South India has a tropical climate and depends on monsoons for rainfall. consistent with the okayöppen weather classification, it has a non-arid weather with minimum imply temperatures of 18 °C (sixty-four °F). The maximum humid is the tropical monsoon weather characterised by using mild to excessive year-spherical temperatures and seasonal heavy rainfall above 2,000 mm (79 in) according to yr. The tropical climate is experienced in a strip of south-western lowlands abutting the Malabar Coast, the Western Ghats and the islands of Lakshadweep and Andaman and Nicobar are also subject to this climate.
The tropical moist and dry weather, drier than regions with a tropical monsoon weather, prevails over the maximum of the inland peninsular vicinity except for a semi-arid rain shadow east of the Western Ghats. iciness and early summer time are long and dry intervals with temperatures averaging above 18 °C (sixty-four °F), summertime is fairly warm with temperatures in low-mendacity areas exceeding 50 °C (122 °F), and the rainy season lasts from June to September with annual rainfall averaging between 750 and 1,500 mm (30 and fifty-nine in) across the place. once the dry northeast monsoon begins in September, most precipitation in India falls in Tamil Nadu, leaving different states relatively dry. the recent semi-arid climate predominates the land east of the Western Ghats and the Cardamom Hills. The place, which includes Karnataka, inland Tamil Nadu and western Andhra Pradesh, gets between four hundred and 750 millimetres (15.7 and 29.five in) of rainfall annually with hot summers and dry winters with temperatures around 20–24 °C (68–75 °F). The months between March and might are hot and dry with mean monthly temperatures hover around 32 °C (90 °F), with 320 millimetres (thirteen in) precipitation, and without artificial irrigation, this location isn’t always appropriate for agriculture.
The southwest monsoon from June to September accounts for most of the rainfall within the place. The Arabian Sea branch of the southwest monsoon hits the Western Ghats alongside the coastal nation of Kerala and moves northwards along the Konkan coast with precipitation on coastal areas, west of the Western Ghats. The lofty Western Ghats prevent the winds from accomplishing the Deccan Plateau; therefore, the leeward place (the region deprived of winds) receives very little rainfall. The Bay of Bengal department of the southwest monsoon heads closer to northeast India, choosing up moisture from the Bay of Bengal. The Coramandel coast does no longer receive a good deal rainfall from the southwest monsoon due to the form of the land. Tamil Nadu and southeast Andhra Pradesh receive rains from the northeast monsoon. The northeast monsoon takes place from November to early March while the floor high-stress gadget is strongest. The North Indian Ocean tropical cyclones arise in the course of the yr inside the Bay of Bengal and the Arabian Sea, bringing devastating winds and heavy rainfall.
