Fall Foliage Map 2026

The Science of Fall Color

Two primary factors control the timing of fall foliage: daylight and temperature. This means that the further north and the higher in elevation a tree is, the earlier it will reveal its colorful canopy. Photosynthesis grinds to a halt when the days grow short in the fall, and leaves no longer have a need for their excess stores of chlorophyll.

Over the course of a month or two, the concentrations of chlorophyll diminish, allowing less dominant chemicals such as anthocyanin and carotenoids to shine through, turning the leaf red, yellow, or orange. The rate at which this change occurs varies amongst tree species, so it can be difficult to pinpoint a single peak in fall foliage.

Nevertheless, when the vast majority of trees in a particular area have full canopies of autumnal color, peak has arrived. Some areas, particularly in the Northeast, experience vibrant red peaks due to an abundance of maple trees, while others experience a mixture of all of fall's colors. Different trees display different colors, giving each region its own unique peak.

When Does Peak Arrive?

For most of the United States, peak fall color arrives in the month of October. This is when wide swaths of the Northeast, Midwest, and Western states are aglow with bright fall foliage, and more than 80% of travelers make their fall foliage trips. Some less-populated regions will peak in September, while the southernmost states hold off until mid-November.

The most popular fall foliage displays are found in New England, where approximately ten million people travel each year in hopes of photographing or simply walking through fall's splendor. Northern Vermont, New Hampshire, and northwestern Maine experience peak in early October, while much of New York, Massachusetts, and Pennsylvania have to wait until later in the month.

Out west, golden aspens peak in sweeping displays in late September and early October, just prior to the invasive chill of winter. Non-desert, lower elevations in the Northwest are further delayed into late October or early November; however, the wait is well worth it.

Planning a Fall Trip

If you've ever traveled in search of fall foliage before, you likely know how tricky it can be to be in the right place at the right time. The timing of peak color varies significantly season-to-season, meaning what worked one year might not work the next. The best fall trips take careful planning, a lot of patience, and a reliable fall foliage map.

It's helpful to establish a baseline for when leaves normally change. Maps can help you identify roughly when in the season you should be planning your trip. From there, consult a real-time fall foliage map like ours to see if fall foliage is on-time or running early or late due to ongoing weather conditions.

If at all possible, don't solidify your plans until you're two weeks out from peak fall foliage. This allows you to be flexible should extreme weather disrupt the normal progression of fall foliage. If that is not an option, do your planning in early September when fall foliage experts can give you an idea of whether or not fall color is on-time this year.

You'll want to make the most of your time in fall's splendor, so be sure to pick out a few beautiful hikes or drives where you can truly be immersed in autumnal color. If you're looking to beat the crowds, consider visiting popular locations very early in the morning, before the majority of people arrive.
