Eravikulam in September is the soft re-opening. Rainfall drops to 400-600mm across 16-18 wet days, mostly the first fortnight. Daytime 18-22C at the 2000m elevation, nights 12-14C, humidity easing toward 80 percent. The southwest monsoon retreats from the Western Ghats by September 20-25; Kerala Forest Department resumes regular Rajamala viewing zone operations from week three (online booking eravikulam.kerala.gov.in, ₹125 adult, 7am-4pm gate, bus shuttle ₹30). Trail conditions on the shola grasslands remain muddy through the month — leech encounters possible alongside the bus-shuttle path. Anamudi (2695m) escorted climb permits begin reissuing from late September after the Rajamala range office certifies trail safety. The Kanan Devan Hills tea estates at peak monsoon green flush. Nilgiri Tahr on the grasslands at year-greenest backdrop. NH85 Kochi-Munnar (130km via Adimali) stabilises with closure events dropping to under 1 per week from mid-month. Onam tail keeps Munnar town shops at light hours through the first week. Stays in Munnar town (15km) at year-low rates: luxury ₹5-8k, mid-bracket ₹3-5k, homestays ₹1,500-2,500. October is the cleaner call.
