Our Climate

Summer temperatures are generally quite comfortable, with afternoon temperatures in the upper 70s to low 80s. Summer evenings are generally cool, with many readings in the low 60s. Early and late average summertime highs are in the mid 70s. In mid-summer, highs hover around the 80 degree mark.

The fall foliage season brings a lot of leaf-peepers to Maine. The peak season falls between the end of September and mid-October.

Typical winter weather is cold across the Bangor region with average high temps in the mid to upper 20s during January, but climbing to the low to mid 30s by late February. Winter temperatures frequently drop into the single digits with some nighttime lows dropping below zero most years. By April, temperatures reach into the mid 50s and inch up toward 70 in May.

Seasonal snowfall is subject to wide variations from average, from only 32.5 inches in 1952-1953 to 181.9 inches in 1962-1963. The number of snowfalls of one-inch or more in a day, average 23 per season. The average seasonal maximum snow depth is 25 inches, occurring in the second week of February, on average. To compare a few recent winters, in 2010-11 and 2014-15 there were six storms of 10 inches or more of snow.  Blizzards are not uncommon in Maine and we did have a few blizzards in 2014-15 that dropped 18 in. of snow. The typically large storms are nor’easters.

Precipitation is relatively abundant and dependable. There are no “rainy” or “dry” seasons, though summer totals are usually less than in the winter. It generally doesn’t get muggy in Maine.

In summary, the Bangor region is nearly free of extreme or very uncomfortable summer heat, and nights are generally comfortably cool, even on the hottest days. With clear skies, the night to day range in temperature is frequently more than 30 degrees, especially in spring and early summer. This fluctuation allows for comfortable days and cozy nights.
