In the month of June it has had 477 mm of rain as opposed to the normal average rainfall figure of 457 mm. In the last 24 hours, Port Blair received only 7 mm of rain. The heaviest rain so far has been 144 mm on 6th June.
Till few days back Andaman had consistently been getting over 100 mm of rain due to multiple cyclonic circulations in the Bay of Bengal, which were not affecting Monsoon rains over Northeast India. Though now, rain figures may not pick up much as the Monsoon surge in the Bay of Bengal is likely to shift towards East and Northeast India, sharply reducing surplus rainfall figure in Andaman as well as in other regions.
