Meghalaya, one of the Seven Sisters States located in the North Eastern Himalayan region of India, is known for two high-rainfall places, i.e. Sohra and Mawsynram, but the state often faces water crisis during the post-monsoon season. Weekly, monthly and seasonal rainfalls were analysed for the state by calculating mean, coefficient of variance, extreme value, etc. To estimate the effect of rainfall on rice yield regression model was applied. The month of August receives highest average rainfall of 1108.30 mm, but the inter year variation is very high (CV = 49.69%). Increasing linear trends were observed for pre-monsoon, monsoon and post-monsoon over the study period. The quantum of June rainfall (0.75%) and monsoon maximum temperature (13.35%) has a positive and significant impact on yield of kharif rice, whereas the quantum of August rainfall (−0.46%) has a negative and significant impact on the yield of rice.
