Changes in climatic parameters like rainfall and temperature has increased in last few decades. These changes have impact on daily life. So, assessing the change in trend of climate variables will help to take measures to overcome these problems. In this paper annual and seasonal trend of climate variables like rainfall, minimum and maximum temperature of India from year 1901 to 2021 have been analyzed using non-parametric tests like Mann-Kendall, Modified Mann-Kendall and Sen’s Slope Estimator. To detect the change point Pettit homogeneity test has been used. Results revealed that there is increasing trend in both annual and seasonal temperatures. There is decreasing trend in rainfall except pre-monsoon rainfall. This indicates that there will be increase in temperature and decrease in rainfall in future days.
