Santiago has a Mediterranean climate with dry summers and mild, wet winters. This climate type brings high pressure in summer and low pressure in winter.
High pressure in summer means clear skies and dry air, perfect for outdoor activities.
Summer air pressure is also affected by the Andes Mountains, which block moist air from the Pacific Ocean.
This creates a rain shadow effect, making Santiago's summers very dry.
In winter, low pressure brings rain and cloudy skies, making it perfect for indoor activities.
The Andes Mountains also push cold air from Antarctica towards Santiago, making winters chilly.
