October is Maine’s busiest fall month. Foliage moves south through the state, the weather turns crisp, and the fairs and harvest events are in full swing, while many summer businesses begin to wind down. Here is what to expect, with weather figures from the National Weather Service.

What Is the Weather Like in Maine in October?
Using the National Weather Service’s 1991-2020 normals for Portland, daytime highs fall from about 65°F on October 1 to 59°F by mid-month and 54°F by October 31. Overnight lows drop from about 46°F to 41°F to 36°F over the same stretch. Portland averages roughly 5 inches of rain in October and only a trace of snow (about 0.2 inch on average).
Inland, higher elevations, and northern Maine run colder than the coast, and frost is common. Pack layers, a warm hat, and a rain jacket, and plan for the temperature to feel lower on the water and on summits.
When Is Fall Foliage Peak in Maine in October?
Color usually peaks first in northern and western Maine and at higher elevations, then moves south and toward the coast through the month. Exact timing changes every year with temperature and rainfall, so check our Maine fall foliage guide and the foliage timing tracker, which shows the expected peak for each region. For specific places, see fall foliage in Bar Harbor and our best fall foliage drives.
How Crowded Is Maine in October?
Very, on peak weekends. The Columbus Day weekend (called Indigenous Peoples’ Day in Maine, the second Monday of October) is one of the busiest of the year, especially in Acadia and the popular coastal towns. Book lodging and restaurant tables well ahead for that weekend, and consider weekdays or the days just before or after if you can. Our guide to the best time to visit Maine compares the seasons.
Fairs, Festivals, and Events in October
The big one is the Fryeburg Fair, which runs about a week in early October (October 3-11 in 2026). The Cumberland Fair also runs into the first days of October. Harvest festivals, Halloween events, and fall markets fill the rest of the month. See our Maine events calendar for current dates and official links.
What Is Open and What Closes in October?
Many seasonal businesses, tours, and some restaurants cut back or close after the Columbus Day weekend, especially in coastal and resort towns, so call ahead. At Acadia, the Island Explorer shuttle typically stops running in mid-October. Some state park campgrounds are winding down for the season, so check our guide to state park camping reservations and the park’s season dates. If you plan to hike Katahdin, check the Katahdin Trailhead Pass rules first.
