The city of Bengaluru is located in southern India, on the Deccan Plateau at an elevation of over 900 m (3,000 ft) above sea level. The topology of Bengaluru is generally flat, though the western parts of the city are hilly.
The month of April is turning out to be good in terms of rainfall for Bengaluru. Until now the city has received 86 mm of rain against the normal of 41.5 mm.
Heavy rains occurred over many parts of the city on April 7, 10, and 24. For the last few days, a North-South trough is persisting from Madhya Pradesh to south Tamil Nadu across South interior Karnataka. The moisture feed is available from the Bay of Bengal as well as from the Arabian Sea.
The trough will get strengthen and rain activities will increase over the South Peninsula including South interior Karnataka. Bengaluru may receive on and off rains and thundershower activities until the end of the month. One or two intense spells of rain cannot be ruled out.
During the month of April, the day temperatures of Bengaluru remained above normal. But now as the pre-monsoon activities are expected to increase over the city and adjacent areas, we expect day temperatures to remain marginally below normal during the next week. By the end of the month, there are bright chances that the city will end with a large rain surplus.
