About Northeast Monsoon
The period between October to December in peninsular India is referred to as the northeast monsoon season. The northeast monsoon used to be called ‘post-monsoon season’ or ‘retreating southwest monsoon season’.
The northeast monsoon is a major period of rainfall activity over the southern peninsula, especially coastal Andhra Pradesh, Rayalaseema and the Tamilnadu-Pondicherry region. For Tamilnadu, this is the main rainy season accounting for about 48% of the annual rainfall.
Generally, northeast monsoon rains occur in spells of about 3 to 4 days duration. Spells exceeding 4 days occur less often and there are long spells of dry weather with little or no rain. Rainfall is concentrated in the afternoon, evening or early part of the night, except when a depression is formed nearby.
