QUICK ANSWER

The six seasons of Assam are Grishmo (summer), Borxa (monsoon), Xorot (early autumn), Hemonto (late autumn), Xit (winter) and Bosonto (spring). Each season, or Ritu, covers two months of the traditional Assamese calendar, which begins in mid-April with Bohag Bihu. Together, they shape the state’s farming cycle, its three Bihu festivals and the best time to travel.

Ask someone in Guwahati what season it is and you might get an answer you did not expect. Not just “summer” or “winter”, but Xorot or Hemonto. For centuries, Assamese families have read the year in six chapters instead of four, and each chapter brings its own weather, crops, flowers, food and festivals.

Understanding the six seasons of Assam is the simplest way to plan a trip that matches what you actually want to see. Want the thunder of Bihu drums? Come in mid-April. Want to spot a one-horned rhino? Pick the cool, dry months. Want to watch the Brahmaputra at its most powerful? Visit during the rains.

In this guide, you will learn what each season looks and feels like, which festivals fall in it, what to pack, and which season suits your kind of trip.

Why Does Assam Follow Six Seasons Instead of Four?

Assam’s traditional calendar, known as Bhaskarabda, has twelve solar months, running from Bohag in mid-April to Sot in the following spring. These months are grouped in pairs to form the six-season Ritu system followed across much of India, with names and timings shaped by local life.

The six-season model fits Assam remarkably well. A four-season calendar jumps straight from monsoon to winter. Yet anyone who lives along the Brahmaputra knows there is a bright, golden stretch in between, when the rains stop, the skies clear and the rice ripens. The six Ritus give a name to these in-between moments, which is why farmers, cooks and festival planners still rely on them.

A quick pronunciation tip: in Assamese, the letter “X” in words like Xorot and Xit is spoken as a soft, breathy sound close to “h” or “kh”. So Xorot sounds roughly like “Ho-rot” and Xit like “Heet”. You may also see these seasons spelled as Sharad, Sheet or Barsha in other sources.

Dates are approximate. Assamese months begin when the sun moves into a new zodiac sign, which usually happens around the middle of each Gregorian month.

Grishmo (Mid-April to Mid-June): Bihu Drums and Summer Storms

Grishmo opens the Assamese year, and it opens loudly. The first day of Bohag marks Bohag Bihu, also called Rongali Bihu, the festival of joy that welcomes the new year and the start of the farming cycle. You will hear the beat of the dhol and the pepa, a buffalo-horn pipe, and see dancers in golden muga silk with kopou phool, a delicate foxtail orchid, tucked into their hair.

Bohag Bihu is one of the three Bihu festivals that mark key moments in the farming year. Its first day, Goru Bihu, honours cattle. Over the following days, groups of singers called husori go from home to home, sharing songs and blessings.

Grishmo is also the season of Bordoisila, the sudden evening storms that sweep across the valley. In folklore, Bordoisila is a daughter who returns to her mother’s home in Bohag, arriving with wind and rain. Days turn warm and humid, but these storms often cool the evenings.

Travel tips for Grishmo

  • If Bohag Bihu is on your list, book your Guwahati stay early, as cultural stages and Bihu functions draw big crowds in mid-April.
  • Pack light cotton clothes, sunscreen and a compact umbrella.
  • Plan sightseeing for the mornings and keep late afternoons flexible for storms.

Borxa (Mid-June to Mid-August): The Monsoon Paints Assam Green

Borxa is when Assam is at its most dramatic. Monsoon clouds roll in, the Brahmaputra swells to an enormous width, and every paddy field, hillside and tea garden turns a deep, glowing green. Low-lying areas often see floods in this season, which is why wildlife parks close their gates until the land dries out.

For pilgrims, Borxa holds one of the most important events of the year. The Ambubachi Mela at Kamakhya Temple, usually held in mid-June, draws lakhs of devotees and sadhus to Nilachal Hill in Guwahati. To understand why this festival matters so deeply, read our guide to the history of Kamakhya Temple, Guwahati.

The monsoon is also a slow, quiet time to explore the city. Rainy afternoons are perfect for a hot cup of Assam tea, a plate of fresh pitha and a long, lazy lunch while the rain drums on the windows.

Travel tips for Borxa

  • Keep plans flexible and check road and weather updates before any day trip.
  • Pack quick-dry clothing, waterproof footwear and a sturdy umbrella.
  • Focus on Guwahati’s temples, museums and markets rather than long road journeys.

Xorot (Mid-August to Mid-October): Clear Skies and Festive Lights

When the heavy rains ease, Xorot arrives like a deep breath. The sky turns a washed, bright blue, white clouds drift over the hills, and riverbanks fill with swaying kohua grass. Early mornings carry the sweet scent of xewali, the night-flowering jasmine whose small white and orange blossoms cover the ground at dawn.

Xorot is also festival season. Durga Puja, held in the month of Ahin, is one of the biggest celebrations in Assam after Bihu. Guwahati’s neighbourhoods glow with creative pandals, food stalls and cultural shows, and the city stays awake late into the night.

Travel tips for Xorot

  • Reserve rooms early for Durga Puja week, when families and visitors travel in large numbers.
  • Pack breathable clothes plus one light layer, as evenings grow pleasant by October.
  • Go pandal hopping after dark, when the lights and crowds are at their best.

Hemonto (Mid-October to Mid-December): Harvest Gold and Lamp-Lit Fields

Hemonto begins with one of Assam’s gentlest festivals. Kati Bihu, also called Kongali Bihu, falls on the first day of Kati, when the rice is still growing and granaries are often running low. Instead of feasting, families light earthen lamps near the tulsi plant, in the courtyard and out in the paddy fields, praying for a healthy harvest. Some homes also raise an akaxbonti, a lamp hung high on a bamboo pole.

As the weeks pass, the Sali paddy turns gold and the harvest begins. Mornings start with soft mist over the fields, while afternoons stay warm and sunny. This is also when wildlife travel picks up again, as Kaziranga National Park’s visitor season covers the drier months, generally from November to April.

Hemonto also brings Diwali and, on the river island of Majuli, the colourful Raas festival, when Vaishnavite monasteries stage vivid performances from the life of Lord Krishna.

Travel tips for Hemonto

  • Carry a light jacket or shawl for early mornings and late evenings.
  • Plan wildlife safaris for later in the season, and confirm park opening dates before booking.
  • Keep your camera ready for golden-hour views of harvest fields.

Xit (Mid-December to Mid-February): Bonfires, Feasts and Foggy River Mornings

Xit is Assam’s winter, and for many travellers it is the most comfortable time to visit. Days are dry and sunny, nights turn chilly, and a thick fog often rests on the Brahmaputra until late morning.

The highlight is Magh Bihu, also called Bhogali Bihu, the harvest festival held in mid-January. On Uruka, the night before, friends and neighbours gather for a large community feast, often inside temporary huts built from bamboo and hay. The next morning, they light the Meji, a tall bonfire, offer prayers, and share til pitha, coconut laru, curd and jolpan.

Winter is lively for nature lovers too. Migratory birds arrive at wetlands such as Deepor Beel on the edge of Guwahati, and wildlife parks enjoy their busiest weeks. Because the weather is so pleasant, Xit is also the favourite season for weddings, family reunions and open-air celebrations.

Travel tips for Xit

  • Pack warm layers, a jacket and a cap, especially for early safaris and river outings.
  • Book rooms and safari slots well ahead for mid-January and the year-end holidays.
  • Say yes if a local friend invites you to an Uruka feast. It is the best way to feel Magh Bihu.

Bosonto (Mid-February to Mid-April): Blossoms, Colour and the First Tea Flush

Bosonto closes the Assamese year in full colour. Simalu (silk cotton) trees burst into bright red flowers, the air grows warmer, and the countryside wakes up after winter. In the tea gardens, fresh leaves start to appear, and the year’s first flush is usually plucked from around March.

The month of Phagun brings Doul Utsav, Assam’s celebration of Holi, filled with colour, devotional songs and temple festivities. The town of Barpeta, home to a historic satra (Vaishnavite monastery), is especially known for its Doul celebrations.

By the end of Sot, excitement builds once again for Bohag Bihu, and the cycle of six seasons starts over.

Travel tips for Bosonto

  • Pack light clothes with one warm layer for cooler February nights.
  • Visit a tea estate in March or April to watch plucking in action.
  • Pair a Guwahati city stay with a late-season wildlife trip before the parks close for the monsoon.

Which of the Six Seasons of Assam Is Best for Your Trip?

There is no single best season. It depends on what you want from your visit:

  • Wildlife safaris: late Hemonto, Xit and Bosonto, roughly November to April, when Kaziranga and other parks are open.
  • Festivals and culture: Grishmo for Bohag Bihu, Xorot for Durga Puja and Xit for Magh Bihu.
  • Pilgrimage: any season suits a Kamakhya darshan, while Borxa brings the Ambubachi Mela.
  • Green landscapes and photography: Borxa and early Xorot, when the valley is at its most lush.
  • Comfortable city sightseeing: Hemonto and Xit, with cool and mostly dry days.
  • Weddings and family events: Xit, when outdoor and rooftop celebrations feel most pleasant.
