Why Fall Foliage Colors Depend on Weather | Rochester News

Why do leaves turn fiery reds, yellows, and oranges in fall? It’s all about chlorophyll fading as days shorten, revealing hidden pigments like xanthophyll, carotene, and anthocyanin. Weather matters too—dry late summer and cool, frost-free fall temps boost color intensity. This year’s above-average September temps may delay frost, but spring’s heavy rains raise questions about whether too much moisture could dull the show. The official “I LOVE NY” Fall Foliage Report should drop mid-September for the real forecast. Keep watching the sky—and the trees—for nature’s next masterpiece.
