Mango Showers

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.

LOOThe Loo is a strong, hot and dry

summer wind from the west which blows over the western Indo-Gangetic Plain region of North India and Pakistan.

 It is especially strong in the months of May and June.

Due to its very high temperatures (45 °C–50 °C or 115°F–120°F), exposure to it often leads to fatal.

Since it causes extremely low humidity and high temperatures, the Loo also has a severe drying effect on vegetation leading to widespread browning in the areas affected by it during the months of May and June.
