TEVY index has been proposed and used to evaluate the temperature variability in 4 stations in Greece. In order to establish the index, more study is necessary; so, this work is aimed to apply TEVY index across 9 stations in Nepal. Daily mean temperature is calculated for each station from the historical data of up to 44 years. Fourier Harmonic analysis is carried out to estimate the daily temperature. Then TEVY index is calculated as the squared of the difference between observed temperature and Fourier series estimated temperature. Correlation analysis carried out to check the level of fit between observed and estimated temperature values. The TEVY index shows the higher variability of temperature in hot climatic zone followed by mild climatic zone and cool climatic zone. Monthly TEVY value shows the higher variation in temperature, that coincides with the precipitation cycle of Nepal, but this statement requires more study to check its validity.
