Nights are often cool , so take a sweater. Winter-like nights can begin in late October in the interior and north but snow is rare before late November. Some attractions close for the winter .
Spring can be cool and wet.
We recommend visiting New Brunswick from mid May through mid October . Though the leaf season is not as well known as that of New England, it is just as pretty, and there are no crowds. Plan to go between mid September and mid October for the top color.
