Averages of daily values from the ERA5 reanalysis for 2023–2025 at Kathmandu's coordinates (model elevation 1301 m), via Open-Meteo (CC BY 4.0). Three recent years are not a 30-year climate normal; reanalysis smooths local extremes and tends to count more light-rain days than a rain gauge would. Daylight is sunrise to sunset on the 15th of each month.
