What is Bonalu?
Bonalu is a folk festival honouring the mother goddess Mahakali, celebrated across Telangana — most famously in the twin cities of Hyderabad and Secunderabad. The name comes from bhojanam (a meal): women offer bonam, a pot of freshly cooked rice with milk, jaggery and curd, to the goddess as an act of thanksgiving.
When it falls
Bonalu is held in the Telugu month of Ashada — around July and August, through the monsoon. It unfolds over several weeks, with different temples taking their turn on successive Sundays rather than a single fixed day.
How it's celebrated
Women carry the bonam pots — often decorated and topped with a small lamp — balanced on their heads to the temple, walking in procession to the beat of drums. At the temple the offering is made to the goddess and later shared among family and neighbours.
Pothuraju, Rangam & the procession
The processions are led by Pothuraju, the goddess's brother, played by a bare-bodied man smeared in turmeric with bells at his ankles, dancing to thunderous drums. The next morning brings Rangam, the oracle: a woman standing on an earthen pot invokes Mahakali and foretells the year ahead for the gathered devotees. A grand Ghatam procession then carries the goddess's ornamental pot to the river.
The temples
The season traditionally opens at the Jagadambika temple within Golconda Fort, followed by the Ujjaini Mahakali temple in Secunderabad, the Balkampet Yellamma temple, and the Lal Darwaza (Simhavahini) temple in the Old City of Hyderabad — each with its own celebrated day.
Bonalu follows the lunar calendar, so the exact dates change each year; it falls in July–August. It is one of Telangana's official state festivals. See also Bathukamma, and more of the state's festivals & traditions. Telangana.com is an independent guide, not affiliated with any official body.
