Mango showers, or ‘mango rains’, is a colloquial term to describe the occurrence of pre-monsoon rainfall. Sometimes these rains are referred to generically as ‘April rains’ or ‘Summer showers’. They are notable across much of South and Southeast Asia, including India, and Cambodia. These rains normally occur from March, although their arrival is often difficult to predict. Their intensity can range from light showers to heavy and persistent thunderstorms. In India, the mango showers occurs as the result of thunderstorm development over the Bay of Bengal.
