Anamalai Tiger Reserve in June is when the SW monsoon arrives at the Anamalai western face. Rainfall 300-500mm at the 800m Topslip elevation across 18-22 wet days — the western Anamalai face catches significant SW monsoon rain (annual 2,500-4,000mm at higher Valparai elevation, lighter but still substantial at the 800m Topslip base). Daytime 21-25C, nights 17-20C feel mild but constant rain and 95 percent humidity strip visibility. Some safari zones — the Sholayar-end loop, the higher-elevation Karian Shola interior trails — close from early June under TN Forest Department trail-condition protocols. Jeep safari (Forest Department, ₹2,500-4,500 per vehicle, 6:30-9am and 3:30-5:30pm batches) continues on the reduced-zone schedule but with sighting odds dropping to 1-in-30 — wildlife disperses into dense forest cover with water everywhere. The Topslip-Pollachi 35km road (via the Aliyar reservoir) becomes landslide-watch country, closures 1-2 days per week. Bamboo rafting on Parambikulam backwaters suspends through heavy-rain weeks. Karian Shola trekking (₹1,500 per group) suspends. **Closed Monday mornings**.
