Onam is Kerala's biggest and most joyful festival - a ten-day harvest celebration of flowers, feasts, boat races and homecoming. In 2026 it runs from 17 to 26 August, with the grand finale, Thiruvonam, on 26 August.
Celebrated in the Malayalam month of Chingam, Onam marks the harvest season and, by legend, the annual homecoming of the beloved King Mahabali. Malayalis believe the just and generous king returns to visit his people, so homes are cleaned, decorated and filled with feasting and joy to welcome him. It is celebrated by all Keralites, across faiths, making it the true festival of the state.
Onam 2026 dates
- Festival period: the ten days from Atham (17 August) to Thiruvonam (26 August 2026).
- Thiruvonam — 26 August — is the most important day, when families wear traditional clothes, complete the Pookalam and gather for the grand feast.
The legend of King Mahabali
Mahabali was an asura king so loved for his fairness and generosity that his kingdom was said to be perfectly happy and equal. As the story goes, Lord Vishnu, in his Vamana avatar, sent Mahabali to the netherworld — but granted him one wish: to return to visit his people once a year. Onam is that homecoming, and the celebrations are a way of showing the king his people are still happy and prosperous.
The rituals & highlights
- Pookalam: intricate floral carpets laid at the entrance of homes, started on Atham and made larger and more detailed each day to welcome Mahabali.
- Onasadya: the spectacular vegetarian feast — traditionally up to 26 dishes served on a banana leaf, from avial and sambar to payasam. It reflects the idea that prosperity is best when shared by all.
- Vallamkali (snake-boat races): Kerala''s famous long boats rowed by dozens of oarsmen to rhythmic songs — the Aranmula and Nehru Trophy races are the most celebrated.
- Pulikali: the vibrant “tiger dance”, where performers paint themselves as tigers and dance through the streets — Thrissur''s Pulikali is legendary.
- Onakkali & culture: traditional games, Thiruvathira dance, and folk performances round off the festivities.
Where to experience Onam in Kerala
- Thrikkakara Temple (near Kochi): the temple dedicated to Vamana, considered the spiritual home of Onam.
- Kochi: big public Pookalam displays, cultural programmes and the festive Onam markets.
- Thrissur: the best place to catch the electrifying Pulikali tiger dance.
- Aranmula & Alappuzha (Alleppey): for the thrilling snake-boat races on the backwaters.
Onam is Kerala at its most beautiful — flowers at every doorstep, a feast on every banana leaf, and boats racing down the backwaters. It''s a festival that welcomes everyone home.
Best time to plan a Kerala trip
Onam (August–September) is a wonderful, colourful time to visit, though it is peak season — book stays well ahead. For calmer weather and the classic backwater experience, September to March is ideal across Kochi, Munnar and Alleppey.
