The Big Questions
- What makes India’s climate so diverse?
- What are the monsoons? How are they formed?
- What is the effect of climate on economy, culture and society?
- How can understanding the climate help us to prepare for natural disasters?
- What is climate change? What are its consequences?
Weather
Weather is what we experience from hour to hour or day to day. It may be rainy, sunny, windy, hot or cold.
Climate
Climate is the long-term pattern of weather experienced by a region. It is studied over several decades.
Easy difference:
| Weather | Climate |
|---|---|
| Short-term condition of the atmosphere. | Long-term pattern of weather. |
| May change every day. | Changes slowly over many years. |
Seasons
Seasons occur as the Earth revolves around the Sun. Different seasons bring changes in weather and human activities.
In many parts of India, the traditional year is divided into six ritus:
- Vasanta – Spring
- Grishma – Summer
- Varsha – Rainy season
- Sharad – Autumn
- Hemanta – Pre-winter
- Shishir – Winter
Festivals, food, clothes, crops and many traditions are connected with seasons.
India has diverse climates
- Himalayas: Alpine climate with cold, snowy winters.
- Hilly areas: Temperate climate with moderately cold winters and pleasant summers.
- Northern Plains: Subtropical climate with hot summers and cold winters.
- Thar Desert: Arid climate with very hot days, cool nights and little rainfall.
- Western Coast: Tropical wet climate with heavy monsoon rainfall.
- Deccan Plateau: Semi-arid climate with hot summers and moderate rainfall.
- Eastern India and Southern Peninsula: Tropical climate with wet and dry periods.
a) Latitude
Page 49Places near the Equator are warmer because the Sun’s rays fall more directly on them. Places at higher latitudes receive less heat and are colder.
Example: Kanniyakumari and the Nicobar Islands are warm, while Srinagar is much cooler.
b) Altitude
Page 50Temperature decreases as altitude increases. Higher places are therefore generally cooler than the plains.
Examples: Shimla, Darjeeling, Ooty and Munnar are cooler because they are at higher altitudes.
c) Proximity to the Sea
Page 51The sea moderates temperature. Coastal places usually have cooler summers and milder winters.
Example: Mumbai has a smaller temperature range than Nagpur.
d) Winds
Page 52Winds can carry warm, cold, dry or moist air from one region to another. Sea winds may bring moisture and rainfall.
e) Topography
Page 52–53Topography means the physical features of an area, such as mountains, hills, valleys, slopes and coasts.
The Himalayas and Karakoram help protect the Indian subcontinent from very cold winds from Central Asia.
Microclimate
A microclimate is the climate of a small area that is different from the climate of the surrounding region.
Examples include enclosed valleys, forests and urban heat islands.
What is a Monsoon?
The word monsoon comes from the Arabic word mausim, meaning season.
Monsoons are seasonal winds that change direction during different times of the year.
Summer Monsoon
During summer, land heats faster than the ocean. This creates low pressure over the land. Moist winds blow from the cooler ocean towards the land and bring rainfall.
Winter Monsoon
During winter, land cools faster than the ocean. The land develops higher pressure and winds blow towards the ocean. These winds are mostly dry.
Southwest Monsoon
The southwest monsoon usually reaches the southern tip of India in early June and gradually covers the country by mid-July.
The Western Ghats act as a barrier. Their western slopes receive heavy rainfall, while the Deccan Plateau receives less rainfall.
Northeast Monsoon
In winter, winds reverse direction. Some winds pass over the Bay of Bengal, collect moisture and bring rainfall to parts of eastern and southern India.
Important Monsoon Facts
- Mawsynram in Meghalaya receives extremely high average annual rainfall.
- Monsoon rainfall is very important for agriculture.
- Rivers, soil, crops and many livelihoods depend on monsoon rainfall.
- Traditional knowledge has helped people predict the arrival of monsoon rains.
Climate affects our daily life, culture, festivals, agriculture and economy.
Climate and Culture
Many Indian festivals are connected with seasons and agriculture. Examples include Baisakhi, Onam, Pongal, Lohri and Makar Sankranti.
Climate and Agriculture
Farmers depend on suitable temperature and rainfall for growing crops. A weak monsoon can reduce agricultural production.
Climate and Economy
Climate affects farming, industries, water availability, food prices and employment.
Cyclones
A cyclone can form when a strong low-pressure system develops over the sea. Moist air moves towards the low-pressure centre and strong winds rotate around it.
The calm, cloudless centre of a cyclone is called the eye of the cyclone.
Floods
A flood occurs when water overflows into normally dry land. Heavy rainfall, overflowing rivers and excessive water can cause floods.
Floods are common during the monsoon in many parts of India.
Landslides
A landslide is the sudden collapse or movement of rock, soil or debris down a slope.
Heavy rain, earthquakes and volcanic activity can trigger landslides. Human activities such as cutting forests and unsafe construction can increase the risk.
Forest Fires
Forest fires are uncontrolled fires that spread through vegetation. Dry conditions, drought, strong winds and human carelessness can cause them.
They damage forests, wildlife, air quality and local communities.
What is Climate Change?
Climate change means significant and long-term changes in climate. These changes can affect temperature, rainfall and weather events.
Main Human Causes
- Burning fossil fuels
- Deforestation
- Harmful industrial activities
- Excessive and wasteful consumption
Global Warming
Greenhouse gases trap heat in the atmosphere. Human activities have increased these gases, causing extra warming and changes in climate patterns.
How can we reduce climate change?
- Reduce greenhouse gas emissions.
- Plant and protect trees.
- Use renewable energy.
- Save energy.
- Follow sustainable lifestyles.
- Prepare communities to adapt to climate changes.

Is the place near the sea, in the mountains, or in the desert?
How do these factors affect the climate there?
| City | Location | Climate | Reason |
|---|---|---|---|
| Leh | Mountains | Alpine and cold | High altitude makes it cold. |
| Chennai | Near the sea | Tropical | The sea keeps temperatures from becoming very extreme. |
| Delhi | Northern plains, inland | Subtropical | It has hot summers and cold winters. |
| Panaji | Near the sea | Tropical wet | It receives heavy monsoon rainfall. |
| Jaipur | Near the Thar Desert | Arid | It receives little rainfall and has very hot summers. |
Label where the winds blow in summer and winter
Show the direction of winds during the monsoon
In summer, draw arrows from the Indian Ocean towards India. These are the southwest monsoon winds. They bring moisture and rainfall.
In winter, draw arrows from the land towards the ocean. These are the northeast monsoon winds.
The student should clearly mark the Arabian Sea, Bay of Bengal, India and the direction of the arrows on the map.
A student can make a colourful poster with the heading “Festivals, Farming and Weather in India”.
| Festival | Connection |
|---|---|
| Baisakhi | Harvest festival associated with farming in North India. |
| Onam | Harvest festival celebrated in Kerala. |
| Pongal | Harvest festival celebrated in Tamil Nadu. |
| Lohri | Seasonal and harvest-related festival celebrated in North India. |
| Makar Sankranti | Festival connected with the seasonal change and harvest in many parts of India. |
Add drawings or pictures of crops, farmers, rain, the Sun and the festivals.
Dear Diary,
Today I prepared my field for the rainy season. I cleaned the water channels and checked my seeds and farming tools. I also made sure that the stored grains would remain dry. I am hoping for good rainfall and a healthy crop this year.
Flood
A flood occurs when water covers land that is normally dry. Heavy rainfall, overflowing rivers and poor drainage can cause floods.
Impacts: Floods can damage homes, roads, crops and bridges. They can also affect people, animals and local businesses.
What individuals can do: Keep emergency supplies ready, avoid unsafe flooded areas and follow official warnings.
What communities can do: Keep drains and waterways clear, plant trees and help people during emergencies.
What the government can do: Improve drainage, provide early warnings, strengthen disaster-response systems and quickly provide rescue and relief.
