If you visit Kerala during the late monsoons, get ready to immerse yourself in a once-in-a-lifetime kind of cultural fete during Onam, Kerala’s official state festival.
It is primarily a harvest festival observed in the month of Chingam that marks the beginning of the Malayalam calendar, Kollavarsham. On the Gregorian Calendar, it falls in the month of August-September.
According to the legend, this is when the powerful and benevolent King Mahabali came back from hell to the earth every year to meet his people since being sent to Patal (hell) by Vaman, a dwarf Brahmin avatar of Lord Vishnu. His revisit marks the 10-day-long celebration of Onam since the Sangam period in India.

Pookalam – An elaborate floral map

Pookalam literally translates to flowers (poov) and colour sketches (kalam). It is the beautiful and intricately decorated floral carpet, the laying of which is often seen as auspicious during Onam. It is similar to the Rangoli in North India, only being replaced by pinches of flower petals in various hues.
Women in households team up to decorate the floral map and put their artistic touch to beautify their homes and temple premises. When finished, they lit up lamps and place them in the middle or around the edges in a synchronized manner. Festoons and a miniature pandal (which looks like an umbrella) also make their way to the flower carpet.
Traditionally, this ritual starts on the Atham day (the day of Atham Nakshatra) of the festival with Athapoo. On this first day, the design is small and simple, with only one circular layer using only yellow flowers. They become more circuitous and ornate with each passing day. Kerala’s indigenous flowers and the Dashapushpam, or the ten flowers, are a must-include in the varieties used. In places across the state, Malayalis also take part in the Pookalam competitions.
Vallamkali – Row, row, row your boat

Must visit places in Kerala during Onam
One of the best times to experience Kerala is during the celebration of Onam, a time when the entire state is adorned with festive colours and joyful jamboree. So, here’s a list for you so that you don’t count out the must-visit places in Kerala during Onam and overpass enjoying all the must-have experiences.
Trikkakara Temple
This previous abode of King Mahabali near Kochi is closely linked to the origin of the Onam festival. Legend has it that it was at this precise spot where Lord Vishnu’s fifth Avatar, Lord Vamana, to whom the temple is dedicated, had sent the king to Patal or hell. Therefore, undoubtedly, a visit to this historic temple becomes of prime importance during Onam.
Lord Vamana’s deity is taken out in the procession during the flamboyant Pakalpooram procession. On the last day of the festival, the deity bathing ceremony, also known as the Arattu ceremony, ticks off the 10-day carnival to an end.
Apart from the processions, dance, and musical performances, one of the festival highlights here is the Onasadya grand banquet. People from various religious sects join in the ceremonial spirit and enjoy a sumptuous meal, ending it with the mandatory payasam.
Trivandrum
Down in the South, Thiruvananthapuram, or erstwhile Trivandrum, had been a prominent cultural hub for ages. No festival, including Onam, goes without a boisterous celebration in this city of diverse ethnicity. For the ten days of Onam, Pookalam competitions, theatrical performances, arts, handicrafts fairs, folk dance competitions, etc., pepper the whole city at over 20 locations.

Aranmula
The carnival takes a different turn from the road marching in Aranmula. The waters of the holy River Pamba and the racing boats along its length steal the show during Onam in this picturesque heritage village. Thousands of locals and tourists flock to the banks to witness this snake boat pageantry as rowers turn against each other in the rhythm of the drums and zealous boat songs.
Pay a visit to the Aranmula Parthasarathy Temple, which was the heart of the Pamba Valley civilization. While in the village, don’t leave without the Aranmula Kannady, a unique and spectacular metal mirror showcasing the local craftsmen’s mastery for centuries.
Alleppey
Famous for its backwater cruises, Alleppey is THE place to be if you want to relish Onam celebrations in nature’s lap. It is a nonpareil experience to take part in Pookalam making on a houseboat and gorging on the delectable Onasadya while being afloat amidst the forested lands surrounding the rustic backwaters.
Arrive earlier in August and head out to the Punnamada Lake area to watch one of Kerala’s premier Vallam Kali, the Nehru Trophy Boat Tri Race.
Thrissur
Pulikali, the Tiger Dance, is one electrifying experience in Thrissur. Get a glimpse of the vibrant gathering near Swaraj Round. As locals don tiger attires and mimic tiger movement, the intoxicating performances and reverberating percussion beat infuse the atmosphere with festal vibes. A fun-to-watch event, you can join the revelry of the Tiger Play with scores of locals and tourists on the fourth day.
Onam festival celebration in 2023
For the year 2023, as stated by Kerala’s Chief Minister Pinarayi Vijayan, Onam celebrations will be held from 27 August to 2 September with a number of events.
State-level programs will be held in Thiruvananthapuram, and as advised by the Chief Minister, concerned departments should organise programs in a way that attracts people from outside Kerala.
Moreover, the Chief Minister, at the meeting discussing Onam 2023 celebrations, has further directed the following suggestions:
- the Onam procession will be organised with the participation of various government departments, public sector institutions, cooperatives and local self-government bodies.
- the departments should prepare and present floats, and there should be Onam markets.
- separate vegetable markets should be started, with the Kudumbashree markets being organised.
- food products, including vegetables, shall be given at a minimum price.
- horticorp should procure vegetables from farmers in Vattavada, Kanthalloor, and Wayanad.
- vegetables which are not produced enough in Kerala should be procured and distributed directly from farms and farmer associations in neighbouring states with quality assurance. Inspection should be done to control hoarding, black market etc.
- prominent names in the art and cultural sectors should be featured in the Onam celebrations.
- illuminations would be arranged for a week, and the Tourism department should take the initiative to arrange adequate facilities and ensure the safety of tourists.
- the departments should conduct meetings to ensure that the Onam celebrations are grand and colourful.
