Weather in Pokhara in September

A hard month. September asks something of you. Go in knowing what. You should expect rain on 19 days of the month, which is more days wet than dry.

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

Rain on 19 days, 6 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 88% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 12 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest September day reached 32.9 °C and the coldest night fell to 19.3 °C, and the wettest single day dropped 91 mm — roughly 48% of the month's rain in one day.

September is moderately variable: 60 mm in the driest year against 453 mm in the wettest, around an average of 191 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 5.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 88% is the real story though — it is the number that decides how the day feels, not the 29.6 °C.

How September sits in the year

Temperatures hold steady either side: 30.8 °C in August, 29.6 here, 26.6 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

12.4 hours of daylight, losing 0.8 hours across the month. That is between Pokhara's extremes of 13.9 and 10.4 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 22.8 °C between the year's warmest afternoons and coldest nights. At 1008 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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 Pokhara versus nearby

If Pokhara is one option among several, the nearby comparison is worth making. Bharatpur is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Kathmandu is a better bet in September — 5 °C cooler, 2 days more rain.

So: September is a compromise. November is 52 points better and is what Pokhara is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
