The climate data (maximum temperature, minimum temperature and rainfall) of forty year (1974- 2013) was analysed for kharif (May to October) and rabi (November to April) seasons in Punjab, India. The non-parametric Mann-Kendall and Sen’s methods were used to determine trend (positive or negative) in climate data over a period of 40 years. A decrease in rainfall and increase in temperature from northeast to south-west Punjab during both the kharif and rabi seasons was observed. No significant temporal variation was observed in maximum temperature and rainfall during both the seasons, but a significant increase in minimum temperature over the years was observed in different zones of Punjab. On an average, minimum temperature is increasing at 0.05oC per year during both the seasons.
