Source: NASA POWER (public domain), 2001–2025 monthly averages on a ~50 km satellite and reanalysis grid, so coasts and valleys can differ from what's shown. Temperatures were adjusted from the grid cell's ~3,740 m (12,271 ft) to Cusco's ~3,336 m (10,945 ft) elevation using the standard lapse rate of 6.5°C per 1,000 m. Precipitation includes snow as melted water; daylight is calculated from latitude. Check a forecast before you go.
