Weather in September

September starts the beautiful autumn season with the average high temperatures around the 70°F (21.1°C) mark. While the day temperatures rarely touch 80°F (26.7°C), the nights are in 45°F (7.2°C) to 50°F (10°C) range.
Rain does not fall short of expectations and is to the tune of 4" (102mm), so it is always advisable to have some rain protection. Thunderstorms are not entirely unknown, bring rain, and a drop in temperatures.
However, the weather is usually perfect for walking, biking, kayaking, and other activities. Northern Maine has many mountain trails, and the fall season is ideal for exploring them. Visitors gather from all over the country to witness the fall foliage, which is spectacular and surpasses almost all the places in the country. The hunting season is in full swing in September, so be sure to wear colorful clothing that is visible from long distances, such as blazing orange to avoid any misadventure!
