Adi Perukku
ஆடி பெருக்கு
July–August · 1 day
Adi Perukku falls on the 18th day of the Tamil month of Adi (mid-July to mid-August), at the peak of the southwest monsoon when Tamil Nadu's rivers — especially the Cauvery — are running full. Tamils traditionally gather at the riverbank in the morning to make offerings to the river: fresh flowers, betel leaves, coconut, and bunches of aval (flattened rice mixed with jaggery, coconut, and savory variants) tied into small floats and released into the water. The festival's full name, Aadi Pathinettam Perukku, literally means "the swelling of Adi-18" — perukku referring to the river's rise. The day is also the start of the Tamil agricultural year's planting decisions, and a day when married Tamil daughters traditionally return to their parents' homes for the blessings of Adi.
What to do
River offering and prayers
EssentialIn the morning, Tamil women traditionally go to the riverbank with offerings — fresh flowers, betel leaves, coconut, and small floats of aval (flattened rice with jaggery and coconut) — and release them into the water as the Cauvery swells with monsoon rain.
Aval and the traditional Tamil meal
EssentialAval — flattened rice — is the signature Adi Perukku food, prepared in multiple sweet and savory variants: sakkarai aval (jaggery and coconut), thengai aval (savory coconut), puli aval (tamarind). A larger traditional Tamil meal with sambar, kootu, and sweet pongal follows.
Daughters returning home
Adi is considered an inauspicious month for new ventures or major decisions; married Tamil daughters traditionally return to their parents' home for the month, and Adi Perukku is the day to receive blessings, gifts, and a meal from their mother.

In the diaspora
Adi Perukku is one of the quieter Tamil festivals in the US diaspora — without a major community gathering for most cities. Tamil Sangams in the Bay Area, New Jersey, Atlanta, and Houston occasionally organize a small riverbank or lakeside observance, but for most families the day is kept at home. A simple version: cook a few Tamil dishes (sambar rice, kootu, sweet pongal, the festival's iconic aval in two or three preparations), tie a small offering of flowers and aval in a banana leaf, and visit any local body of water — a lake, a creek, a botanical pond — to release it. Battery-powered floating diyas substitute for oil lamps where local fire codes restrict open flames on public water.
