Weather in Chongqing in January
China · 20-year averages, January
Shoulder season. January sits in between. You will get good days and you will lose some. Highs sit at 11.9 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
January ranks 7 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.
Rain on 7 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 11.9 °C the difference between a good day and a miserable one is entirely down to what you are wearing.
What the averages hide
Averages flatten a month, and this one hides a few things: 4 nights fall below freezing. Across the twenty years measured, the hottest January day reached 20.6 °C and the coldest night fell to -3.6 °C.
January is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest January on record still delivered 40 mm against 5 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 22 mm average is a reasonable planning figure, not a promise.
Wind is light at 5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, which at 11.9 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How January sits in the year
This is a turning point in the year — December and February sit on opposite sides of it, so the month contains the change rather than following it.
Daylight in January
January sits at the dark end of Chongqing's year — 10.4 hours of daylight against 14 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
January 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, 3 days less rain. Xi’an is the weaker option in January — 5.1 °C cooler, 5 days less rain.
So: January is a compromise. March is 20 points better and is what Chongqing is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
