winter of 2011–2012, which recorded only 36.7 inches. This wide range demonstrates the instability of the area’s winter weather patterns.
A recent example of extreme variability was the December 2022 Christmas Blizzard, which illustrated the localized intensity of lake effect storms. During that event, the Buffalo airport recorded a multi-day total of 51.9 inches of snow, with nearby communities like Snyder receiving up to 56.5 inches. These intense, short-duration events often contribute a large portion of the annual snowfall.
