Mount Washington, New Hampshire — As autumn temperatures begin to drop across the Northeast, thoughts of winter weather are returning. Although widespread snowfall typically arrives later in the season, historical weather records show that some locations have experienced their first snow surprisingly early, including before fall officially begins.
From the high elevations of New Hampshire to the cities of western New York and parts of Maryland, the earliest snowfall records reveal just how unpredictable the transition from fall to winter can be.
Some locations have recorded snow as early as August and September, while others have seen measurable snowfall arrive in October. These dates offer a look at the region’s weather history as residents prepare for another cold-weather season.
New Hampshire Has Recorded Snow in August
Mount Washington, home to the Mount Washington Observatory, is known for its extreme weather and high-elevation conditions. Its exposed summit can experience winter-like weather well before many surrounding communities see their first flakes.
According to records dating back to 1935, the observatory’s first day of true snow was recorded on August 31.
The timing highlights the difference between weather at high elevations and conditions in nearby towns. Temperatures can fall sharply on mountain summits, allowing snow to develop even while lower elevations remain relatively mild.
Elsewhere in New Hampshire, the earliest measurable snowfall occurred on September 17, 1965, according to the National Weather Service (NWS).
Measurable snowfall differs from a few isolated flakes because it refers to snow that accumulates to a reportable amount. The distinction matters when comparing historical records across different locations.
Buffalo’s Earliest Snowfall Arrived in September
Western New York is familiar with heavy winter storms, particularly when cold air moves across the Great Lakes and picks up moisture. Buffalo frequently attracts attention during the winter because lake-effect snow can produce intense accumulations over relatively short periods.
However, the city’s earliest snowfall records show that winter weather can make an appearance well before the traditional start of the season.
Buffalo’s average first snowfall occurs around October 24, while its first measurable snowfall typically arrives around November 8, according to the figures provided in the original report.
The city’s earliest recorded first snowfall occurred on September 20, 1956, according to the NWS.
Rochester, another city in western New York, typically sees its first snowflakes around October 23. Its first measurable snowfall generally arrives around November 8.
These dates are historical averages and records, not predictions for the current season. Actual snowfall timing can vary considerably from year to year.
Massachusetts Recorded Measurable Snow in September
Massachusetts can experience a sharp transition from mild autumn conditions to cold, wintry weather. While significant snowfall is more commonly associated with the later fall and winter months, historical records show that measurable snow has arrived in September.
According to the National Weather Service, the state’s earliest measurable snowfall occurred on September 26, 1942, when Massachusetts recorded approximately 1 inch of snow.
Such an early event is unusual, but it illustrates that the first measurable snowfall does not always wait until temperatures remain consistently cold.
For residents, the arrival of the first flakes can be an early reminder to prepare for winter. However, a September snowfall does not necessarily indicate that the region will experience an unusually snowy winter overall.
Maryland’s Earliest Snowfall Came in October
Maryland also has a history of significant winter weather, particularly in western parts of the state, where elevation can contribute to heavier snowfall totals.
The original report lists the state’s average seasonal snowfall at 20.6 inches. It also cites a seasonal snowfall total of 262.5 inches at Keysers Ridge in Garrett County, although the winter dates accompanying that figure should be verified before publication.
Baltimore’s earliest measurable snowfall occurred on October 10, 1979, when approximately 0.3 inches fell, according to the report.

The date demonstrates that even areas farther south in the Northeast and Mid-Atlantic can experience measurable snow during early autumn.
However, snowfall records for individual cities should not be treated as statewide records. Conditions in western Maryland can differ significantly from those in Baltimore and other lower-elevation locations.
Could the Northeast See Snow Early Again This Fall?
Historical records show that early snowfall is possible, but they do not establish when the first snow will arrive this year.
The timing depends on several factors, including temperature patterns, incoming weather systems, elevation and, in western New York, the conditions that support lake-effect snow.
High-elevation locations such as Mount Washington can see snow much earlier than surrounding communities. For cities such as Buffalo, Rochester and Baltimore, the first measurable snowfall often arrives later, although individual years can bring exceptions.
Residents watching for the season’s first flakes should follow local National Weather Service forecasts for current conditions rather than relying solely on historical dates.
