When do the leaves change in Illinois?
Shawnee National Forest's Garden of the Gods and the bluffs of Starved Rock State Park turn oak-hickory and sugar maple gold, with peak color reaching most of Illinois by mid-to-late October.
Peak: October 27–November 2
Color builds from October 15 · mostly bare by November 21
Method: daily ERA5 temperatures (Open-Meteo) drive a photoperiod + chilling phenology model; terrain shifts timing ~1 day earlier per 300 m of elevation. Temperature alone can’t tell a maritime autumn from a continental one — two places at the same latitude and the same September can peak weeks apart, because the trees differ — so each region is also calibrated against published peak dates. Estimates, not promises: typically within a few days, occasionally a week or more out. Check locally before you travel.
