50 free Monsoons trivia questions with answers — nature quiz, new questions added Aug 2026.
This monsoons trivia quiz covers the science and the geography of the world's great seasonal wind reversals. It starts with the basics: where the word comes from, why land heats faster than sea, what the Intertropical Convergence Zone does and why the Tibetan Plateau matters. Then it follows the South Asian monsoon from its June 1 arrival in Kerala up the Western Ghats and around the Bay of Bengal to the wettest places on Earth in the Khasi Hills, and back out again as the northeast monsoon that waters Tamil Nadu. Other questions cover the East Asian plum rains, the West African monsoon and the harmattan, Australia's Wet, the North American monsoon that turns Arizona skies black each July, and the ENSO and Indian Ocean Dipole patterns that decide whether India gets drought or flood. Numbers questions test rainfall records, the monsoon's share of India's rain and its grip on the economy. Difficulty runs from easy to expert and is shown on every question. Every answer was checked against a reference page and each question carries its citation. Try our weather and India quizzes next.

Q 01Traditionally, how is a monsoon defined?
A seasonal reversing wind
The word is now also used for the seasonal swing in rainfall tied to the migration of the Intertropical Convergence Zone.
Q 02The English word "monsoon" ultimately derives from an Arabic word meaning what?
Season
It reached English through Portuguese monção, and partly through early modern Dutch.
Q 03Which language did "monsoon" pass through on its way from Arabic into English?
Portuguese
Portuguese sailors were the first Europeans to work the Indian Ocean trade winds regularly.
Q 04The migration of which atmospheric feature is now considered the driver of monsoons?
The Intertropical Convergence Zone
Its northern and southern limits shift with the land–sea heating contrast each year.
Q 05Why do continents warm up more quickly than the sea in summer, setting up monsoon winds?
Land has a lower heat capacity
Water also mixes heat down to about 50 metres by convection, while rock and sand can only conduct it.
Q 06In summer, why does the air over heated land develop low pressure?
Warm air expands and rises
Cooler, higher-pressure air over the ocean then flows inland as a moist sea breeze on a continental scale.
Q 07Which direction do most summer monsoon winds have as their dominant component?
Westerly
Winter monsoons are mostly easterly and tend to subside, bringing drought rather than rain.
Q 08The strengthening of the Asian monsoon has been linked to the uplift of which highland region?
The Tibetan Plateau
It followed the collision of India with Asia about 50 million years ago.
Q 09How many major monsoon systems does the world have, according to the standard classification?
Four
They are the West African, South Asian–Australian, North American and South American monsoons.
Q 10During which months does India's southwest monsoon occur?
June to September
It normally arrives at the end of May or start of June and fades in late September or early October.
Q 11Which arid region's summer heating creates the low pressure that draws the monsoon into India?
The Thar Desert
Moisture-laden winds from the Indian Ocean rush in to fill the void.
Q 12Which mountain range forces the monsoon winds to rise and drop their rain rather than pass into Central Asia?
The Himalayas
Some parts of the subcontinent receive up to 10,000 mm of rain a year as a result.
Q 13Which Indian state is the first to receive rain from the southwest monsoon?
Kerala
The Arabian Sea branch hits the Western Ghats there first.
Q 21What term describes the sudden switch to wet, humid weather when the monsoon arrives in India?
Bursting
The jet stream theory says the shift happens abruptly once the Tibetan Plateau heats up more than the Himalayas.
Q 22By what other name is the northeast phase, when cold air sweeps towards the sea, known?
The retreating monsoon
Cold, dry air sweeps down from the Himalayas and picks up moisture over the Bay of Bengal.
Q 23Which Indian city is watered mainly by the northeast monsoon rather than the southwest one?
Chennai
Tamil Nadu gets 50% to 60% of its rain from the northeast monsoon between October and December.
Q 14What date is regarded as the official onset of the monsoon in India?
June 1
That is when the rains are expected to arrive in the southernmost state.
Q 15Into which two arms does the southwest monsoon split at the southern tip of India?
Arabian Sea and Bay of Bengal
One runs up the Western Ghats, the other swings around the Bay of Bengal towards the eastern Himalayas.
Q 16Which town on the southern slopes of the Khasi Hills in Meghalaya is one of the wettest places on Earth?
Mawsynram
Its average annual rainfall is 11,872 mm, and it recorded 1,003.2 mm in a single day in June 2022.
Q 17What is the average annual rainfall of the Khasi Hills town reputed to be the wettest place on Earth?
11,872 mm
Two Colombian towns, Lloró and López de Micay, dispute its claim to be the wettest place on Earth.
Q 18Which town, also called Sohra, holds the records for rain in a single month and year?
Cherrapunji
It got 9,300 mm in July 1861 and 26,461 mm in the twelve months from August 1860.
Q 19How much rain fell in the Khasi Hills in July 1861, the record for a calendar month?
9,300 mm
That is more than 30 feet of water in 31 days.
Q 20Roughly what share of India's annual rainfall comes from the monsoon?
Nearly 80%
A delay of a few days can hurt an economy in which agriculture employs about 70% of the population.
Q 24In which months does the northeast monsoon bring rain to southern Asia?
October to December
That is when the surface high-pressure system over the cooling northern landmass is strongest.
Q 25What is the northeast monsoon called in the Philippines?
Amihan
It brings cool, dry air across the islands during the northern winter.
Q 26What is the East Asian summer rain belt called in China?
Meiyu
The name means plum rain; the same belt is called Jangma in Korea and Bai-u in Japan.

Plum
The belt moves north from Indochina in May to northern China and Korea by July.

The harmattan
The ITCZ reaches West Africa around June 22 and retreats south by October.
Q 29Which semi-arid African belt depends on the West African monsoon for most of its precipitation?
The Sahel
The monsoon comes from the temperature and humidity contrast between the Sahara and the equatorial Atlantic.
Q 30During which months does the North American monsoon occur?
Late June to September
It starts over Mexico and reaches the southwestern United States by mid-July.
