The barometric pressure in Santiago, Chile, varies throughout the year due to the changing seasons. During the summer (December to February), the city experiences lower pressure, often accompanied by warmer temperatures. In the winter (June to August), the pressure is higher, bringing cooler temperatures and the possibility of rain or snow.
The landscape surrounding Santiago, with the Andes Mountains to the east and the Coastal Range to the west, greatly influences the atmospheric pressure. The mountains act as a barrier against weather systems, causing Santiago to have a semi-arid climate. This results in lower humidity and less cloud cover, contributing to the fluctuations in barometric pressure seen in the city.
