Indian Monsoon: very dark clouds cover the sky

Indian Monsoon – early Indian environment

The monsoon was the big weather event

In much of India, there was only one big weather event every year, and that was the monsoon. Most of the year, it was very dry and sunny in India. Everything got hot and dusty and brown.

But around May, clouds would start to gather, and it would get very muggy and heavy-feeling, and everybody would feel like they were waiting for something to happen. And then one day finally it would start raining, all at once. Buckets and buckets of water! That was the monsoon.

It would keep raining for about a month, every day, all day long. Flowers bloomed and trees put out leaves and everything started to grow, all at once. Farmers hurried to catch the water in their irrigation canals and lead the precious water to their fields. And then it would stop. The rest of the year would be dry again.

Why was the monsoon so important?

So you can see that if the monsoon didn’t come, one year, it would be very bad for the people and animals in India. There were some years when the monsoon didn’t come, and then the plants didn’t grow and people went hungry.

The monsoon and trade

India’s monsoon was also very important for trading. The monsoon winds made the ocean currents change direction. In the winter, the currents flowed north up India’s west coast, and then over to the Arabian Peninsula, Egypt, and East Africa. Most ships left about November.

In the spring, the currents flowed the other way: from Africa to India, and further east to Indonesia. Sailing ships could ride these currents and get where they were going fast, without rowing. Even more important, they could go out across the open ocean, out of sight of land, and not worry that they were going to get lost. The ocean current would automagically take them where they were going.

What’s the Retreating Monsoon?

In eastern India, there was also a second, smaller monsoon that came in September, called the Retreating Monsoon because it came at the end of the summer. The Retreating Monsoon brought less rain, but along the east coast of India, the Retreating Monsoon brought most of the rain they got.

But where there are rivers or mountains, people don’t have to depend so much on the monsoon. In northern India there are the Himalaya mountains, where there is snow all year round.

The big rivers of India

In western India (modern Pakistan), there’s the Indus River, and in eastern India, there’s the Ganges River. These two rivers account for most of the early Indian cities and farming. The rivers brought water for the fields. They also carried a lot of trade on boats. People didn’t have trucks or trains back then, and the fastest, easiest way to travel was on the rivers.
