Minnesota’s 2026 fall colors are expected to emerge from late September into mid-October, with the progression typically starting in the far northwest and north-central parts of the state before moving southeast. Peak color generally lasts about a week in a given area, according to Minnesota Department of Natural Resources information reported by CBS News and FOX 9.
Drought could make the display less uniform. DNR forest health consultant Brian Schwingle said, as reported by CBS News and FOX 9, that severe drought can weaken some colors and cause trees to change or shed leaves earlier—or later, depending on the species. CBS News reported that more than half the state was in at least severe drought in early September and that the Twin Cities had its sixth-hottest summer in more than 150 years of records.
Conditions may differ sharply across Minnesota. The Star Tribune reported drought stress in a corridor from St. Cloud to Hinckley and southeast of the Twin Cities, where foliage could be less vivid and drop sooner than usual. The report also said summer fires in northeastern Minnesota could leave some foliage muted or brown, while trees in southwestern and southeastern Minnesota were in better condition.
Why weather changes the palette
Shortening daylight and falling temperatures initiate the seasonal process. As chlorophyll breaks down, yellow and orange carotenoid pigments become visible. Sunny days and cool, nonfreezing nights can support the formation of anthocyanins, the pigments associated with red and purple leaves, according to University of Minnesota Extension.
The weather can also affect how quickly the display develops and disappears. An early frost, freeze or snow may speed color change and leaf drop, while a prolonged warm period can delay both. The University of Minnesota’s explanation says drought and unusually warm conditions can reduce the intensity or duration of fall color, although some plants may respond differently when stressed.
Helping trees through drought
For established trees facing dry conditions, the Wisconsin Department of Natural Resources advises providing about an inch of water per week when possible. Deep watering and organic mulch can help retain moisture, offering a practical way to reduce additional stress while drought conditions persist.
Peak dates are not fixed
Peak dates are not fixed, particularly in the Twin Cities. The Star Tribune reported that the metro peak was commonly in late September about half a century ago but is now more often in mid-October; the 2025 peak came in late October. CBS News separately linked the broader shift to warmer autumn temperatures and reported the unusually hot 2026 summer in the metro.
Travelers along the North Shore can find different timing within the same trip. Explore Minnesota’s travel guidance describes an earlier peak on inland Sawtooth Mountain ridges, followed by a later display of shoreline birch and aspen that can peak as much as two weeks afterward.
Ways to check conditions
The DNR’s Fall Color Finder is the most direct way to track the season week by week. It includes reports from state parks and recreation areas, and its map and date slider let users compare current conditions with typical patterns from past years, according to KROX and CBS News. The DNR also offers a weekly Fall Color Update newsletter.
Before setting out, visitors should check park alerts, the local forecast and current access information. Fall weekends can be busy, so checking parking and reservation conditions in advance can help travelers plan, according to FOX 9.
