This study is based on secondary data of weather parameters such as rainfall, relative humidity, maximum temperature and minimum temperature and their effect on rice crop yield in Thrissur district of Kerala by using the data from 2004-2005 to 2018-2019. The main aim of this study is to analyze the climatic variability and its effect of rice productivity in different weather seasons. The result obtained from analysis of relationship of rice production with weather parameters shows non-significant and negatively correlated for rainfall. The rice production was positively correlated and non-significant with maximum and minimum temperature, Relative humidity was highly significant and negatively correlated with rice production. In case of multiple regression analysis, relative humidity shows significant and negatively influence on rice production. In prediction of rice production, among different linear and non-linear models, cubic model was found to be the best for Thrissur district rice production (highest R2 value)with respect to all weather parameters (viz, rainfall, relative humidity, maximum temperature and minimum temperature).
