Weather in Patna in July

The month to avoid. July is the month most people should skip in Patna. You should expect rain on 24 days of the month, which is more days wet than dry.

July ranks 9 of 12 in Patna: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain on 24 of the month's 31 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. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest July day reached 41.5 °C and the coldest night fell to 24.5 °C, and the wettest single day dropped 128 mm — roughly 46% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 501 mm against 86 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 276 mm average is a reasonable planning figure, not a promise.

Wind is light at 9.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 39.6 °C in June, 34.1 here, 32.7 in August. Nothing about the timing within the month matters much. Rain has already shifted: 9 days more than June had.

Daylight in July

July is at or near the longest days of Patna's year: 13.6 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 33.2 °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.

July in Patna versus nearby

If Patna is one option among several, the nearby comparison is worth making. Varanasi is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Kathmandu is a better bet in July — 7.7 °C cooler, 3 days more rain.

So: July is a compromise. December is 65 points better and is what Patna is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
