Soon the days will grow crisp, and the days are already growing shorter, Granite City residents are watching the treetops for signs of autumn’s arrival. This year’s fall foliage forecast suggests a slightly delayed but vivid season, with peak color expected in late October across Madison County.

According to the Illinois Fall Foliage Map, leaves in southern and southwestern Illinois. including Granite City will begin changing in early October, reaching their most brilliant hues by the last week of the month. The shift is slower than usual due to lingering warmth, but cooler nights in late September should kickstart the transformation.

Early October: Subtle changes begin.
Mid-October: Color intensifies, especially in maples and oaks.
Late October: Peak viewing window.
Early November: Foliage fades, with many trees bare by mid-month.

Oaks: Deep russet and golden brown.
Hickories and sycamores: Warm yellows and amber tones.
