Weather in May

May sees temperatures on the warmer side in Maine as the nightly lows rise above the freezing point. Throughout the state, the average temperatures are 37°F (2.8°C) to 65°F (18.3°C), as the cold and rain decrease substantially.
Snowfall is almost nonexistent by May except a few places on the mountaintops. Rain registers 3" (76mm) in many parts of the state, but the sun has to break the persistent cloud cover to average 8 hours of daily sunshine.
Brunswick, on the coast, has warm temperatures in the 45°F (7.2°C) to 65°F (18.3°C) range, while Bangor in Central Maine is slightly lower between 42°F (5.6°C) to 64°F (17.8°C). Even Fort Kent, which is usually one of the coldest places in the north, registers a comfortable average high temperature of 61°F (16.1°C).
Tourists enjoy Maine visits in May as the crowds are less compared to the summer and there are many discounts on hotels! Be sure to wear layered clothing and carry an umbrella or raincoat for protection from the rain.
