Peak fall color is predicted around October 14. Plan for the strongest viewing window from October 9 to October 19.

Confidence range±5 days
The prediction is a 24-year climatology built from NASA MODIS MOD13Q1 vegetation-index data, with the definition of peak calibrated against PhenoCam ground cameras. Where state foliage spotters report peak (New York, Pennsylvania, Wisconsin and Missouri), it has landed inside our ±5-day window about two years in three. An unusual summer or autumn can still move it further.
