What will the weather be like in Peru in December?
http://www.bbc.co.uk/weather/world/count… Such unusual and unexpected heavy rain may cause widespread damage. At the same time the sea temperature offshore rises and the cold current retreats southwards. The phenomenon is called El Niño, and is most likely to occur in December and January. This otherwise arid coastal strip experiences frequent low cloud and fog from which a light drizzle, called locally garúa, may fall. This is another unusual feature for such a dry climate. The climatic table for Lima is representative of the climate of the coastal district although the city is a short distance inland. Midday temperatures are here a little higher than on the coast. Lima has an average of only one to two hours of sunshine a day in the low-sun period, but this rises to between five to seven hours a day during the warmer months of December to April.
