The coastal region of Peru is cool for its latitude, and quite dry year-round. Temperatures are warmest during the summer months (January to March), with hot and humid days of around 29°C (84°F) and cool nights of just below 20°C (68°F). Winters are not too cold, but frequent low cloud may cause some to pine for sunshine. Inland, the temperature drops substantially, with less seasonal variation during the day - average highs are about 21°C (70°F) throughout the year and winter nights are chilly, particularly at higher elevations. There is also a moderate wet season here from December until May.
