The 2026 fall foliage season is underway in the northern reaches of the United States, with colour change already reported across the higher elevations of northern New England, the Upper Midwest, and the Rocky Mountain region. The Smoky Mountains Fall Foliage Prediction Map and the US Forest Service’s leaf tracker, which synthesise temperature and daylight data, indicate the season is tracking close to the historical average after a summer that was hot in the West but closer to normal in the East.
The progression moves south and to lower elevations over approximately six to eight weeks, meaning a traveller with flexibility can follow the colour from Vermont in early October to the Appalachians of North Carolina by mid-November.
Regional Peak Timing for 2026
New England (Vermont, New Hampshire, Maine) New England delivers the most intense colour in the country due to its mix of sugar maples, birch, and beech. The following timeline is based on current temperature data and the 2026 forecast:
- Northern Vermont and New Hampshire highlands: early to mid-October (already showing early colour as of 25 September)
- Southern Vermont (Woodstock, Stowe, Manchester): mid to late October - peak window
- Maine interior (Acadia National Park, Rangeley Lakes): mid-October
- Massachusetts Berkshires and Connecticut River Valley: late October
Mid-Atlantic (New York, Pennsylvania, Maryland)
- Adirondacks and Catskills (New York): mid to late October
- Pennsylvania’s Pocono Mountains and central ridges: late October
- Shenandoah Valley (Virginia): late October to early November
Great Smoky Mountains and Southern Appalachians The Smokies are the most visited national park in the country year-round, and the foliage season adds significant crowds:
- Higher elevations (above 4,000 feet): mid-October
- Mid-elevation trails: late October
- Lower valleys and Gatlinburg/Cherokee area: early to mid-November
Upper Midwest (Minnesota, Michigan, Wisconsin)
- Minnesota’s Boundary Waters and Superior Hiking Trail: early October
- Michigan Upper Peninsula and Traverse City: mid-October
- Wisconsin Door Peninsula: mid to late October
Rocky Mountains (Colorado, Utah) Aspens dominate the fall colour in the West, with narrow peak windows:
- Colorado Rocky Mountain National Park and Independence Pass: late September (peak window now or just past in 2026)
- Utah’s Wasatch Range and Dixie National Forest: early to mid-October
Pacific Northwest More muted than the East but still significant:
- Oregon’s Columbia River Gorge: mid to late October
- Washington’s North Cascades: mid-October
Planning Considerations
New England lodging Popular areas including Stowe, Woodstock, and North Conway see full hotel occupancy on peak weekends in October. The Vermont tourism office typically announces the busiest foliage weekends in the first week of October based on colour tracking. Booking in advance is strongly recommended for peak weekend travel.
Driving routes Several well-known routes are specifically tracked for foliage:
- Vermont Route 100 (the primary “foliage highway” running north-south through the Green Mountains)
- New Hampshire’s Kancamagus Highway (NH 112) - a 34-mile route with no commercial development and consistent high canopy
- The Blue Ridge Parkway (Virginia and North Carolina) for the Appalachian colour corridor
Foliage tracking tools The Smoky Mountains prediction map updates weekly throughout the season. The US Forest Service runs the interactive leaf tracker at the FS Fall Colors website, updated by rangers at national forests across the country.
How Weather Affects the 2026 Season
Fall foliage intensity is driven by:
- A warm, dry late summer (producing more sugars in the leaves)
- A cool, dry autumn with clear nights (triggering anthocyanin production for reds and purples)
The 2026 forecast is cautiously positive for the Northeast after a summer that was drier than average in Vermont and New Hampshire. The West - particularly Colorado - had a notably warm summer, which may slightly reduce peak intensity there.
