September Weather in Maine: Hottest, Coldest, and Average Temperatures

Maine is known for its unpredictable weather. For example, it can be mild one minute and snowing the next. The climate also varies throughout the state, so it could rain along the coast, with blue skies further inland. September weather in Maine is crisp, with spectacular scarlet, orange, and yellow forests. Visiting the Pine Tree State in the fall won’t disappoint. While the weather is cooler, there is still plenty to keep you entertained.

Average September Weather in Maine

September is the most beautiful time to visit Maine. Once the cold sets in towards the end of the month, the leaves start to change, creating a kaleidoscope of colors. The western mountains and lakes are the best areas in the state to experience leaves changing color.

The maximum average September temperature in Maine is approximately 70 degrees Fahrenheit, while its minimum average is 49 degrees. The weather makes it perfect for activities like apple picking, hiking, or fishing.

You’ll want to wear the correct clothing when visiting Maine in September. Layering is always a good choice because of the fluctuations in temperature during the month. For example, pack long sleeve shirts, cozy sweaters, and fleece jackets. Some residents brave the cooler weather in their shorts, but because it’s Maine’s rainy season, layering, a raincoat, and an umbrella is the best choice.

The Pine Tree State is also susceptible to extreme temperatures in September. For example, Rangeley experienced a scorching 94-degree day on September 10, 2002. In contrast, Maine can also experience ice-cold weather during September, like in 1949, 1964, 1991, and 1994 when temperatures dropped to 41 degrees Fahrenheit.

Rainfall

Maine’s rainy season lasts most of the year, from March to December. September sees an average rainfall of 3.5 inches. However, the wettest month is June, which usually receives around 3.9 inches of rain.

Natural Disasters

Maine is no stranger to natural disasters, and unfortunately, the state has been hit quite a few times during the month of September. For example:

• The Great Atlantic Hurricane, a category two storm, hit Maine on September 15, 1944. As a result, apple crops were destroyed, and two people lost their lives.
• Hurricane Carol made landfall in the state, causing minor damage on September 7, 1953.

Visiting Maine in September

While many people visit Maine during spring and summer because of its warm and inviting weather, fall is much more beautiful. It may be a bit colder, but the scenery makes up for it. So, if you are looking to travel to the Pine Tree State out of season, September is an ideal time. There is still plenty to do, and you can experience activities visitors can’t during the summer. For example:

But, the fresh oysters are not the only attraction. Visitors can enjoy scenic boat tours, live music, and breathtaking riverside views.

Clients also have the choice of Kennebec River cruises, lighthouse visits, and sunset cocktail cruises.

Visitors may see several whale species while in Maine, as these giants return to the state to feed on copepods, sand eels, fish, and plankton.
