With the official start of autumn arriving on September 22, anticipation is building for the annual transformation of leaves across the United States. While most regions are expected to experience peak foliage between late September and mid-October, the exact timing and intensity of the colors remain subject to local weather conditions leading up to the season.
Meteorologists at AccuWeather suggest that the most promising viewing opportunities for 2026 will likely occur across the Great Lakes region, the upper Midwest, northern Pennsylvania, northern New York, and northern New England. These areas, particularly within the interior Northeast, largely avoided the severe drought conditions that impacted other parts of the country during the summer months.
In New England, the outlook is particularly positive. According to foliage expert Jim Salge of Yankee magazine, forests in the region have benefited from a cold, snowy winter, sufficient spring moisture, and timely summer rainfall. This has allowed trees to enter the late summer season with healthy, lush canopies and minimal insect or fungal damage. Salge notes that 2026 could offer a distinct experience from the previous year, with colors potentially arriving more gradually and lingering longer as the change moves from northern mountains toward the southern coast. He describes the current outlook as a potential setup for a long, spectacular foliage season.
Conversely, drought remains a significant concern for color quality in other regions. Long-term moisture deficits can stress trees, which is often detrimental to vibrant displays. Consequently, experts anticipate duller conditions across portions of the Southeast, including the Carolinas and Georgia, as well as throughout parts of the Rockies where drought conditions remain severe to extreme.
The timing of the foliage shift is also influenced by temperature and weather volatility. Meteorologist Brian Lada notes that trees already under stress may shed their leaves earlier than usual, a trend that could affect areas from Georgia to New Jersey and across the Rockies. Additionally, late-summer tropical systems or strong windstorms pose a risk, as high winds can strip leaves from branches prematurely, cutting the viewing season short.
Temperature variations are expected to create localized delays. Warmer-than-average days in the Ohio and Mississippi Valleys may push the onset of leaf drop back by approximately two weeks, while similar conditions in the Northwest could delay the change by about a week. Outside of these specific regions, peak foliage is generally expected to arrive on a standard schedule across the Northeast, the Great Lakes, and the northern Plains.
Long-term environmental shifts are also playing a role in the timing of the season. Amanda Gallinat, an assistant professor of environmental studies at Colby College, points to historical records and satellite observations indicating that peak foliage is trending later in the year due to warming temperatures associated with climate change. In New England, for instance, the peak of the season now occurs about a week later on average than it did during the 1950s. The report also notes that maps show when and where to see the best colors in fall 2026. The report also notes that as the first day of fall approaches on Sept. The report also notes that 22, attention turns to the vibrant and gorgeous colors that leaves will soon be sporting. The report also notes that indeed, leaf-peeping season is almost here as the scorching heat of summer comes to a merciful close. The report also notes that an AccuWeather map shows how fall colors will peak in September in the North and move south as fall continues. The report also notes that the result, Salge says, could be a very different season from 2025, with color arriving more gradually and lingering longer as it moves from the northern mountains to the southern New England coast. The report also notes that “Our early call for 2026: A slow start could set the stage for a long, spectacular foliage season,” Salge said in an e-mail to.
