Weather in Pune in September
India · 20-year averages, September
Shoulder season. September is shoulder season in Pune — cheaper, quieter, and a genuine gamble. You should expect rain on 22 days of the month, which is more days wet than dry.
September ranks 8 of 12 in Pune: past the worst of the year but short of December, which is the month to book if the dates are open.
Rain on 22 of the month's 30 days, 9 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 89% nothing dries, including you.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest September day reached 33 °C and the coldest night fell to 17.7 °C, and the wettest single day dropped 83 mm — roughly 30% of the month's rain in one day.
September is moderately variable: 72 mm in the driest year against 681 mm in the wettest, around an average of 275 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.
Wind is light at 9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 89% is the real story though — it is the number that decides how the day feels, not the 27.6 °C.
How September sits in the year
Temperatures hold steady either side: 26.8 °C in August, 27.6 here, 28.7 in October. Nothing about the timing within the month matters much. Rain is the thing that moves: October brings 10 days less of it, so pushing the dates later buys drier weather.
Daylight in September
12.3 hours of daylight, losing 0.5 hours across the month. That is between Pune's extremes of 13.2 and 11 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 25.8 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
September in Pune versus nearby
If Pune is one option among several, the nearby comparison is worth making. Mumbai is the weaker option in September — 2.2 °C warmer, 2 days more rain. Virār is close enough to be a coin toss — within a degree on temperature, the same number of rain days.
So: September is a compromise. December is 40 points better and is what Pune is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
