Summer (December to February) is the high season in Santiago, with warm and sunny weather and lots of outdoor activities. However, it’s also the busiest time of year, with lots of tourists and higher prices for accommodations and flights.
Fall (March to May) is a good time to visit if you want to avoid the crowds and enjoy cooler temperatures. The fall foliage can also be beautiful, especially in the parks and gardens around the city.
In Winter (June to August) Santiago can get quite cold in the winter, with temperatures dropping below freezing at night. However, it’s a good time to visit if you want to ski or snowboard in the nearby Andes mountains. They are only a short drive away.
Spring (September to November) is a good time to visit if you want to see the city’s parks and gardens in bloom. The weather is mild and pleasant, and there are fewer tourists than in the summer.
