The prediction comes from 24 years of fall color records at this spot, checked against what observers on the ground saw. 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. Explore fall color around Orinda and across California.
Fall color at Tilden Regional Park begins as early as October 5 in some spots and continues through November 5 in others — a 31-day window where you can catch peak color somewhere in the area regardless of when you visit.
