Aadi Perukku 2027

About Aadi Perukku

Aadi Perukku is the Tamil festival of the rising river, held on the 18th day of the Tamil month of Aadi, when monsoon water swells the Kaveri and other rivers. In 2027 it falls on Tuesday, 3 August 2027. Families pray at the riverbank, newly married women renew their thali, and farmers in the delta sow seed.

Perukku means a swelling or rise. By the middle of the Tamil month of Aadi, the southwest monsoon has filled the Kaveri's catchment in Karnataka, the Mettur dam releases water, and the river reaches the delta. Aadi Perukku is the day Tamil families go down to the water to thank it. It is also called Pathinettam Perukku or Aadi Pathinettu, "the eighteenth of Aadi", and in the Kongu region of western Tamil Nadu it is Aadi Nombi.

It is unusual among Tamil festivals in one way: it is fixed by the solar date, not by a star or a lunar day.

Why the date is 2 or 3 August

The Tamil calendar is solar. Aadi begins when the sun enters Karka (Cancer), around 16 or 17 July, and Aadi Perukku is simply the 18th day of that month. Because the sun's entry can fall late in the day, the month sometimes starts a day later, and the festival moves between 2 and 3 August. Drik Panchang for Chennai gave 3 August in 2026 and 2 August for 2028.

What happens at the river

Along the Kaveri the day has a familiar shape, from the first bath to the meal on the bank.

1. Bathe in the riverWomen bathe early, then claim a patch of the bank, clean it and lay a banana leaf.
2. Set out the offeringLamps, betel leaves, areca nut, fruit, flowers, turmeric and camphor go on the leaf, with sweet and plain pongal for the goddess.
3. Pray to the riverThe prayer is to Kaveri as a mother, for water, a good harvest and the family's welfare. Many also worship Amman, or the Saptha Kanniyar, the seven maidens.
4. Renew the thaliA senior married woman of the family ties a fresh thali thread for a new bride. Married women also change their own, praying for a long married life.
5. Float the lamps and garlandsLamps on banana-stem rafts go into the river. Newly married couples float their wedding garlands.
6. Eat on the bankThe family shares kalanda sadam, mixed rice dishes carried from home: lemon, coconut, tamarind, tomato and curd rice.

Unmarried girls pray for a good husband, and in some families women hold a symbolic valaikaappu (baby shower) for the goddess and pray for children. People who live far from a river do the same at a well, a temple tank or a lake. In Tirunelveli and Thoothukudi the prayers are made on the banks of the Thamirabarani.

Srirangam, Hogenakkal and the delta

The best-known gathering is at the Amma Mandapam ghat in Srirangam, Tiruchi. On this day Namperumal, the procession image of Ranganatha from the Srirangam temple, is brought to the ghat and given a ritual bath. A seer, a gift fit for a bride's family to send, is offered to the Kaveri from the temple: silk, a thali and auspicious items, released into the river.

The festival runs the whole length of the river in Tamil Nadu, from Hogenakkal falls in Dharmapuri and the Mettur dam in Salem through Bhavani Kooduthurai, Erode, Kulithalai, Thiruvaiyaru and Kumbakonam to Poompuhar on the coast. At Kolli Hills in Namakkal, women visit the Agaya Gangai falls.

The day is also a farming date. Farmers in the delta choose a good hour on Aadi Perukku to sow paddy and sugarcane that will be harvested in Thai, the month of Pongal. The Tamil proverb "Aadi pattam thedi vithai" tells farmers to seek out the Aadi season for sowing.

When the river is low

The festival depends on the monsoon, and some years the river does not come. In 2026 the Cauvery at Srirangam was dry on Aadi Perukku for the first time since 2017, because Mettur had not released water. Tiruchi set up shower pipes at Amma Mandapam, Thiruvaiyaru put up showers at its ghat, and families placed their offerings on the dry riverbed. The crowd was under half of the year before.

That is worth remembering when you send a wish. In a good year the message is about plenty. In a dry year it is a prayer for rain.

What to write

How to wish someone on Aadi Perukku

An Aadi Perukku wish is about water and plenty: a full river, a good sowing season, a household that grows. Mention the Kaveri, the ghat the family goes to, the mixed rice eaten on the bank, or a new bride's first Aadi Perukku. "Aadi Perukku nalvazhthukkal" is the usual Tamil greeting. In a dry year, a wish for rain and a full river is kinder than a cheerful one.
