Weather in Varanasi in September

A hard month. September is a hard month in Varanasi, and worth planning around. You should expect rain on 16 days of the month, which is more days wet than dry.

September ranks 7 of 12 in Varanasi: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain on 16 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 32.3 °C days and 24.7 °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: 27 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest September day reached 39.6 °C and the coldest night fell to 20 °C, and the wettest single day dropped 102 mm — roughly 70% of the month's rain in one day.

September is moderately variable: 28 mm in the driest year against 425 mm in the wettest, around an average of 146 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 6.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How September sits in the year

Temperatures hold steady either side: 32.9 °C in August, 32.3 here, 32 in October. Nothing about the timing within the month matters much. Rain is the thing that moves: October brings 12 days less of it, so pushing the dates later buys drier weather.

Daylight in September

12.3 hours of daylight, losing 0.7 hours across the month. That is between Varanasi's extremes of 13.7 and 10.6 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 34.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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 Varanasi versus nearby

If Varanasi is one option among several, the nearby comparison is worth making. Patna is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Kanpur is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: September is a compromise. December is 55 points better and is what Varanasi is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
