Sweet spot: April, September, October. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know
- The first reviewed road product runs April–November. RN9, weather, local access and Pucará’s actual weekday calendar still require a current check.
- This four-day road version is not advertised in the summer-rain period. Choose April–November rather than assuming a clear forecast or open road.
