Typically, northern Maine (zones 6 and 7) reaches peak conditions the last week of September into the first week of October. The rest of the state’s progression of color will start occurring from north to south in mid-October. Coastal Maine typically reaches peak conditions mid-to-late October.
“We have had summer-like weather leading up to the beginning of the fall foliage season; however, we’re still on track for a typical season. As our weather takes a more seasonal turn, colors will start moving toward peak conditions in early to mid-October,” according to Gale Ross, fall foliage spokesperson.
