Day temperatures run anywhere from the mid-70's to the mid 90's Fahrenheit. There is always the benefit of refreshing sea breezes, which keep the whole island comfortable, no matter how hot the sun gets. Nighttime breezes cool the air to the crispy 60's - perfect to throw on a light sweater and go for a moonlit stroll. Summertime is indeed magical to Eastporters. The winters here are not as hard as those experienced inland, but they are long.
Spring is always very welcome, but short.
Autumn in Eastport is divine, and those who summer here are pained to leave as autumn begins - not because summertime has faded, but because they don't want to miss the second best season of the year. It was a booming fishing and sardine factory town. These buildings still stand today and are listed on the National Historic Register. To F.D.R. Tiny Eastport had presidential ties as well. Franklin D. Roosevelt had a summer cottage on Campobello Island, which sits just east of Eastport in the Passamaquoddy Bay.
