Monsoon brings welcome rains & relief from the summer heat. The term ‘Monsoon’ has been originated from the Arabic word ‘ Mawsumm’ which means season or ‘wind shift’.

South-west monsoon season starts from June 15 and lasts until September 30. In this time when the total amount of rainfall in the country is within 10 percent of the average rain over a long period. The south-west monsoon which arises in Arabian Sea Branch first hits the Western Ghats of the coastal state of Kerala, India. During the monsoon, the wind direction reverses. Moisture-laden winds from the Indian Ocean come to fill up the void, but because they can’t pass through the Himalayas region, they’re forced to rise. The gain in altitude of the clouds results in a drop in temperature, bringing about rain.
