March in Hogenakkal is the dry-season floor. Daytime 32-35C, nights 22-23C, humidity 55 percent, rainfall under 30mm. The Cauvery river runs at 15 percent of post-monsoon peak. Mettur dam upstream at its annual storage low (the dam-storage cycle bottoms out at end of April before the SW monsoon refills it). The Hogenakkal falls do not exist as a multi-channel cascade — only one or two thin chutes carry water across the wide gorge rock-faces, and most of the gorge floor is exposed rock. Coracle (parisal) rides at ₹150-300 still run but the boatmen now operate within a single narrow channel; the gorge-circling routes are entirely off the menu. The 2,000-year-old oil massage tradition continues at the river-side ghat — ₹300-800 per session. River-bath at ₹50 still happens at remaining flow points but warm-water now (the cool snowmelt-derived Cauvery is gone). Daytime 35C makes the gorge rock retain heat. Stay limited — TTDC ₹800-1,500, riverside lodges ₹500-1,200. The trip-defining experience requires SW-monsoon flow. Skip — push to July when the SW monsoon refills upstream and Mettur dam begins August-September releases.
