Coorg in October is when the Western Ghats hill district returns to full operations. Daytime 23-26C at 1170m, nights 16-18C, humidity dropping toward 75 percent, rainfall 200-350mm — northeast monsoon overspill from Tamil Nadu hits mostly as 1-2 hour evening showers in the first fortnight. The headline date is Cauvery Sankramana (Tula Sankramana, October 17 annually — the day the Cauvery river is believed to emerge spontaneously from the kundike pool at Talacauvery, marking the river's spiritual birthday) — 50,000+ pilgrims converge on Talacauvery (44km from Madikeri, the river source at Brahmagiri hill 1276m); Bhagamandala (40km, triveni sangam) sees secondary pilgrim flow. Plantation walks at year-second-greenest after the SW monsoon flush. Coffee bushes at peak ripening — Robusta cherries at red-bunch visibility, Arabica development behind. Abbey Falls (5km, 70ft drop, ₹15), Iruppu Falls (Brahmagiri border with Wayanad), Madikeri Fort, Omkareshwara Temple (1820), Raja's Seat (1175m sunset viewpoint) all on full schedule. Tata Coffee Plantation Trails, Coffee Day Estates, Evolve Back, Old Kent Estates all run guided tours ₹500-1,500/person.
