What is the best time to visit Peru weather wise?
That depends on where you plan on visiting. There are three main zones of Peru: the coast (La Costa), the mountains (La Sierra) and the jungle (La Selva). If you are visiting the coastal desert area, which includes Lima, then it is better to come during Peru’s summer months, December-March. Once you enter the mountains or the jungle there are two seasons: wet and dry. If you are planning on visiting La Sierra which includes such tourist spots as: Cusco, the Sacred Valley, Machu Picchu, and the Inca Trail you should come during the dry season which runs from May-September. The best time to visit the jungle is also during the dry months of May-October.
