August is historically Churchill’s wettest month, with about 60 millimetres of rainfall, according to climate data. The community’s location on the western shore of Hudson Bay often leads to foggy conditions in the summer, as warm air passes over the cooler bay waters.
Churchill has a subarctic climate, with short, cool summers. Even in a normal August, the average daily temperature is around 15°C. The below‐normal temperatures this week mean outdoor plans may be less comfortable, and residents should be prepared for damp, cool weather that’s more suited to indoor activities.
