Climate in Peru
Peru has three climate zones, one of which governs the coastal region. Its desert landscape is caused by the cold Humboldt Current, which prevents cloud formation over the land. Lima is generally sunny and humid, with next to no rainfall, though it experiences heavy sea mists from April to November. The northern coast has hot, sunny summers, with occasional rain showers. The coast gets less arid farther north, as the effect of the Humboldt Current decreases. The Andes region is cool, and its wet season runs from October to April. The dry season lasts from May to October, and this is the most popular time to visit Peru. During the dry season, days in the highlands are clear and sunny, though nights become very cold, especially at altitude. The forested region of the Amazon Basin has an equatorial climate, where conditions involve hot weather and frequent rain throughout the year.
The best time to visit Peru is during the dry season, from May to October, and July and August are the peak months. Visitors will notice more rain between November and April, particularly over January and February. Travel at this time does offer the advantage of fewer visitors, greener scenery, and lower rates for flights and hotels. The Amazon also experiences more rain between November and March, but this should not deter you from visiting - the flora and fauna will still be abundant and there are always breaks in showers.
