Weather, Climate and the Factors Determining the Climate of India (Class 11 Geography, India: Physical Environment, Chapter 4)

Updated 17 October 2026 · Fact-checked

Weather is the momentary state of the atmosphere; climate is its long-period average. India has a monsoon climate, with a seasonal reversal of wind, that unites the country with South-east Asia while showing large regional contrasts. The climate is controlled by latitude, the Himalayas, distribution of land and water, distance from the sea, altitude and relief.

Notice that six separate controls all feed into India's one monsoon climate; for any 'why' question, name the factor and its effect.

Understand Weather and Climate, Unity and Diversity and the Factors Controlling the Climate of India

Why this topic matters. Factor-wise reasoning (why Agra is warmer than Darjiling, why Mumbai has an equable climate) is a standard 3-5 mark item.

1. Weather and climate. Weather is the momentary state of the atmosphere and changes within a day or a week. Climate is the average of weather over a long period and changes imperceptibly; a change may be noticed only after 50 years or more. The elements are temperature, pressure, wind direction and velocity, humidity and precipitation.

2. Monsoon. A climate associated with a seasonal reversal in wind direction. India has a hot monsoon climate, found across South and South-east Asia.

3. Unity. The monsoon unites India with the rest of South-east Asia.

4. Diversity. Summer temperature reaches 55 degrees C in western Rajasthan while winter drops to minus 45 degrees C around Leh. The daily range is only 7-8 degrees C in Kerala and the Andamans but large in the Thar. Cherrapunji and Mawsynram receive over 1,080 cm; Jaisalmer rarely gets over 9 cm. Most of India rains in June-September but coastal Tamil Nadu gets rain at the start of winter.

5. Latitude. The Tropic of Cancer passes through central India. The area south of it is tropical, with high temperatures all year and small ranges; the area north is sub-tropical or temperate with extreme conditions and large ranges.

6. Himalayas. An effective climatic divide: they shield the subcontinent from cold northern winds and trap the monsoon winds, forcing them to shed moisture within India.

7. Land and water. The Indian Ocean lies on three sides with a mountain wall in the north. Land heats and cools faster than water, so differential heating creates seasonal pressure differences and reverses the monsoon winds.

8. Distance from the sea. Coastal areas (Mumbai, the Konkan) have an equable climate; interiors (Delhi, Kanpur, Amritsar) have strong seasonal contrasts.

9. Altitude and relief. Temperature falls with height because the air is thinner: Agra is 16 degrees C in January and Darjiling 4 degrees C. Relief shapes rainfall: windward Western Ghats and Assam are wet from June to September while the leeward southern plateau stays dry.

Weather and Climate, Unity and Diversity and the Factors Controlling the Climate of India in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Two hill stations

Suppose a traveller finds that a plains town and a hill town at the same latitude differ by 12 degrees C on a January morning.

Which factor explains this?

Try it first, then show the solutionSolution
  1. Air is thinner at height and holds less heat.
  2. Temperature falls with altitude.

Answer: Altitude, as in Agra 16 degrees C and Darjiling 4 degrees C.

Memory hook: Higher means colder.

Coast and inland city

Suppose two cities at the same latitude have a yearly temperature range of 6 degrees C and 25 degrees C respectively.

Which is coastal, and why?

Try it first, then show the solutionSolution
  1. Sea water heats and cools slowly, keeping the coast equable.
  2. Interior places have strong seasonal contrasts.

Answer: The city with the 6 degrees C range is coastal.

Memory hook: Sea moderates.

Weather and Climate, Unity and Diversity and the Factors Controlling the Climate of India: solved examples

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Climate definition · 1 mark · MCQBoard level

Climate of a place is best described as:
(A) the state of the atmosphere at a moment
(B) the average of weather over a long period
(C) the rainfall of one season
(D) the temperature of one day

Try it first, then show the solutionSolution
  1. Climate is the long-period average of weather (1 mark).

Answer: (B)

Example 2: Role of Himalayas · 2 marks · Very short answerBoard level

State two ways in which the Himalayas influence the climate of India. (2 marks)

Try it first, then show the solutionSolution
  1. Shield against cold northern winds (1 mark).
  2. Trap the monsoon winds so they shed moisture in India (1 mark).

Answer: The Himalayas shield the subcontinent from the cold northern winds of central and eastern Asia and trap the monsoon winds, forcing them to give rain within India.

Example 3: Agra and Darjiling · 3 marks · Short answerHarder board level

Agra records 16 degrees C and Darjiling 4 degrees C in January although they lie at similar latitudes. Explain. (3 marks)

Try it first, then show the solutionSolution
  1. Latitude is similar so it cannot explain the 12 degrees C difference (1 mark).
  2. Darjiling is much higher; air is thinner at height (1 mark).
  3. Temperature falls with altitude, so Darjiling is colder (1 mark).

Answer: Latitude cannot account for the difference. Altitude does: Darjiling lies high in the hills where the air is thin, and temperature falls with height, so it is about 12 degrees C colder than Agra.

Example 4: Assertion and reason: coast · 1 mark · Assertion-reasonHarder board level

Assertion (A): Mumbai has a more equable climate than Delhi.
Reason (R): Water heats and cools more slowly than land.
(A) Both true, R explains A
(B) Both true, R does not explain A
(C) A true, R false
(D) A false, R true

Try it first, then show the solutionSolution
  1. Coastal Mumbai is moderated by the sea; the reason is the correct explanation (1 mark).

Answer: (A)

Example 5: HOTS: unity yet diversity · 5 marks · Long answerHOTS / competency

A student writes that India cannot have a single "monsoon climate" because Churu records 50 degrees C while Tawang is only 19 degrees C on the same June day. Evaluate this view with reference to unity and diversity, naming two factors that explain the difference. (5 marks)

Try it first, then show the solutionSolution
  1. Monsoon type is identified by seasonal reversal of winds, which unites the country (1 mark).
  2. Large regional differences are sub-types within it (1 mark).
  3. Churu is a low, interior, dry location far from the sea (1 mark).
  4. Tawang is a high-altitude Himalayan site and altitude lowers temperature (1 mark).
  5. So the claim confuses sub-types with the overall climate; India is monsoonal in rhythm with regional variation (1 mark).

Answer: The student is only partly right. The monsoon climate is defined by the seasonal reversal of winds and shared rhythm of seasons, which unites India. Within it, regional variations arise from factors such as altitude and distance from the sea: Churu is an interior lowland location with intense heating, while Tawang is high in the Himalayas where temperature falls with height. These are sub-types of a monsoon climate, not evidence against it.

Where students lose marks in Weather and Climate, Unity and Diversity and the Factors Controlling the Climate of India

The slips examiners see most often, and what to write instead.

  • Mistake: Treating weather and climate as the same

    The words are used loosely.

    Wrong working

    Climate is today's rain or heat.

    Right working

    Climate is the long-period average, not a single day.

    Do this: Use "average over a long period".

    Usually costs: 1 mark.

  • Mistake: Naming the Himalayas only as a barrier to cold winds

    Only one role remembered.

    Wrong working

    Himalayas only stop the cold winds.

    Right working

    They also trap the monsoon winds so moisture is shed in India.

    Do this: Give both roles.

    Usually costs: 1 mark.

  • Mistake: Using latitude for Agra versus Darjiling

    Both are in the north.

    Wrong working

    Darjiling is colder because it is further north.

    Right working

    Altitude: the air is thinner at height.

    Do this: Compare latitudes first, then altitude.

    Usually costs: 1 mark.

Exam tips

  • Write all six factors in a list with one example each.
  • Quote numbers exactly: 55 degrees C, minus 45 degrees C, 1,080 cm, 9 cm.
  • Define climate with the 50 years or more idea.

Practice questions on Weather and Climate, Unity and Diversity and the Factors Controlling the Climate of India

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

  1. Q1 · 1 mark · MCQBoard level

    Which factor makes coastal places like Mumbai have little variation in temperature?
    (A) latitude
    (B) distance from the sea
    (C) relief
    (D) the Himalayas

    Hint

    Sea moderates.

    Answer

    (B)

  2. Q2 · 2 marks · Very short answerBoard level

    Differentiate weather from climate. (2 marks)

    Hint

    Duration.

    Answer

    Weather is the momentary state of the atmosphere and changes quickly, within a day or week. Climate is the average of weather over a long period and changes only imperceptibly, over 50 years or more.

  3. Q3 · 3 marks · Short answerHarder board level

    How does the Tropic of Cancer divide India into two climatic zones? (3 marks)

    Hint

    South and north.

    Answer

    The Tropic of Cancer passes through central India. The region south of it is tropical, with high temperatures throughout the year and small daily and annual ranges. The region north of it is sub-tropical and temperate, with extreme climates and large daily and annual ranges.

  4. Q4 · 3 marks · Short answerHarder board level

    Explain how differential heating of land and water produces the reversal of monsoon winds. (3 marks)

    Hint

    Pressure.

    Answer

    Water heats and cools slowly while land heats and cools quickly. This creates different pressure zones over land and sea in different seasons. Winds blow from high to low pressure, so their direction reverses with the seasons, which is the monsoon.

  5. Q5 · 4 marks · Short answerHOTS / competency

    Use two examples from the chapter to show that relief controls rainfall in India. (4 marks)

    Hint

    Windward and leeward.

    Answer

    The Western Ghats and Assam are on the windward side of the monsoon winds, so they get heavy rain from June to September. The southern plateau lies on the leeward side of the Western Ghats and stays dry. Relief therefore forces moist air up on one side and leaves the other side in a rain-shadow.
