Kerala: The vibrant festival of Onam, celebrated with elaborate floral arrangements (Pookalam), traditional attire, and cultural rituals, is set to unfold across Kerala from August 26 to September 6, 2025. The festival culminates on Thiruvonam, September 5, this year falling on a Friday, promising a long weekend of festivities and homecomings.

The legend behind Onam

Onam commemorates the annual visit of King Mahabali, a benevolent ruler whose reign was marked by prosperity and equality. According to Hindu mythology, Mahabali was sent to the underworld by Lord Vishnu’s avatar, Vamana, but was granted permission to return once a year to visit his people. This return is celebrated as Onam, symbolising unity, gratitude, and cultural heritage.

In Kerala, Onam also marks New Year’s Day and the harvest season, making it a festival of both mythological and agricultural significance.

The 12-day festival calendar

Onam unfolds over 12 days, with each day featuring unique rituals and activities:

  • Atham (August 26, 2025): The festival begins with creating Pookalam—intricate floral carpets outside homes. Preparations include house cleaning, festive shopping, and family prayers.
  • Subsequent Days: Families engage in cooking, cultural events, and community activities. Each day has specific rituals, keeping tradition alive.
  • Thiruvonam (September 5, 2025): The highlight of the festival, marked by grand feasts (Onasadya), traditional dances, boat races (Vallamkali), tiger dances (Pulikali), folk performances like Kathakali, Thiruvathira, Kummattikali, and elephant processions. Families welcome King Mahabali’s spirit with prayers and offerings.

Puja rituals and cultural celebrations

Onam’s religious observances include:

  • Temple visits and Nivedyam offerings
  • Aarppu Vilikkukal: Male family members perform rhythmic shouts to mark the formal beginning of Onam
  • Onasadya: A feast of over 20 dishes served on banana leaves, symbolising community bonding and inclusivity

Significance of Onam today

Onam is more than a harvest festival. It represents Kerala’s rich cultural heritage, community spirit, and social inclusivity. The festival encourages setting aside social barriers, bringing people together at a common table. Tourists from around the world also participate, experiencing the mythology, traditions, and cultural vibrancy of Kerala.

Why 2025 Onam is special

With Thiruvonam falling on a Friday, 2025 promises a long weekend for extended homecomings and celebrations. Families across cities and countries are planning reunions, practicing cultural performances, decorating homes, and preparing traditional feasts. The extended break ensures people can fully immerse themselves in the joys, rituals, and festivities without the usual rush, making this year’s Onam particularly memorable.
