How Do the Summer and Winter Monsoons Differ?

The summer monsoon brings heavy rains and creates a moisture-rich atmosphere, while the winter monsoon generates long periods of dry and arid conditions. The summer monsoon generally begins in April and lasts through late September, while the winter monsoon arrives in October and ends in March. Rainfall produced during the summer monsoon can be very intense; flash floods and even crop damage are not uncommon in regions subject to the monsoon's effects.
