Rochester residents who love the full swing of Minnesota’s four seasons have a rare weather footnote to share: the city has experienced measurable snowfall in September only twice in its recorded history.
First September Snowfall – 1942
According to data compiled by Extreme Weather, the earliest September snowfall in Rochester occurred on September 26, 1942. The National Weather Service recorded a modest 0.3 inch of snow at Rochester International Airport. While the amount was only a dusting, it was enough to surprise locals who were still expecting late‑summer warmth.
Record‑Low September Temperature
Just two days after that historic snow, the same weather service noted Rochester’s all‑time record low for the month: a frigid 22 °F on September 28, 1942. The early cold snap underscored how quickly the region can shift from summer to winter‑like conditions.
Second September Snowfall – 1961
The only other measurable September snowfall on record came on September 30, 1961, when 0.8 inch of snow fell in the city. Though still a rare event, the 1961 snow was more substantial than the 1942 dusting, giving Rochester another reminder that September weather can be unpredictable.
Why It Matters to Rochester Residents
For those who enjoy the “Land of 10,000 Lakes” lifestyle, these historical quirks are a point of local pride and conversation. They illustrate the state’s reputation for rapid seasonal changes—a factor that influences everything from gardening schedules to outdoor recreation planning.
While September snow remains an anomaly, the city’s weather history serves as a reminder to stay prepared for sudden shifts. Whether you’re planning a weekend hike, a backyard barbecue, or simply checking the forecast, keeping an eye on the sky is always wise in southeast Minnesota.
Looking Ahead
As climate patterns continue to evolve, meteorologists will watch future September seasons closely to see if early snowfall becomes more common or remains a historical footnote. For now, Rochester’s two September snow events stand as unique chapters in the city’s weather story.
