When do the leaves change in Connecticut?
Sugar maples and oaks blaze across the rolling hills of the Litchfield Hills and the Quiet Corner, with Route 169 and Kent Falls State Park drawing leaf-peepers as color peaks in mid-to-late October.
Peak: October 20–October 24
Color builds from October 7 · mostly bare by November 13
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.
