Peru Cusco Weather in October — Climate Guide

October is high for Cusco.
October is the wet-season-returning shoulder — first half (October 1-15) still dry-season conditions, second half (October 16-31) sees afternoon showers building, rainfall climbs to 50mm, rain days to 8. Hotel rates 30-40% below July-August peak. Excellent value-for-conditions if you target October 1-15 specifically and accept some shower risk. Inca Trail still operating + permits easier than September. Machu Picchu sunrise reveals at 80% reliability first half, dropping to 60% second half. Sacred Valley ruins still mostly dry + photogenic with green-returning landscapes from early rains. Cusco nights warming to 5°C average — fleece + down jacket still wise for sunrise.
