Droughts happen when there is not enough rainfall for a longer period of time. When there is so little precipitation (rainfall, snow etc.) the whole region starts to dry out. Sometimes a drought take decades to develop fully and they are very difficult to predict. Rainfall data of 15 years (2001-2015) based on standard weeks was analyzed for Etawah district of Uttar Pradesh. The monthly maximum rainfall at different probability levels was calculated using Gumbel’s Probability method. The daily rainfall data series was divided into annual, seasonal, monthly and weekly data series. A year was divided into three seasons i.e. monsoon (June to September), winter (October to January) and summer (February to May). The last day of every year (365th day) and last two days of a leap year are accounted as 52nd week. It was observed that the maximum number of drought weeks during the 15 years period was 15 times during the 19th week while, the minimum numbers of drought weeks was 6 times which were found in the 33th and 35th standard week. The maximum number of surplus weeks during the 15 years period was 4 during 27th, 32th and 34th week however, the minimum numbers of surplus weeks i.e. 0 were found in the 6th and 19th standard week of the year.
