A study of the onset of monsoon over Delhi and neighbourhood extending for a period of fifty years is attempted in this paper. Widespread rain over the districts around the station has been chosen as the criterion for fixing the date of onset of the monsoon. The rainfall data of the provincial rain gauge stations have been examined. From the examination of the data of the past 50 years, the mean date of onset of monsoon over Delhi has been found and the standard deviation worked out. The frequency diagram shows approximately normal distribution about the mean date. Synoptic situations on these dates have also been examined and the onsets are roughly classified under different synoptic situations that brought in the monsoon during the last 50 years.
