If Kerala has been on your travel list, Onam 2026 is the perfect excuse to go. The festival peaks on Thiruvonam — Wednesday, 26 August — the heart of a joyful ten-day harvest celebration.
What Is Onam and Why Is It Celebrated?
Onam is Kerala’s most loved festival, celebrated in the Malayalam month of Chingam (August–September). It’s a warm, family-filled celebration of the rice harvest and the homecoming of the beloved King Mahabali.
As the story goes, the kind-hearted Mahabali — sent to the netherworld by Vamana, an avatar of Lord Vishnu — is allowed to visit his people just once a year. Keralites welcome him home with ten happy days of flowers, feasting, and festivities.
When Is Onam 2026?
Mark your calendar: Thiruvonam, the main day, falls on Wednesday, 26 August 2026. The festivities unfold over ten days, starting with Atham on 17 August.
Good news if you’re planning a trip — Kerala has declared four public holidays for Onam 2026:
| Day | Date |
|---|---|
| First Onam (Uthradom) | Tuesday, 25 August 2026 |
| Thiruvonam (Main Day) | Wednesday, 26 August 2026 |
| Third Onam (Avittom) | Thursday, 27 August 2026 |
| Fourth Onam (Chathayam) | Friday, 28 August 2026 |
With these holidays rolling straight into the weekend of 29–30 August, you’re looking at one of Kerala’s longest and most festive breaks of the year.
Onam 2026 Day-by-Day
Every one of the ten days has its own little rituals and charm, all building up to Thiruvonam. Here’s how the 2026 calendar lines up:
| Date | Day | What happens |
|---|---|---|
| 17 Aug | Atham | Celebrations begin; the first Pookalam is laid. |
| 18 Aug | Chithira | Homes are cleaned; the Pookalam grows. |
| 19 Aug | Chothi | New clothes and gifts are bought. |
| 20 Aug | Vishakam | Onasadya preparations begin. |

Avittom (27 August) and Chathayam (28 August) round things off with the Onathappan immersion, more boat races, and Pulikali.
What You’ll See During Onam
Onam turns all of Kerala into a wash of colour, music, and good food. Here are the traditions you’ll fall in love with:
- Pookalam: intricate floral carpets laid at doorsteps, growing larger each day.
- Vallam Kali: thrilling snake boat races on Kerala’s backwaters and rivers.
- Pulikali: the vibrant tiger dance, with performers painted in bold stripes.
- Kaikottikali and Thiruvathira: graceful group dances performed by women.
- Kasavu attire: cream-and-gold sarees and mundu worn across the state.
The Onasadya Feast
If there’s one thing not to miss, it’s the Onasadya — a glorious vegetarian banquet served on a banana leaf, moving from savoury dishes to sweet payasam. A traditional spread can stretch past two dozen items, including:
- Parboiled red rice with parippu (dal) and ghee.
- Sides such as avial, thoran, olan, kaalan, and erissery.
- Pappadam, banana chips, sharkaravaratti, and puli inji.
- Payasam or pradhaman to finish the meal.
Where to Celebrate Onam in Kerala
Onam is celebrated everywhere, but a few spots are extra special. Book your stay early in Kochi, Thiruvananthapuram, or Thrissur — rooms fill fast during the festival.
- Thrikkakara Vamanamoorthy Temple (Ernakulam): the spiritual home of Onam, with special rituals and a famed Onasadya.
- Athachamayam (Thripunithura, near Kochi): the colourful Atham-day procession of floats, elephants, and folk arts.
- Swaraj Round (Thrissur): the city’s spectacular large-scale Pulikali tiger dance.
- Aranmula (Pathanamthitta): the ceremonial Uthrittathi snake boat pageant on the Pampa River.
- Thiruvananthapuram: Kerala Tourism’s official Onam Week, with dates confirmed closer to the festival.
The Nehru Trophy Boat Race at Punnamada Lake in Alappuzha is Kerala’s most famous snake boat event, usually held in August around Onam — check the official schedule before you travel.
Tips for Visiting Kerala During Onam
A little warmth and courtesy go a long way at this much-loved festival.
- Dress modestly; a kasavu saree or mundu is a thoughtful touch.
- Ask before photographing people or rituals.
- Never step on a Pookalam floral design.
- Accept feast servings graciously and avoid wasting food.
- Remove footwear in temple and ritual areas.
And if you’re flying in, it pays to compare fares to Kochi early — prices tend to climb in the days around Thiruvonam.
