Weather in Xi’an in October

Prime time. October is about as good as Xi’an gets. Highs average 21.7 °C, lows 10.7 °C, and rain falls on 10 days — nothing in the month is working against you.

October ranks 3 of 12 in Xi’an. Only March scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 10 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 34.9 °C and the coldest night fell to 2.4 °C, and the wettest single day dropped 41 mm — roughly 69% of the month's rain in one day.

October is moderately variable: 10 mm in the driest year against 124 mm in the wettest, around an average of 59 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 67%.

How October sits in the year

The month is on the way down: 5.7 °C cooler than September, with November dropping another 6.7 °C. The first week and the last are not the same trip. Rain is the thing that moves: November brings 5 days less of it, so pushing the dates later buys drier weather.

Daylight in October

11.4 hours of daylight, losing 1 hours across the month. That is between Xi’an's extremes of 14.4 and 9.9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 37.4 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

October in Xi’an versus nearby

If Xi’an is one option among several, the nearby comparison is worth making. Wuzhong is close enough to be a coin toss — 3 °C cooler, 6 days less rain. Chongqing is the weaker option in October — 2.1 °C warmer, 7 days more rain.

So: October is effectively as good as it gets here — 6 points behind March, which is inside the margin where the weather stops being the deciding factor and price starts being it.
