April to October
Drier season
Better odds of clearer skies and firmer trail conditions. Expect stronger sun exposure during the day and colder nights, especially at altitude.
Seasons, rain and mountain microclimates
Inca Trail weather guide.
Understand what changes between the valleys, high passes and cloud forest—and prepare for four seasons in a single trekking day.
The essential distinction
Drier does not mean rain-free.
The trail crosses exposed Andean terrain and humid cloud forest. Seasonal patterns help you plan, but they cannot predict the exact conditions at every pass and campsite.
November to March
Rainy season
Greener slopes, more cloud and a higher chance of sustained rain. Stone steps can become slick and views may open and disappear quickly.
February note: the regulated Inca Trail normally closes for annual conservation and maintenance—not simply because it is rainy.
Weather changes with the trail
One route. Four different feelings.
SERNANP reports broad temperatures around 18°C to 5°C on the Inca Trail, with colder readings in the highest sectors. Wind, moisture and shade can make the perceived temperature feel very different.

Weather FAQs
Prepare for change, not perfection.
Check SENAMHI near departure, then follow your guide’s local assessment throughout the trek.
What is the weather like on the Inca Trail?
Conditions change quickly with elevation and terrain. One day may include strong sun, wind, cloud, rain and cold at a high pass before entering warmer, humid cloud forest.
When is the rainy season on the Inca Trail?
SERNANP identifies November through March as the rainy season. Rain remains possible at any time, particularly in the cloud forest.
How cold does the Inca Trail get?
SERNANP describes a broad trail range around 18°C to 5°C, with colder conditions in very high sectors. Exposed high camps can feel near freezing, especially on clear, dry-season nights.
Can I trust the forecast before the trek?
Use the official SENAMHI forecast as a short-term guide, not a guarantee for every campsite and pass. Mountain microclimates change quickly, so carry rain and warm layers in every season.
