Rainfall has enormous impact on weather and climate. An investigation on impact of rainfall on coconut productivity was taken place in Kozhikode and Malappuram districts of Kerala, to identify the variation in coconut production on an account of secondary data based on rainfall collected for a time period from 1991 to 2015 (25 years). Panel data analysis revealed that rainfall during 3rd (July-September) and 4th (October-December) quarters was found to have significant negative impact on coconut production. Amount of rainfall observed during 1st (Januvary-March) and 2nd(April-June) quarters has positive non-significant impact on coconut production. The growth trend of rainfall showed an increasing trend in Kozhikode district whereas Malappuram district had a decreasing trend over the years.
