Connecticut Fall Foliage Report Last Updated: August 2021

Connecticut’s fall foliage season is always stunning! The State of Connecticut Department of Energy & Environmental Protection (DEEP) interactive fall foliage report map is now available. It forecasts the progression of color across our corner of New England. According to current estimates, peak foliage arrives in the northeast and northwest corners of the state around Columbus Day and extends to the lower Connecticut River Valley and shoreline through early November.

Magnificent foliage season predicted for Connecticut

State foresters say this year's Connecticut's foliage season is filled with vibrant colors. Better yet, Connecticut’s foliage season typically runs longer compared to northern New England states, offering travelers even more opportunities to see and experience the autumn beauty.

According to Christopher Martin, Director/State Forester, Division of Forestry, Bureau of Natural Resources, DEEP, “This year will be way different than last. Certainly no drought. And although there were pockets of gypsy moth defoliation in western Connecticut, sufficient rains have allowed the trees to releaf with less stress. Leaves will stay green longer this season and if overnight temperatures cooperate, dipping into the low 30’s overnight a few times toward later September, we should expect everything to come together all at once. Synchronized for a dazzling foliar display mid to late October. Later September/early October overnight temperatures will be the most influencing factor this year."

Peak foliage timeframes

The leaves will change in the northern parts of the state first, around Columbus Day, and then move down into the valleys and down toward the shore. Here are estimated peak foliage timeframes for each section:

  • Connecticut Northwest/Northeast Corners: October 3 – 8
  • Connecticut Eastern and Western Mid-State Counties: October 16 - 23
  • Shoreline and lower Connecticut River Valley: October 24 - 30
  • Southwest Corner: November 7 - 14

A little known fact is that the Connecticut River, starting at the mouth of Long Island Sound (between Old Saybrook and Old Lyme) and going up toward East Haddam, will hold the foliage the longest – into the first week or so of November. If you're leaf-peeping later in the season, the southern parts of the state such as Fairfield county are the place to look.

The diverse range of destinations and attractions across the state provides hundreds of interesting and unique vantages from which to view the gorgeous foliage. From Mystic Seaport Museum’s harbor to a farm in the quiet countryside, from the top of Gillette Castle to the middle of a classic Connecticut corn maze, fall in Connecticut is not to be missed.
