Tiruvannamalai in September

September at Coonoor: 14-24°C, monsoon retreating and tea slopes lush at 1,850m. Solid window — quieter than Ooty, toy train running pleasantly.

September at Yercaud: 16-26°C, Eastern Ghats hill station quieter than Nilgiri cousins. Works well — coffee estates lush, orange groves heading into fruit.

September at Hogenakkal: 24-32°C, Cauvery at strong post-monsoon flow, coracle rides through the cascades at their best. Oil massage stalls on the riverbank run all day.

September at Courtallam: 22-30°C, monsoon easing but flow still strong across the 9 waterfalls, herb-infused bathing still in season. Weekends stay packed; weekdays quieter.

September at Ooty: 12-22°C, Queen of the Nilgiris emerging from monsoon haze. Solid window — UNESCO toy train running, crowds thinner than peak summer.

September at Kodaikanal: 12-22°C, monsoon retreating on the 2,133m hills. Solid window — Coaker's Walk views clearing, lake boating runs, peak crowds past.

September at Kotagiri: 13-23°C, oldest Nilgiri station at its quietest with misty tea slopes. Works well — clearer windows arrive week by week.
