When Is Onam 2026? 🌼

Onam is a ten-day festival in the Malayalam calendar, culminating on Thiruvonam — the most auspicious day. In 2026, Thiruvonam falls on Thursday, 27 August, which places the start of the Onam season (Atham) around 18 August. The days leading up to Thiruvonam each carry their own rituals and significance, so there is plenty of space to celebrate gradually rather than cramming everything into a single evening.

For those who observe the festival closely, the timing is especially pleasing this year: Thiruvonam lands just a day before Raksha Bandhan on 28 August, meaning late August 2026 becomes a genuinely festive stretch for the whole community.

The Story Behind the Festival

Onam celebrates the legendary return of the benevolent Asura king Mahabali to visit his beloved people — a homecoming so cherished that it became an annual tradition of joy, abundance, and gratitude. At its heart, it is a harvest festival, honouring the earth's generosity with flowers, food, and togetherness.

The central rituals include the pookalam (a large, intricate floral rangoli laid fresh each of the ten days), the Onam sadya (a vegetarian feast served on a banana leaf with dozens of dishes), traditional games like tug-of-war and boat races, and the graceful Thiruvathira and Kaikottikali dances. Even if you are experiencing Onam for the first time, the warmth of the celebration makes it immediately welcoming.

Where to Do Puja in Kathmandu 🛕

Onam is not a temple-centric festival in the way that, say, Navratri is — the puja is largely home-based, centred on a simple invocation of King Mahabali and Vamana (an avatar of Lord Vishnu). That said, many families in Kathmandu like to visit a Vishnu temple on Thiruvonam morning to offer flowers and prayers before returning home for the sadya.

Kathmandu is genuinely blessed with Vishnu temples. Budhanilkantha Temple, with its famous reclining Vishnu statue set in a water tank, is one of the most spiritually resonant Vishnu shrines in the valley. Changu Narayan Temple, perched on a hilltop east of the city, is another ancient and deeply atmospheric Narayan (Vishnu) temple — a UNESCO World Heritage Site that rewards an early-morning visit. Ichangu Narayan Temple on the western edge of the valley offers a quieter, more intimate alternative if you prefer to avoid crowds. Sheshnarayan Temple in the southern hills is dedicated to the Shesha-reclining form of Vishnu and draws devotees seeking a more meditative experience.

For those who simply want a peaceful moment of reflection closer to the city centre, Bhimsen Temple and Narayan Temple are accessible options. Arrive early on Thiruvonam morning, carry fresh flowers if you can, and you will find the atmosphere unhurried and welcoming.

Celebrating with Food: The Onam Sadya in Kathmandu

If there is one non-negotiable Onam tradition, it is the sadya — a multi-course vegetarian feast arranged on a fresh banana leaf, eaten with your right hand, in a specific order that balances sweet, sour, salty, and bitter. A proper sadya can include upward of twenty preparations: avial, olan, thoran, erissery, sambar, rasam, parippu, pickles, pappadum, payasam, and more.

Kathmandu's restaurant scene has grown impressively in recent years, and several establishments — particularly those with South Indian or Kerala-leaning menus — put on special Onam sadya spreads during the festival week. The best approach is to call ahead in the first week of August, ask whether they plan an Onam menu, and make a reservation. Sadya seating tends to fill up fast, especially for lunch on Thiruvonam itself.

If you'd rather cook at home, the markets around New Road, Asan Tole, and Kalimati are reliable spots for banana leaves, drumsticks, raw plantain, yam, and coconut — the essential sadya ingredients. Many grocery shops in Maharajgunj and Lazimpat also stock coconut oil and curry leaves regularly.

💡 Desi Insider Tip: The most unforgettable Onam sadyas in Kathmandu happen in private homes and community halls, not restaurants. Introduce yourself to the Malayali community here — often connected through Kerala Samajam-style associations — and if you're lucky enough to score a home invitation, accept it without hesitation. Bring a small box of mithai and arrive on time; the banana leaf waits for no one.

Pookalam: Make Your Own Floral Carpet

A pookalam is a mandala of fresh flower petals laid on the floor near the entrance of a home, renewed every single day for the ten days of Onam. It starts small on Atham and grows more elaborate with each passing day, reaching its grandest form on Thiruvonam.

In Kathmandu, the flowers you need are easier to find than you might think. The flower market near Asan Tole and the stalls along Durbar Marg carry marigolds, chrysanthemums, and a rotating selection of seasonal blooms. Traditional pookalams use flowers like thumba, mukkutti, chethi, and ithi — these specific varieties may be harder to source, but creative substitution is part of the local experience. Aim for bright contrasting colours: yellow, white, red, and pink work beautifully together.

Even a modest five-ring pookalam takes only thirty minutes to lay and brings an immediate festive atmosphere to any home. Encourage children to help — it becomes one of those sensory memories that stays with them for decades.

The Broader Festival Season Around Onam

Onam 2026 lands in the middle of one of the busiest stretches in the festive calendar, which makes late August an especially joyful time to be in Kathmandu. Here is a quick look at what surrounds it:

Nag Panchami on 17 August kicks off the season with the traditional worship of serpent deities — you will see nag paintings affixed above doorways across the city. Raksha Bandhan on 28 August, just one day after Thiruvonam, means the festive energy flows seamlessly from one celebration to the next. Then Krishna Janmashtami arrives on 4 September, followed by Ganesh Chaturthi on 14 September, building toward the grand Navratri and Dashain season in October.

If you are planning a trip back home for Onam or expecting family to visit Kathmandu, build in a few extra days — the energy in the city during this stretch is genuinely wonderful.
