Chile can be visited all year around, as it is a very long country with many different regional weather patterns.
Santiago and central Chile are best from October to March (the warm summer months), but the Lake District is also lovely in spring and autumn, and offers winter sports in July and August.
Patagonia is best visited from November to February, but being so far south the weather is changeable and most facilities are closed from June to August.
The Atacama Desert can be visited all year round, although the summer heat can be very intense from January to March.
Easter Island can also be visited all year round, with December to March being the most pleasant months. The Tapati Rapa Nui cultural festival occurs in February.
