Santiago Weather Guide

Famous for its warm, dry summers and infamous for its smoggy winters, choose your travel time carefully to make the most of Santiago's seasons. The ski season lasts from July to September, while summer in the city is pleasant and usually considered the best time to travel to the Chilean capital.

Season and Clothing

Summer: November to March

With a Mediterranean climate, summers in Santiago are typically long, warm and dry with temperatures typically falling around 19 degrees Celsius during the day. However, during this time locals tend to leave the city to enjoy their  holidays elsewhere, and as a result, accommodation prices drop in summer, offering not only ideal weather but cheaper prices too. If timing isn't an issue, summer is commonly regarded as the best time to visit Santiago. New Year's Eve sees one of the biggest fiestas on the calendar with fireworks and dancing 'til all hours. Don't miss the annual Grape Harvest Festival held in February in Curico, just outside Santiago in the winemaking districts, or the International Arts and Crafts Festival in November.

Average temperatures: 13 - 25 degrees Celsius.
Appropriate clothing: Summer clothes, bathing suit and sandals.
Don't forget: Sunscreen, sunglasses and a hat.

Autumn: April to May

Autumn in Santiago is a quick transition season from summer into winter when temperatures decrease gradually and the rainy season begins. If you don't mind getting a little wet, autumn is still a great time to visit Santiago before the smog and humidity of winter hits. The cooler conditions also provide the ideal weather for the annual Santiago Marathon in April, which takes in heaps of the city's famous sites starting and ending at Palacio de la Moneda and taking in Parque O'Higgins and around the base of San Cristóbal Hill. Not feeling quite up to running 42 kilometres? Lollapalooza Chile may be more your speed. The offshoot of the famous US music festival takes place in Parque O'Higgins in April with heaps of international and local headliners.

Average temperatures: 11 - 14 degrees Celsius.
Appropriate clothing: Light layers and comfortable walking shoes.
Don't forget: A raincoat or umbrella.

Winter: June to August

Winters in Santiago are infamous for their humidity, rain and smog. Still, in the rainy season, winter temperatures typically drop as low as 8 degrees Celsius, but witness high humidity. Mornings during the season are particularly cold and foggy, so don't bother venturing up to San Cristóbal Hill too early as the view may be obscured. Instead, the best place to spend winter in Santiago is on the nearby ski fields at Valle Nevado. If you are hanging around the city, head indoors to check out a range of local and international flicks at the annual Santiago International Film Festival (SANFIC) in August.

Average temperatures: 4 - 15 degrees Celsius.
Appropriate clothing: Clothes for layering, a waterproof coat and comfortable boots.
Don't forget: A raincoat, scarf, gloves and ski gear.

Spring: September to October

Spring in Santiago brings mild weather and lifts the all-encompassing smog from the city to reveal a colourful season of flowers and green foliage. During this time, Santiago is also a hive of activity with a number of events taking place including the 2-day festival of Fiestas Patrias in celebration of Chile's first government and subsequent independence in 1810. There's traditional music, food, dancing and parades with colourful costumes and Criollo horses in the street and military parades around the main square. On October 12, Columbus Day is celebrated with more food, drink, dancing and festivities around Santiago.

Average temperatures: 11 - 14 degrees Celsius.
Appropriate clothing: Clothes for layering, a coat and comfortable walking shoes.
Don't forget: A camera and your dancing shoes.
