Tiruvannamalai in August

August at Hogenakkal: 24-30°C, sustained monsoon keeps the falls at full volume and coracles running. Works well — 2,000-year oil-massage tradition stays active.

August at Courtallam: 22-30°C, second monsoon peak feeding all 9 cascades, Saral festival bathing runs through the month. Main Falls gets the thickest weekend crowds.
