Weather in Nanjing in February
China · 20-year averages, February
Shoulder season. February sits in between. You will get good days and you will lose some. Highs sit at 10.5 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
February ranks 8 of 12 in Nanjing: past the worst of the year but short of October, which is the month to book if the dates are open.
Rain on 9 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 10.5 °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: 14 nights fall below freezing. Across the twenty years measured, the hottest February day reached 25.9 °C and the coldest night fell to -13.2 °C, and the wettest single day dropped 32 mm — roughly 50% of the month's rain in one day.
February is moderately variable: 20 mm in the driest year against 121 mm in the wettest, around an average of 64 mm. Roughly two Februarys in three land near that average, and the third does something else entirely.
Wind is light at 10.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, which at 10.5 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How February sits in the year
The month is on the way up: 3 °C warmer than January, and March adds another 5.4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in February
11 hours of daylight, gaining 0.9 hours across the month. That is between Nanjing's extremes of 14.2 and 10.1 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 34.2 °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.
February in Nanjing versus nearby
If Nanjing is one option among several, the nearby comparison is worth making. Hangzhou is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Shanghai is close enough to be a coin toss — within a degree on temperature, 2 days more rain.
So: February is a compromise. October is 34 points better and is what Nanjing is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
