Chile's mountainous geography spanning over 30° of latitude makes for some strange climatic variation. Summer and winter in Chile's north are quite restrained with temperatures in the 15-25°C (63-77°F) range throughout the year with only slight seasonal change. Rain is of no concern as this coast-to-desert landscape is one of the driest in the world, despite heavy cloud cover from April to December. Central Chile has far more pronounced seasonal change with average daily highs of 29°C (85°F) from December to February and dropping to around 14°C (58°F) in June. Rainfall is heaviest in the winter months but still only moderate and falling on a few days at this time. Down south rainfall increases dramatically, peaking in June with most days succumbing to the wet. Temperatures in this region are slightly cooler with low 20°C (around 70°F) summer highs and plunging into the single digits (around 42°F) in the middle of the year.
