When Is Onam 2026? 📅

The Malayalam calendar places Onam in the month of Chingam, and in 2026 the ten days of Onam begin on Tuesday, 18 August (Atham) and culminate on Thursday, 27 August (Thiruvonam). Each of the ten days carries its own name and ritual significance, but three days matter most to most families: Atham, when the first pookalam ring goes down; Uthradom (the ninth day, 26 August), when King Mahabali is said to arrive; and Thiruvonam itself, the day of the grand feast and reunion.

It is worth noting that Nag Panchami falls on 17 August, just one day before Atham, so the week leading into Onam already has a devotional mood across the city.

Puja & Temple Visits in the City 🛕

Onam has Vaishnavite roots centred on the legend of Mahabali and Vamana, but across Thiruvananthapuram you will find every kind of temple marked by the festive spirit. Here are some of the city's Hindu temples where you can attend prayers and seek blessings during the season:

ISKCON Thycaud Krishna Temple, located near Kundarathala Road on the Old NH, naturally centres its Onam observances on Lord Vamana — the avatar at the heart of the Onam story. Morning aarti on Thiruvonam is particularly atmospheric here.

Malayinkeezhu Sree Krishna Swami Temple on Sreekrishna Temple Road is another Vaishnava shrine worth visiting; the quieter suburban setting makes it ideal for families who prefer a less crowded darshan.

For devotees of the Goddess, Kundamanbhagam Bhadrakali Temple on the Kundamankadavu–Peyad Road and Ayanikkadu Sree Bhadrakali Temple on the 8th Stone–Irumba Road both see heightened activity in August, tying the harvest season to the protective energy of Bhadrakali.

Adhiparasakthi Temple on Mylamoodu Road and Idakkulam Devi Temple in Mannamoola are neighbourhood shrines where early-morning visits on Thiruvonam day feel intimate and deeply local.

If you are in the southern reaches of the city, Mahadeva Temple in Karoor and Karoor Mahavishnu Temple, both on Mangalapuram–Pothencode Road, make a natural pair for a morning circuit.

General tip: most temples begin Onam-day special pujas between 5 am and 7 am. Arrive early, wear cream or off-white (the traditional Onam colour), and carry a small offering of flowers.

The Pookalam: Ten Days, One Beautiful Tradition

The pookalam — a floral rangoli laid at the front of the home — is the most visible public art of Onam. The discipline is simple: one ring of flowers on Atham, and one more ring added each subsequent day, until the full ten-ring design blooms on Thiruvonam morning.

Flower markets around East Fort, Chalai and Thampanoor become festive bazaars from Atham onwards. The classic choice is thumba (white Ceylon slitwort), marigold, and the bright yellow murikku, but competitive pookalam makers source everything from rose petals to chrysanthemums. Many apartment societies and neighbourhood associations hold pookalam competitions through the week — check your local WhatsApp group, because these are genuinely joyful community events.

The Onam Sadya: What to Expect on the Banana Leaf

The sadya is the centrepiece of Thiruvonam — a feast of 26 or more vegetarian dishes served on a fresh banana leaf, eaten in a specific order, culminating in the pappadam-and-payasam finale. At home, the preparation usually begins the night before: raw banana, yam, ash gourd, drumstick, and fresh coconut are prepped well in advance.

If you are not cooking at home, restaurants across the city serve special Onam sadya from around Uthradom through the day after Thiruvonam. Look out for sadya menus advertised in your neighbourhood from mid-August onwards. Traditionally you eat with your right hand, seated on the floor if possible, and the leaf is folded away from you when you are satisfied — folding it toward you signals displeasure, a small etiquette detail worth knowing before your first feast as a guest.

💡 Desi Insider Tip: Skip the crowded main-road restaurants on Thiruvonam afternoon and instead look for a neighbourhood home that advertises a community sadya — several residents' associations and cultural clubs in areas like Pattom, Vazhuthacaud, and Nalanchira organise these for a nominal contribution. The food is often more authentic, the atmosphere is genuinely festive, and you will come away with new friends.

Celebrations Right After Onam: The Long Festival Weekend

Onam 2026 runs directly into an extended festive stretch that is unique to this particular year's calendar. Raksha Bandhan falls on 28 August, the day after Thiruvonam — making it natural to celebrate the sibling bond alongside the harvest joy. Families with North Indian roots in Thiruvananthapuram often blend the two occasions beautifully.

Looking a little further ahead, Krishna Janmashtami arrives on 4 September, followed closely by the Kovalam Marathon on 13 September at Grove Beach — a great way to work off those sadya calories — and then Ganesh Chaturthi on 14 September. The August–September window in Thiruvananthapuram is simply one long, layered celebration.

Onam for Families and Children

Onam is among the best festivals for children to be involved in, start to finish. Assign the youngest family member the job of placing the first flower on Atham morning. Let children help source flowers from the market. Enrol them in a school or community pookalam competition — these are everywhere in the week before Thiruvonam and prizes are usually simple but memorable.

For older children and teenagers, the Vallam Kali (snake boat race) tradition is something to look up this year; while major races like Nehru Trophy happen in Alappuzha, local cultural associations sometimes screen them live or organise smaller water events. The legend of Mahabali is also a wonderful story to share: a just king, a clever avatar, and a promise that binds king to people across time — it resonates with any age.
