Summers (December to February) in Santiago are sweltering. The city’s location in the middle of a valley means that pollution and humidity tend to settle over Santiago and temperatures can reach as high as 85 degrees Fahrenheit during the day. Though the sun can be brutal in the summer time, this is still the busiest time of year to book flights to Santiago. Winter months (June through September) are mild with some precipitation and average temperatures hovering around 52 degrees Fahrenheit.
Best Time to Fly to Santiago
Whether you’re eagerly anticipating a snowy ski holiday in the Andes or a sultry night of salsa dancing at a club in Bella Vista, there’s no wrong time to visit Santiago.
Santiago flights tend to fill up between the months of December and March, when visitors are flocking to Santiago for the holidays, and Santiago natives are heading out of the city to nearby Valparaíso in hopes of avoiding the scalding summer heat. Santiago is the capital of a predominantly Catholic country, so booking flights to Santiago during Holy Week and the Easter holidays should be made months in advance.
The transitional seasons of fall and spring are the best times for finding cheap flights to Santiago. Given that Santiago is located in the Southern Hemisphere, spring falls between the months of September and November, while fall takes place from April until mid-June. Those who find cheap flights to Santiago for a September trip are in luck, as the Semana de la Chilenidad – a festival celebrating all things Chilean with parades and performances – takes place in mid-September.
