Onam in Kerala 2026: 10-Day Celebrations, Traditions, Food & Events

Posted on Wednesday, August 26th, 2026 by Kamal Kishor Leave a Comment

Onam is Kerala’s grandest festival. It’s not a single-day affair but a 10-day celebration that begins with Atham and peaks on Thiruvonam.

During these days, homes bloom with Pookalam floral carpets. Families gather for the legendary Sadya feast. Streets come alive with cultural performances. And the backwaters turn into racing arenas for Vallam Kali snake boats.

Each day brings something new. Here’s what makes the Onam celebration in Kerala so special.

What are the main traditions of Onam in Kerala?

Onam in Kerala brings together traditions that happen at home, in neighborhoods, and across Kerala’s public celebrations. Here’s a brief look at the customs you’ll see most often:

Part of the celebration	What happens
Onam Pookalam	Families create floral designs outside their homes
Onakkodi	People wear new clothes bought for the festival
Onam Sadya	A large vegetarian feast is served, usually on a banana leaf
Family gatherings	Relatives come together and visit one another
Games	Tug-of-war, swings and other traditional games bring people outdoors
Vallam Kali	Snake boat races take place on Kerala’s waterways
Pulikali	Performers dressed and painted as tigers dance through the streets
Cultural programmes	Music, dance and traditional art forms become part of the festivities

When Is Onam in Kerala?

Onam follows the Malayalam calendar, so dates shift each year. In 2026, Thiruvonam, the main day, falls on August 26. The 10-day celebration begins on August 16 with Atham.

But don’t limit your plans to just August 26. Major events like Pulikali in Thrissur (August 29) and the Aranmula Boat Race (August 30) happen after Thiruvonam too. 

Why is Onam celebrated in Kerala, and why does it last for 10 days?

The history of Onam goes back to the legend of King Mahabali – a ruler so beloved that his people still await his return. According to legend, King Mahabali ruled Kerala with remarkable generosity. His kingdom is traditionally described as a place of prosperity, equality, and contentment.

But Mahabali was a daitya, and his growing power made Indra, the King of the Gods, uneasy. Indra and the devas therefore turned to Lord Vishnu for help.

Vishnu came to earth as Vamana, a young dwarf Brahmin. He approached Mahabali during the yagna and made a simple request: three paces of land. Mahabali, bound by his code of generosity, agreed without a second thought.

Vamana began to grow. His first step covered the earth. His second covered the heavens. For the third step, Mahabali bowed his head and offered it to Vamana. Vishnu placed his foot on the king’s head and sent him to Patala, the underworld.

Moved by Mahabali’s devotion, Vishnu granted him a boon: he could return to his people once every year. That homecoming is what Onam celebrates.

What happens on each day of Onam?

The 10 days of Onam each have their own traditions and preparations. Here’s what happens as the festival moves from one day to the next.

Day 1 – Atham: The Festival Begins

Atham Onam marks the beginning of the Onam celebrations. Families begin by preparing their homes and laying the first Pookalam. This initial floral carpet, called Athapoo, is small and simple, usually made with yellow flowers. Over the next nine days, it will grow into an elaborate design.

Atham also brings the famous Athachamayam procession to Tripunithura, near Kochi. It’s a spectacular parade with caparisoned elephants, folk performers, and vibrant floats. In 2026, it takes place on August 16.

Day 2 – Chithira: The Pookalam Grows

The Pookalam gets another layer of flowers. Homes are cleaned and decorated, while families continue getting ready for the celebrations ahead. As the days pass, the floral design grows along with the excitement around the festival.

Day 3 – Chodhi: Time for New Clothes

Chodhi is when festive shopping kicks off. Families buy onakkodi, new clothes for the occasion. Women shop for Kasavu sarees with gold borders. Men pick out traditional Mundus. Children get new outfits too.

Day 4 – Vishakam: Sadya Preparations Begin

Vishakam is considered highly auspicious. Families start buying vegetables, coconut, spices, and other ingredients needed for the Onam Sadya. The kitchen now becomes part of the action. 

Day 5 – Anizham: The Boats Take Centre Stage

Anizham brings the boats into the picture. This day is associated with Vallam Kali, Kerala’s famous snake boat races. Long, cobra-shaped vessels hit the water. Rowers practice in rhythm. The backwaters begin buzzing with energy. The Onam boat race in Kerala is one of the most anticipated events of the festival.

Day 6 – Thriketa: Family Time Takes Over

By Thriketa, the festival is at its peak. Families visit relatives. Many travel back to their ancestral homes. The Pookalam grows larger. Conversations, laughter, and shared meals become more common.

Day 7 – Moolam: Celebrations Move Outdoors

Moolam brings more activity into neighborhoods and communities. Cultural programs, traditional games, music, and smaller Sadya gatherings become more visible.

Day 8 – Pooradam: The Festive Build-Up

Pooradam is when the king’s presence starts to be felt. In some traditions, clay figures associated with Mahabali and Thrikkakara Appan are placed as part of the Pookalam and household observances.

Day 9 – Uthradam: The Final Preparations

Uthradam is the final preparation day for many families. Shopping is finished, ingredients are brought home, gifts are arranged, and the kitchen gets ready for the next day’s feast.

Did you know? Uthradam is often referred to as First Onam, as families finish their preparations and get ready to welcome Mahabali on Thiruvonam.

Day 10 – Thiruvonam: The Main Celebration

And then comes the day everyone has been preparing for. Families rise early, take a ritual bath, and dress in their Onakkodi. The Pookalam is complete, a vibrant carpet of flowers at the entrance. The kitchen hums with the final touches of the Sadya. Relatives begin arriving.

The day revolves around food, family, and celebration. The Onam Sadya is served on banana leaves. After the feast, traditional games fill the afternoon. Some families visit temples. Others simply enjoy each other’s company. This is the day Mahabali finally returns to his people.

If you’re planning to travel from Delhi, Mumbai, Chennai, or Kolkata, you can easily book your flights to Kerala to join these celebrations.

What does an Onam celebration look like at home?

You don’t need grand public events to experience Onam. For most Malayalis, the real celebration happens at home.

The morning of the Onam family celebration starts with everyone in their new clothes. Someone is finishing the Pookalam outside. The kitchen buzzes with Sadya preparations. Relatives trickle in. Conversations grow louder. Children’s anticipation builds; games come after lunch.

Then comes the Sadya. After the meal, the celebrations continue with games, music, or simply sitting together and talking. There’s no rush. The day is meant to be savored.

It’s easy to forget this home-based side of Onam when you see only the boat races and public events. But it’s the family gatherings that keep the festival personal and meaningful, year after year.

What do people eat during Onam?

Onam Sadya – the meal everyone waits for

If there is one dish, or rather, one entire meal that defines Onam, it is the Sadya. The Onam Sadya is a vegetarian feast served on a banana leaf, with rice at the center and a spread of curries, vegetables, pickles, chips, and sweets arranged around it.

What is served in an Onam Sadya?

A traditional Sadya can have over 20 dishes. The banana leaf is laid with the narrow end to the left. Rice takes the center. Curries, pickles, and sides are arranged around it. Here are some of the classics:

Dish	What it adds to the Sadya
Avial	Mixed vegetables cooked with coconut and a mild seasoning
Sambar	Lentil-based vegetable curry
Olan	A mild coconut-based preparation usually made with vegetables and coconut milk
Thoran	Vegetables cooked with coconut
Pachadi	A sweet or tangy side dish
Pickles	Sharp, spicy accompaniments
Banana chips	Crisp slices served as a snack
Papadam	A crunchy accompaniment
Payasam	The sweet finish to the meal

Depending on the setting, a Sadya can range from 9 to over 30 dishes. Every home and region adds its own touch.
