This Map Will Tell You When Your State Will Hit Peak Fall Foliage

"SmokyMountains.com is here to help with its annual Fall Foliage Map. The map uses an algorithm developed from tons of data — like historical temperatures and forecast precipitation from the National Oceanic and Atmospheric Administration — to create a predictive map of when trees will reach peak viewing status around the country. The algorithm then produces a county-by-county breakdown of when colorful leaves are expected to peak that you can toggle through week-by-week. "Similar to any meteorological forecast, leaf predictions will never be 100% accurate," company founder and statistical expert David Angotti said in a statement shared with Travel + Leisure. "However, after publishing our predictive fall foliage map for nearly a decade, we are quite confident in our data sources, process, and algorithm." - Travel + Leisure Editors
