As expected, June has finally ended below average rainfall. As on June 29, the countrywide cumulative rainfall deficiency stands at 12%. And, with rains dipping slightly during the last 24 hours, we do not expect to this deficiency to reduce much.
June has witnessed huge variations in the daily rainfall recorded. This month managed to see only 10 days of excess rainfall. The initial week was very poor wherein daily rainfall deficiency hovered around 30%. However, the weeks followed by saw some improvement.
The countrywide rainfall deficiency which once stood at 25% on June 17, started decreasing June 18 onwards by 1% every day. However, it was the last three days of the month which changed the scenario.
Country witnessed significant drop of 5% in rainfall deficiency in span of just three days, which is very rare. Peninsular India, Northwest India and Central India performed well in terms of rainfall on June 28.
This was on account of the twin Monsoon systems developing in Bay of Bengal and Arabian Sea each that kept the Monsoon surge active over entire country. Rains had also spread over the places that are yet to see the onset of Monsoon.
June 28 was the rainiest day of the month that recorded 10.8 mm of rain across the country against the normal average of 7.9 mm. This day, country rainfall was excess by 37% which is the highest so far in the season.

Factor affecting Monsoon 2016
Southwest Monsoon was under the influence of El-Nino effect during the early days of the month. Also, we had expected El-Nino to taper down after June only. Hence, remnants of the system kept affecting the Monsoon.
But the intensity of El-Nino is now decreasing and at present, the current status of Nino 3.4 that affects the Southwest Monsoon stands at -0.4°C. This is for the first time that indices have dropped this low.
Not only this, ocean conditions also respond gradually to the temperature change and it is not very rapid.
