Saint John's weather can be slightly cooler than other parts of New Brunswick due to its coastal location. The proximity to the Bay of Fundy and the North Atlantic Ocean can influence the temperature, causing maritime air to have a moderating effect. This means that Saint John may experience milder summers and cooler winters compared to inland areas of the province.
