St. John's weather is often stormy and windy due to its location near the Atlantic Ocean where cold Arctic air meets warm air from the Gulf Stream. This clash of air masses makes air pressure constantly change.
St. John's is surrounded by water on three sides, which affects air pressure, making it more unstable and prone to sudden changes. The city's unique geography, with hills and valleys, also impacts air pressure, creating microclimates.
In winter, cold air from the Arctic dominates, bringing low pressure and strong winds. In summer, warm air from the Gulf Stream takes over, bringing high pressure and calmer weather.
St. John's has a marine climate, which means air pressure is often influenced by the ocean's warmth. This leads to mild winters and cool summers, but also makes the weather quite unpredictable.
