Rainfall, its pattern and its analysis is of interest to many researchers. To study the rainfall pattern and its various parameters data of daily rainfall of last 30 years is collected. An hence the appropriate distribution is fitted for the total rainfall in a season (June to September), in weeks and in months; goodness of fit test is used to verify whether the fitted distribution probabilities of receiving different rainfall for different periods are computed. To know whether there is significant difference in actual rainfall and normal rainfall in the months of June, July, Aug to September) statistical tests are applied. Graphical representation of the rainfall in the month of September shows change in pattern after 1989; the significance of rainfall before and after 1989 is tested using of weekly total rainfall with probability of dry spell and probabilities of weekly rainfall exceeding specific rainfall are computed.
