What you gain in September
- ↑September retains essentially the same excellent dry-season weather as July–August (only 40mm rain, 7.5 sunshine hours) but the school holiday crowds have returned home and prices drop significantly
- ↑Machu Picchu timed-entry slots are much more easily booked; the site is quieter than peak season and the experience is meaningfully more atmospheric
- ↑Inca Trail Classic permits are available — September is one of the best months to book and hike without the scramble of peak-season competition
What you sacrifice
- ↓The very tail of the dry season; by late September occasional afternoon clouds begin to build, hinting at the transition — weather is still excellent but July clarity is starting to wane
- ↓Hotel prices, while lower than July–August, are still notably higher than the wet-season trough; September is a sweet spot, not a bargain
- ↓Altitude acclimatisation is unavoidable at 3,400m — budget at least a full day in Cusco before any physical activity, however fit you are
