April 2016 has turned out to be the driest one in the last many years. Accordingly, it was also one of the hottest on record with temperatures continuously settling above 40 degree Celsius at several places. Heatwave like conditions did not even spare the hills of North India. On the other hand, Northeast India remained cool with rains lashing the region throughout the month of April.
Record-breaking temperatures were witnessed in several areas in the country with Bangalore losing its pleasant weather crown. Heatwave in Telangana andOdisha claimed hundreds of lives as well.
Pre-Monsoon showers were almost absent from the country. Cumulatively, India received 30.8 mm of rainfall against the normal of 38.9 mm. This amounted to 19% of rainfall deficiency, which actually falls in the ambit of normal rains. However, the situation was grim as most of the contribution came from Northeast India. North, Central and West India performed extremely poorly in terms of pre-Monsoon showers.
