Onam Significance – Why This Festival is Special?

Below are the key reasons that explain why the festival of Thiruvonam is significant in the Malayali community and tradition: 

  • Kerala Harvest Festival: The Onam significance is related a time of hope and prosperity for farmers after the hard work done in the Karkidakam (the month of heavy monsoon). It marks the end of the monsoon and the beginning of the rice harvest season (known as Onakoythu, Chingakoythu, or Kannikoythu).

  • Symbol of Prosperity and Good Times: The Kerala harvest festival, aka Onam, also symbolises abundance, prosperity and the return of good times. Furthermore, it showcases the rich cultural heritage of Kerala.

  • Lord Vishnu’s Vamana Avatar: The Onam also celebrates the 5th incarnation of Lord Vishnu, Vamana, a young dwarf Brahmin. Several ancient texts, such as Vamana Purana and Bhagavata Purana, mention the birth of Vishnu’s Vishwaroopa Trivikrama Vamana on the eve of Onam.

  • Celebrated in Chingam: Onam falls in the first month of the Malayalam calendar (Kollavarsham), Chingam and is the first festival of the year. The festivities begin with Atham, gradually building up to the Thiruvonam onam 2025 main day.

Onam Rituals 2025: How is Onam Celebrated

Onam is celebrated with great happiness and many special customs all over Kerala. These Onam rituals are done throughout the 10-day festival, each having its own meaning and significance. Here is how people celebrate the festival of Onam:

  • Atha Pookkalam

Families and children begin making Pookkalam (flower rangolis) using local flowers such as Thumbapoo, Mukkuttipoo, and Kannanthalli. On the first day, people draw a single flower, then add new colours or rings each day until Thiruvonam. These flower drawings symbolise prosperity and are made to welcome Lord Mahabali.

  • Thrikkakara Appan Worship

Clay idols representing Lord Vamana (Lord Vishnu’s dwarf avatar) and King Mahabali (also known as Thrikkakara Appan and Onathappan) are placed right in the centre of the growing Onam Pookalam.

  • Onakkodi (New Clothes)

Families buy and gift each other new clothes on Chodhi, a ritual called Onakkodi. Men typically wear a traditional attire called Mundu, while females wear Kasavu sarees (creamy white with golden borders), and young girls wear Pattu Pavada.

  • Home Cleaning and Decoration

Not just buying new clothes, but Onam rituals also involve cleaning and decorating homes. This gets them ready to welcome their beloved King Mahabali into their homes.
