The United States is currently experiencing the peak of its fall foliage season, a time when the leaves of deciduous trees transform into a stunning array of reds, oranges, and yellows. This natural spectacle is driven by decreasing daylight and cooler temperatures, which cause trees to cease chlorophyll production, revealing underlying pigments. The timing of peak foliage varies geographically, with northern states typically reaching their peak earlier in the season (late September to mid-October), followed by central states (mid-October to late October), and finally southern states (late October to early November).
