Clima em Pondicherry em setembro

Regulars call September the better half of a two-month stretch, more pleasant than August though still hot and humid, with the southwest monsoon rain arriving as sporadic few-minute showers rather than the continuous rain of a proper wet month. Our row backs the transitional read - 34.7C reading as a real 40C at 75.5 percent humidity, with 104.5mm across 16.6 days - frequent but each fall brief. The month that actually soaks this coast has not started yet: the northeast monsoon, which brings most of Tamil Nadu's annual rain, sets in around the 20th of October and intensifies from there. The sea is 29.5C. The record: 8.8 hours of sun, a 17.2 kph wind and AQI 66.

Regulars are split on just how bad this month gets - some calling it genuinely the hottest stretch of the year, others pointing to the coastal position as real relief compared with inland cities at the same time. Our row backs that hot, genuinely dry read, 34.2C reading as a brutal 40C, over 26.8C nights, with rain minimal at 13mm across 3.6 days and humidity at 76 percent. Regulars are consistent early mornings and late evenings are the only genuinely comfortable windows for sightseeing, with this month also coinciding with Indian school summer holidays, so local family crowds pick up at the same time as the heat. The sea sits at a warm, swimmable 30.3C. The record: 11.3 hours of sun, a 19.6 kph wind and AQI 58.

Pondicherry-forum threads on December weather describe the tail end of the northeast monsoon, still capable of a heavy shower or two but noticeably calmer than the peak of the season a month earlier. Posters call the days warm and pleasant overall, humidity high but manageable with the sea breeze along the promenade, and evenings genuinely comfortable for the long beachfront walks the town is known for. Regulars are consistent that any rain this time of year tends to arrive in a short, intense burst rather than settling in for the day, so an umbrella covers most situations without needing full wet-weather gear. The French Quarter's cafes and heritage streets stay fully in swing regardless of the odd shower. Regulars call December one of the more comfortable months here overall. The record: 28.4C days feeling like a punishing 31C, 22.7C nights, a 27.5C sea, 79 percent humidity and 9 hours of sun.

Pondicherry-forum threads on November travel confirm it sits at the peak of the northeast monsoon, real rain expected and occasionally heavy if a cyclonic system happens to be active offshore. Posters are consistent the rain arrives in spells of three to four days rather than a continuous month-long soak, and genuinely clear stretches with little rain do happen between those wetter runs. One visitor's actual trip logged on-and-off rain, sometimes heavy, but nothing severe enough to derail the itinerary. The standing packing advice is a breathable rain jacket paired with an umbrella rather than heavy waterproof gear, since the heat and humidity make fully sealed rain gear uncomfortable to wear for long. Light, minimal clothing otherwise is the norm regardless of the rain forecast. The record: 29.3C days feeling like a sticky 33C, 23.7C nights, a notably high 301mm across 20.1 days, 82 percent humidity, a 28.9C sea and 8 hours of sun.

January in Pondicherry is warm by day and warm at night, which regulars offer as the specific contrast with north India, where the same month turns genuinely cold once the sun goes. Our row gives 28.6C over 21.8C, reading as 31C at 76 percent humidity. The monsoon here runs October to December rather than in summer, so January arrives just after the rain rather than before it - our row still carries 44.6mm across 6.1 days, the tail of it. It is also peak season, and the advice that follows is to book ahead, because the town is small, French-Indian and popular. The record: 9.9 hours of sun, a 27C sea and AQI 87.
