During the months of February to May, the temperature across India soars.
As the heat builds, the hot air rises. Cooler air from over the India Ocean rushes in to replace it. This air, having been situated over the ocean for months, is full of moisture and brings torrential rain to much of the country.
Some parts of the country receive 80% of their annual rainfall in the summer monsoon, which runs from June to October.
