Chile: When to Go
Chile's seasons are the reverse of the northern hemisphere, so go in the northern hemisphere winter for Chile's summer. However, be warned that mid-December to the end of February is also Chile's peak holiday season, so prices increase and accommodation gets booked up in advance.
The Atacama Desert is hot all year round, though the northern altiplano tends to see afternoon rain in the summer months.
Santiago and the Central Valley have an almost European climate, with warm, dry summers (November-April) and cool, wet winters (May-August). Go in spring (September-November) for the most verdant landscapes, or during the grape harvest (late February into April). Visit from June to August for skiing.
The Lake District is best from December to mid-March, when the sun is more likely to shine (although rain is still common) and temperatures are higher. Go in November/early December or March to avoid the main holiday crowds and the horseflies. Out of season many facilities are closed, although winter sports are increasingly featuring in the area.
The island of Chiloé has its own climate (rain for much of the year!). If you can, visit in February/March, when many towns and villages celebrate their annual fiestas and visitors can enjoy traditional foods like curanto, plus various sporting events and dancing.
Patagonia is best from December to March. The area south of Puerto Montt, including the Torres del Paine, has extreme winters, so avoid June-August. Spring is spectacular, as the mountains re-emerge from the winter freeze and the hillsides are ablaze with wildflowers.
