New Brunswick

While New Brunswick is a maritime province, bordered by the Gulf of Saint Lawrence to the east and the Bay of Fundy to the south, its climate is notably more severe than other, lower-lying maritime provinces with extensive temperate ocean coastlines. The reason for this is primarily due to the frigid air masses that sweep in from the continental interior, especially during winter. This creates a unique blend of coastal and inland weather patterns.

To truly experience the beauty and diversity of New Brunswick, it’s essential to understand these climatic nuances. Therefore, planning the best time to visit New Brunswick requires consideration of both the coastal influences and the inland cold, to best experience the province.

New Brunswick features a humid continental climate, characterized by harsh, snowy winters. In fact, snowfall is abundant, with regions typically receiving between 2 to 3 meters annually. During cold snaps, temperatures can plummet to -30°C or even lower.

This warm current, combined with shallow waters, creates ideal beach conditions, making New Brunswick a top beach destination in Canada.
