Valparai in September
Tamil Nadu, India
Leeches thrive in September's wetness, making jungle walks frustratingly itchy rather than enjoyable
Valparai in September is the soft re-opening but with the first fortnight still under SW monsoon influence. Rainfall 250-400mm across 18-22 wet days at the 1193m elevation, most in the first three weeks. Daytime 20-23C, nights 16-18C, humidity dropping toward 85 percent. The 40-hairpin NH183 Aliyar-Valparai climb (60km from Pollachi base) stabilises in the third week — TN PWD closure events drop from 2-3 per week to under 1 per week from Sep 20 onward. Lion-tailed macaque (LTM, IUCN endangered, ~3000 globally) troops at Iyerpadi-Puthuthottam-Sholayar tea estate boundaries become more visible as rain eases. Nature Conservation Foundation (NCF) macaque-watching tours resume on partial schedule late month — full daily tours don't restart until October 1. Great Hornbill juveniles and parents flying together at high visibility on clearing afternoons. Tea estate accommodation returns to advance bookings: TANTEA ₹1,400-2,500, Parry Agro ₹2,400-4,000, Briar Tea Bungalow ₹4,000-7,000. Monkey Falls at year-peak flow. Aliyar Reservoir at near-capacity. October is the cleaner call — same Anamalai green at materially better road conditions.
