Tiruvannamalai in July

July at Hogenakkal: 24-30°C, Kaveri swells and coracle rides run through thundering falls. Solid window — core monsoon flow, spray heavy, check ferry advisories.

July at Courtallam: 22-30°C, peak monsoon flow through the 9 herb-infused waterfalls, the therapeutic bathing season in full swing. Main falls crowded on weekends.
