A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. These winds cause wet and dry seasons throughout much of the tropics and are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. They regularly last for two months, so smile, get out your umbrellas and your rubber flip-flops because the rainy season will be here at least until January if the nation is blessed with that much water to fill the wells and increase groundwater.
