The barometric pressure in Montreal, Quebec, Canada is typically between 980 and 1030 millibars. This range is considered normal. Pressure changes can indicate weather shifts.

Montreal is surrounded by the Saint Lawrence River to the south and the Laurentian Mountains to the north. The river brings moisture from the Atlantic Ocean. The mountains block cold air from the Arctic.

The mountains also create a phenomenon called the "Saint Lawrence River Valley Effect." This effect traps cold air in the valley during winter. It keeps warm air from the Gulf of Mexico from reaching the city.

In summer, the mountains block hot air from the south. The Saint Lawrence River cools the city by 2-3°C compared to inland areas. This results in a more moderate climate.
