Weather in Chongqing in October
China · 20-year averages, October
A good month. October works. It is not the peak, but nothing about it fights you. You should expect rain on 17 days of the month, which is more days wet than dry.
October ranks 5 of 12 in Chongqing: past the worst of the year but short of March, which is the month to book if the dates are open.
This is persistent light rain rather than storms: 17 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. 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 °C and the coldest night fell to 7.1 °C, and the wettest single day dropped 58 mm — roughly 59% of the month's rain in one day.
October is moderately variable: 42 mm in the driest year against 248 mm in the wettest, around an average of 98 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.
Wind is light at 4.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.
How October sits in the year
The month is on the way down: 5.6 °C cooler than September, with November dropping another 5.2 °C. The first week and the last are not the same trip. Rain is the thing that moves: November brings 8 days less of it, so pushing the dates later buys drier weather.
Daylight in October
11.5 hours of daylight, losing 0.9 hours across the month. That is between Chongqing's extremes of 14 and 10.3 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 30.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
October in Chongqing versus nearby
If Chongqing is one option among several, the nearby comparison is worth making. Chengdu is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Xi’an is a better bet in October — 2.1 °C cooler, 7 days less rain.
So: October works, with March the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
