March weather forecast
Maine, USA

March in Maine is a transitional month, acting as a bridge between the harsh winter and the eagerly anticipated spring. As the month progresses, the state witnesses a gradual increase in temperatures. While nights can still be chilly, averaging 20°F (-6.7°C), daytime temperatures start to feel a bit more bearable, often reaching the lower 40s°F by month's end.

Coastal areas such as Portland and Camden experience slightly warmer temperatures, benefiting from the Atlantic's tempering presence. However, places inland and towards the north, like Lewiston and Houlton, take a bit longer to shake off winter's grip. Here, remnants of snow often persist, and fresh snowfall, while decreasing in frequency, is still possible.

In contrast to the colder months of January and February, March experiences a decline in snowfall amounts, but the presence of melting snow, occasional rain showers, and increased sunlight lends the landscape a wet and muddy character. This period is often colloquially termed as 'mud season' by locals.

Following February's footsteps, March continues the trend of longer daylight hours and more frequent sunny spells. While snowstorms are rarer, they are not completely out of the question, especially in the earlier parts of the month. As April approaches, the warming trend becomes more evident, with the state inching closer to the refreshing bloom of spring. Trees start to show budding leaves, and the first sprouts of green appear on the landscape.
