Minnesota experienced an extraordinary burst of October heat over the weekend, with temperatures climbing into the 80s and even reaching 91°F in some locations. Several cities shattered long-standing daily temperature records, bringing conditions that felt more like summer than mid-autumn. From Mankato to the Twin Cities, the unusual warmth reflected a broader weather pattern affecting the Upper Midwest. However, the record-breaking temperatures were not expected to last, as cooler air and a chance of rain approached the region. These five locations stood out during an unusually warm October weekend.
Mankato Reached a Remarkable 91 Degrees
Mankato delivered one of the weekend’s most striking temperature readings, reaching 91°F on Sunday, October 11, 2026. The reading broke the city’s previous October 11 record of 86°F, which had been recorded in both 1962 and 1976. Temperatures this high are unusual for Minnesota in October, when the state typically begins its transition toward colder autumn weather. The broader region experienced an exceptional burst of warmth as southerly winds pushed warmer air northward. However, the heat was short-lived, with a cold front expected to bring cooler conditions across Minnesota as the week progressed. Mankato’s record was part of a wider pattern of unusually high temperatures that affected several locations across the Upper Midwest.
The Twin Cities Set a New October 11 Record
The Twin Cities experienced summerlike temperatures in the middle of October, with the official high reaching 90°F on Sunday. This surpassed the previous October 11 record of 85°F, established in 2015. The reading was particularly notable because it marked the latest date on record that the metropolitan area had reached 90 degrees. The Twin Cities had also experienced exceptional warmth on Saturday, October 10, when the temperature reached 90°F and tied the existing daily record from 1928. A combination of warm air moving northward, strong southerly winds, and a developing weather system over the Dakotas contributed to the unusual conditions. A cold front moving across Minnesota was expected to end the stretch of summerlike weather and return temperatures closer to seasonal levels.
Eau Claire Broke a Longstanding October Temperature Record
Although it sits just across the state line in Wisconsin, Eau Claire was among the regional locations that experienced record-breaking October heat over the weekend. The city reached 88°F on Sunday, October 11, surpassing its previous daily record of 85°F, set in 1930. The reading reflected the same broader weather pattern affecting Minnesota, where warm air and persistent southerly winds pushed temperatures far above normal for the season. Such warmth is especially unusual in October, when shorter days and declining sunlight generally help temperatures trend downward. The record also highlighted how weather systems can affect large areas rather than stopping at state borders. As a cold front advanced eastward, cooler air was expected to spread across the region, with scattered showers possible in parts of Minnesota.
Rochester Experienced Unseasonable October Warmth
Rochester reached 86°F on Sunday, October 11, breaking its previous record high of 84°F for the date, established in 2015. The temperature was particularly striking because average highs in Minnesota typically decline considerably by the middle of October. Instead, Rochester experienced conditions more commonly associated with late summer. The warmth developed as a broader area of high pressure and southerly winds helped transport warmer air into the Upper Midwest. Rochester was also among the locations being watched for potential record temperatures before Sunday’s readings were confirmed. The unusually warm weekend was not expected to last, however. A cold front moving across the state was forecast to bring cooler air, increased cloud cover, and opportunities for rain during the following week.
St. Cloud Continued Its Record-Breaking Weekend
St. Cloud experienced extraordinary October warmth on both Saturday and Sunday, making it one of the most notable locations in the weekend’s weather story. On Saturday, October 10, temperatures reached 90°F, breaking the previous October 10 record of 88°F set in 1928. The city then recorded a high of 85°F on Sunday, October 11, surpassing the previous daily record of 83°F established in 2015. Two consecutive days of record-breaking temperatures are unusual for Minnesota in the middle of autumn, when cooler weather generally becomes more common. Meteorologists attributed the broader regional warmth to southerly winds and a weather pattern that allowed warm air to spread northward. The arrival of a cold front was expected to bring temperatures back toward seasonal averages by the middle of the week, ending the unusual stretch of October heat.
