The weather in May
The official climate normals for the Machu Picchu station (SENAMHI, 1991–2020) give May an average high of 22 °C, an average low of 11 °C and 73 mm of rain over the month. It is dry season: clear mornings, strong sun by midday, cold nights in the Sacred Valley and Cusco, and the best visibility of the year from the platforms and the summits.
Crowds, capacity and holidays in May
Demand is moderate: well below the June-to-August peak, with busy pockets around holidays. Most routes are available a few weeks ahead; Huayna Picchu still goes first. Dry weather without the high-season capacity or crowds: the Ministry's high season does not start until 19 June. 1 May is a public holiday; Cusco's Corpus Christi falls on 27 May in 2027.
Which ticket to book in May
- Huayna Picchu or the Mountain, booked first: Clear skies make this the season for the summits: Huayna Picchu 3A (2,693 m, adults only) sells out first, Machu Picchu Mountain 1A (3,082 m) is the fallback with the bigger view. Both need two nights of acclimatisation first.
- Circuit 2A for the city: The designed route through the whole Inka city, 2 h 30. In these months it is the first city route to sell out; 2B covers almost the same ground and usually has dates when 2A is gone. 2A.
- Take the first or the last entry: At 06:00 the light is low and the platforms are half empty; by 10:00 the day-trippers from Cusco arrive. The afternoon entries after 13:00 on 1B, 2A, 2B and 3B are the quietest hours and the last to sell out.
Trains and getting there in May
The trains run the full May-to-December timetable: departures from Ollantaytambo all day on both PeruRail and Inca Rail, plus PeruRail's direct services from Poroy and San Pedro in Cusco. Standard seats from $62 one way; the entry sells out long before the train does, so book the entry first. Every class and fare is in the train guide.
What to pack for May
Layers: it is near freezing in Cusco before dawn and 22 °C on the terraces by noon. Hat, sunscreen and sunglasses, the sun is strong and there is almost no shade inside; a litre of water per person (bottles allowed, no single-use plastic); a light rain layer for the odd shower.
