State of Maine Climate

Maine is a state located in the north-east of the United States, in the northernmost part of the country. Maine shares a border with two Canadian provinces of New Brusweck and Quebec.

Maine has one of the most stimulating climates in America. In fact, the state's favorable climate is a huge asset as it favors a productive work environment and it is a key factor in the state's tourism industry. The four-season vacation is a tourist magnet and a good source of revenue for the State.


There are three climatological divisions in Maine with distinct weather patterns, that is Northern Interior, Southern Interior, and Coastal.

The Coastal division stretches for approximately twenty miles inland along the coast. Because this section is tempered by the ocean, temperatures tend to be lower in summer and higher in winter than are normal for interior areas. Of course, it's more rainy here than the rest of the regions.

The Northern interior division makes up almost 60 percent of the entire land area of Maine. The climate in this division is mainly continental. This division has the highest elevations and it is the most distant from the ocean. The Northern Interior is the area that lays directly between the Canadian provinces of Quebec and New Brusweck, hence the similar climatic conditions with places in southern Canada. It's a sparsely populated region and is characterized by woods, mountains, and lakes.

The Southern Interior division stretches along the southern part of the state in a longitudinal belt, occupying about 30 percent of the state's total area. Spring in this region normally starts a month later than the standard calendar date of the start of spring. Warmer temperatures are felt from May and this is when the trees regain their leaves.


The summer climate of the state of Maine is one of the most comfortable among continental States in America. During the month of July, peak temperatures typically average at 70F in the entire state while temperatures may reach 90F in the Southern Interior division during very warm summers. This lasts for 25 days on average and 2 to 7 days in the Costal division. Summer nights are generally cool and winters are cold, although long cold spells are a rare occurrence.

Annual subzero temperatures may be as many as 60 days as recorded by weather stations in the Northern Interior division while the coastal division records up to 20 days a year of sub-zero temperatures.


The average annual precipitation of the state of Maine usually doesn't exceed 46 inches. For the Northern Division, it averages 40 inches while the Southern division averages 42 inches. The coastal division usually records the highest levels at 46 inches. Annually, there are about 10 to 20 thunderstorms that occur in Maine's coastal division while 15 to 30 occur in other areas. Hurricanes, ice storms and tornadoes are rare though.

Low-lying areas in Maine's inland often experience heavy ground fogs but the coastal areas get these fogs more frequently.

The southern division experiences approximately 80 to 120 fog-free days per year while northern regions have slightly fewer clear days without precipitation and fog. Portland has a 60 percent chance of sunshine while Eastport has 50 percent chances.

Snowfall in the Coastal division averages around 50 to 70 inches while the southern interior gets between 60 and 90 inches annually. The northern interior is generally colder with average snowfall of 90 to 100 inches annually.

Usually, there are not more than 20 days of snowfall of more than one inch in the coastal division in a year although there might be a 'Northeaster' of 10 inches or more in one day. Predictably, there might be more than 30 days a year of snowfall of not less than an inch in the Northern interior. Typically, January is the coldest month, recording up to 20 inches of snow sometimes.

Best Time To Visit Maine

Tourists flock to Maine at any time of the year, although the majority come during the comfortable summer weather. However, what you plan to do on your vacation will dictate the best time to visit.

There is a unique vacation opportunity during each of the four seasons. Moreover, the three regions offer plenty of things to do regardless of climate or time of the year. For instance, winter is the best time to visit if you're planning a ski vacation but summer is the best for a windjammer cruise.


Many ski resorts in Maine extend the skiing season weeks into spring because of the chilly months of March and April. Spring is also a great time for fishing and lots of other exciting outdoors.

Many visitors say that late spring is the best time to visit Maine when pre-season guests are greeted with huge discounts on almost everything.


Undoubtedly, most tourists affirm that the best time to visit Maine is summer. Obviously, it's easy to see why, given the beautiful warm weather. There's usually a lot of sunshine in summer and most tourist attractions are normally crowded during this time.

In particular, the warmest time starts from late June to September and this is when beaches on Maine's coast are irresistible. This is the most event-filled time of the year in Maine and one that's most recommended to plan a trip.


For couples without children, fall is a good time to tour Maine. It's when the huge crowds of summer start to disperse and once it gets to mid-September, you can begin to feel the peace and tranquility of the various tourist attractions in Maine.

Temperatures start to really drop around October and tree leaves start to change color around the same time. Fall foliage is a big attraction but the peak time varies, depending on the weather of the particular area of Maine you want to visit.

Then finally, winter is another special time in Maine, and although it can be brutally cold some years, it is the best time to visit Maine for some people. Predictably, skiing, ice skating, snowboarding, and winter hiking, among others, are the biggest activities that attract visitors.
