When to see peak color at Castlewood State Park
Peak fall color is predicted around October 30. Plan for the strongest viewing window from October 25 to November 4.
- Predicted peak
- October 30
- Best window
- October 25 – November 4
- Confidence range
- ±5 days
The prediction comes from 14 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 Saint Louis County and across Missouri.
That is 5 days later than usual (October 26): the six weeks to October 21 ran 4.3°F warmer than the 2001–2025 average, and a warmer run before peak delays the color.
