Rainfall forecasting has been one of the most scientifically and technologically challenging problems around the world in the last century. Statistical analysis of rainfall records for long periods is essential to provide information about rainfall variability and to better manage the rainfed agricultural activities such that the impact of climate change as well as changes in land use can be realistically assessed. This paper analyse the northeast monsoon rainfall of Tamil Nadu from 1902 -2009 using linear regression technique. The chi-square test was performed to test the hypothesis. This analysis revealed that the trend of northeast monsoon rainfall of Tamil Nadu is decreasing and they are not statistically significant.
