Best Time to Visit Machu Picchu

Machu Picchu sits in high cloud forest on the eastern slope of the Andes, so it has two seasons rather than four. The dry season runs roughly May through September: cold, crisp nights, strong sun by mid-morning, and little rain. The wet season runs roughly November through March: warmer, greener, and punctuated by afternoon showers that usually clear as quickly as they arrive.

April and October are the shoulder months, and they are quietly excellent. The landscape is still green from the rains, the crowds are thinner than in the peak months, and the weather is usually stable enough for trekking.

Whatever the month, mountain weather is mountain weather. Mist at dawn that burns off by mid-morning is normal year-round, and a dry-season day can still surprise you with a shower. Pack for that rather than for the forecast.

June, July, and August are the peak: the driest weather, the biggest crowds, and the earliest sell-outs. If your dates fall here, plan further ahead than feels natural.

May and September bracket the peak with nearly identical weather and noticeably more breathing room. If you can choose freely, these two months are the classic sweet spot.

April and October trade a small chance of rain for green valleys and thinner crowds. November and December stay workable, with showers building as the year ends.

January through March is the heart of the wet season: the citadel is at its greenest and quietest, and the classic Inca Trail has traditionally closed for maintenance each February, with the exact arrangements set by the authorities each year. Treks that do not use the Inca Trail route continue to operate. Rain here means mud and mist, not a washout: mornings are often clear.

Entry to Machu Picchu is rationed by the Peruvian authorities as timed, circuit-specific tickets, so "how crowded is it" matters less than "is my date still available". The scarce things sell out in a consistent order: Inca Trail permits first, then the mountain add-on climbs, then the most popular entry slots on peak dates.

How the tickets, circuits, and add-ons fit together is covered in our access overview, and the current verified rules always live in the Rules Center. If your dates are tight or already look sold out, set an alert and we will tell you the moment access for your window opens.

For peak-season dates, the safe order is: commit to your travel window first, secure the trip and its entries early, and leave the fine-tuning of hotels and day trips for later. Permits and entries are the only pieces of a Peru trip that cannot be solved with money later, so they set the schedule.

For wet-season and shoulder dates, you have far more slack, and late planning is realistic. A complete trip can often come together inside a few weeks.

If you would rather have one clear answer for your specific month and party, the trip planner gives you a feasibility read with no email required, and our packages are built around whichever entry your dates allow.
