What is the best time to visit Edmundston?
July and August offer the warmest, most reliable weather for hiking and cycling along the Madawaska River, with daytime highs averaging 23–26°C.

Summer calls for light layers and rain gear; afternoon thunderstorms are common. For the shoulder seasons, a waterproof jacket and fleece are essential, as the Canada weather hub shows rapid temperature swings.
