Central Chile and Santiago – These areas enjoy a “Mediterranean” climate with four well-defined seasons and comfortable temperatures. Although year-round destinations, the best times to visit are between October and March when temperatures are warmer and rainfall is lower. The rainy season starts in April, peaking during June and July. March is a great time to visit the wine regions when the grapes are being harvested and wine festivals are held. In April the leaves display their autumn colours.
Northern Chile and the Atacama Desert
The desert areas are best avoided in the summer months when temperatures can be intense during the day, yet cold at night. Winters bring consistent blue skies for the entire region. It rarely rains, but when it does (most likely between September and March) the region breaks out in a spectacular bloom.
Lake District and Northern Patagonia
If you are heading to this region to ski, then the optimum months are June to August although the ski fields and ski resorts generally open from May to October. For other outdoor activities such as trekking, then the summer months of December to March are the best times to visit in terms of warmer temperatures. Spring (October, November and early December) is also a pleasant time to visit.
Patagonia is best visited in the summer months of October to March. Although some areas remain open year round, the range of activities is much more limited during the winter. There is no ‘dry season’ as such in Patagonia. Expect moderate rainy weather, high winds, and average temperatures of 10 to 18°C during the summer.
Easter Island has a subtropical climate and can be visited year-round. The average maximum summer (Dec-Mar) temperature is 28°C. The average winter minimum is 14°C, but winds can make it feel colder. Rain can fall at any time of year, but May tends to be the wettest month. The busiest months are the summer months, so if you want to avoid the crowds, then winter is highly recommended. Winter is also the best time for hiking on Easter Island.
