Best Time to Visit Machu Picchu: Dry Season (May–September)

The optimal time to visit Machu Picchu is the dry season, May through September. During these months:

• Weather: Clear, sunny days (18–22°C / 64–72°F); cold nights (0–5°C / 32–41°F). Minimal rain.
• Trails: Inca Trail, Salkantay, and other treks are dry and stable.
• Views: Unobstructed panoramas of the citadel and surrounding peaks.

Peak Crowds: July–August (European/North American summer). For fewer people, aim for May, June, or September—weather remains excellent.

Wet Season (October–April): Frequent heavy rain, muddy trails, landslide risk, cloud-obscured views. Inca Trail closes February for maintenance. Not recommended.

Essential Tips:

• Book entry tickets and Inca Trail permits 6+ months ahead.
• Acclimatize in Cusco (3,400 m) 2–3 days prior.
• Pack layers, rain gear, sun protection, sturdy boots.
• Enter at 6 AM for sunrise and thinner crowds.

Dry season offers the quintessential Machu Picchu experience.
