Season notes from our guide
The dry season, May to September, is the main season, with clear mornings and stable weather. Nights are very cold: -10 °C or lower at camp in June and July, and water bottles freeze. April and October are quieter, with more cloud and the odd snow shower. From November to March it is the rainy season: daily rain and snow on the passes, slippery paths and fog. Snow can cover the passes in any month. Around late May or early June the Qoyllur Rit'i pilgrimage near Ocongate fills the buses from Cusco.
