"In general, we are seeing fall foliage is occurring later than it has historically, based on global climate change," Kosiba says. Peak foliage usually lasts seven to 10 days, according to Almanac, though weather conditions can make a big difference. "My thought personally, because I love the fall foliage season, is that it's always good somewhere," she says. Wetlands can be a great place to look for fall foliage, especially for deep reds.
