Weather in Teni in September

A hard month. September is a hard month in Teni, and worth planning around. You should expect rain on 18 days of the month, which is more days wet than dry.

September ranks 9 of 12 in Teni: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 18 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.7 °C days and 22.4 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 24 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest September day reached 37 °C and the coldest night fell to 19.6 °C, and the wettest single day dropped 44 mm — roughly 34% of the month's rain in one day.

September is moderately variable: 27 mm in the driest year against 252 mm in the wettest, around an average of 128 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 6.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How September sits in the year

Temperatures hold steady either side: 31.4 °C in August, 31.7 here, 30.5 in October. Nothing about the timing within the month matters much.

Daylight in September

Teni sits close enough to the equator that daylight barely moves all year — 12.2 hours in September, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 17.8 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Teni versus nearby

If Teni is one option among several, the nearby comparison is worth making. Munnar is a better bet in September — 11.1 °C cooler, 3 days more rain. Madurai is close enough to be a coin toss — 2.5 °C warmer, 3 days less rain.

So: September is a compromise. January is 37 points better and is what Teni is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
