Karnataka is one of the wettest regions of
India. Its climate is dominated by the seasonal monsoon, which sweeps in
from the southwest in June, dumping an average of 4 m of rain on the coast
before it peters out in late September.
Running in an unbroken line along the state's palm fringed coast, the
Western Ghats draped in dense deciduous forests, impede the path of rain
clouds on the east.
As a result, the landscape of the interior comprising the southern apex
of the triangular Deccan trap, known here as the Mysore Plateau is
considerably drier, with dark volcanic soils in the north and poor
quartzite-granite country to the south.
Two of India's most sacred rivers, the Tungabhadra and Krishna flow
across this sun-baked terrain, draining east to the Bay of Bengal.
