When Are Fall Colours at Their Best?
Late September and early October are useful dates to consider when planning a foliage-focused visit to the Edmundston region.
However, peak colour is not fixed. It varies with temperature, rainfall, wind, elevation, and the timing of the season.

5. Shoulder Seasons: Balancing Weather, Crowds, and Costs
The periods around late May to early June and September to mid-October can offer an appealing balance between outdoor activities and a more relaxed atmosphere.
They are particularly useful for travellers who have flexible dates and do not need the warmest possible weather.
