Traveller notes on Ooty in December
Other months in Ooty
Forum posters cite roughly 15cm of rain and about 15 rainy days as typical for September in Ooty, with daytime temperatures around 26C and nights around 20C, alongside intermittent showers rather than sustained downpours. Posters consistently describe the last week of September as a genuine lull in rainfall, coming as the southwest monsoon withdraws and before the northeast monsoon picks up around October 10th - posters specifically recommend late September into early October for that reason, combining full sightseeing access with thinner crowds. Posters describe the overall feel as similar to mid-August, pleasant with occasional light drizzle rather than heavy rain. Posters generally rate September as a good, visitable month for Ooty, monsoon timing notwithstanding.
March and April are the forum's best travel window for Ooty, and March carries a specific advantage: it is peak exam season in India, so the hill station is noticeably less crowded than in its other good months. Days run near 22°C with nights down to about 12 — mild rather than cold, but a layer earns its place — and rain on under six days. Regulars suggest Coonoor as a base if the hills themselves are the point, two hours away, with Mudumalai's wildlife within reach of both.

Nilgiris peak-season e-pass

Mountain railway reservations
