Late September and early October tend to showcase the best colours,
but the timing will vary by region.
There’s a north/south variation, with the northern areas
(Appalachian Mountains, upper Saint John River Valley, Miramichi region)
producing colour one to two weeks before the south (Bay of Fundy,
lower Saint John River Valley, parts of the Acadian coast).

The colour is also affected by variations in topography,
and where specific trees grow along the landscape.
For most of the year these differences are subtle,
not even noticeable to most, but come fall it makes for a
veritable ice cream sundae of colour.
