Weather in Chengdu in January

A good month. January is a solid month to be in Chengdu. Highs sit at 11.3 °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 Chengdu: past the worst of the year but short of March, which is the month to book if the dates are open.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Layers, and a genuinely waterproof outer — at 11.3 °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: 12 nights fall below freezing. Across the twenty years measured, the hottest January day reached 18.9 °C and the coldest night fell to -4.9 °C.

January is moderately variable: 3 mm in the driest year against 23 mm in the wettest, around an average of 12 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 5.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

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 Chengdu's year — 10.4 hours of daylight against 14.1 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 — 31.9 °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 Chengdu versus nearby

If Chengdu is one option among several, the nearby comparison is worth making. Chongqing is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Xi’an is the weaker option in January — 4.5 °C cooler, 2 days less rain.

So: January works, with March the better month by 18 points if the dates can move. If they cannot, nothing here should stop you booking.
