@Stephanie I'll answer with a visual from my performance page:
Maine is said to have 6 seasons: Mud Season, Spring, Black Fly Season, Tourist Season, Fall, and Salt Season.
Tourist Season officially kicks off on the 4th of July and officially ends in early September on Labor Day.
July and August are so idyllic in Maine that my daughters and I often refer to it as Camelot, from the song in the musical: "A law was made a distant moon ago here/July and August cannot be too hot/The rain may never fall till after sundown/By eight, the morning fog must disappear/In short, there's simply not/A more congenial spot/For happily ever aftering than here in Camelot."
