This spectacular Ancascocha trekking route is located in the outlaying area of Cusco, part of the Peruvian Andes mountains. So the type of weather you can expected on the Ancascocha trek and some other similar alternative trails leading to Machu Picchu have the same kind of climates as in the whole region of Cusco, divided into two different seasons: dry and wet, from May to October is considered the dry season with a minimum chance of getting rainy days, mainly sunny and hot during the day. But cold at night especially in winter time(June – August). From November to April is the rainy season, usually heavy rain falls, thunder storms, cloudy and at this time you will have less visibility on the mountains in the whole Andes, definitely not the best time to go trekking on the Mountains.
For Ancascocha trek to Machu Picchu and other trails we highly recommend hikers to bring a good four season sleeping bag or it could be hired here in Cusco, also a change of clothes for sunny days and cold temperatures at night time. The Ancascocha trail goes in the proximity of the cloud forest so the weather is usually warm and dry in the winter season, rainy and cloudy in the wet season, totally opposite to the northen hemisphere. But at Machu Picchu you can expect very changeable weather, sometimes unpredictable usually sunny days from June to August, cloudy and rainy days the rest of the months, a good rain gear is always advised to take with you.
If you are hiking the Ancascocha Trek to Machu Picchu a good winter clothing is required because you will have two cold nights at high altitude, also dry-fit clothes are highly advised and especially if you are planning to trek in the wet season (November to April).
