Weather in Shenzhen in December

Prime time. December is about as good as Shenzhen gets. Highs average 21.4 °C, lows 14 °C, and rain falls on 4 days — nothing in the month is working against you.

December is the highest-scoring month of the twelve. The nearest rival is January, and the month at the other end of the year is July.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average December reaches 30 °C. Across the twenty years measured, the hottest December day reached 27.7 °C and the coldest night fell to 3.9 °C, and the wettest single day dropped 102 mm — roughly 408% of the month's rain in one day.

This is the volatile part. December rainfall has ranged from 0 mm to 138 mm across the twenty years measured — a 138 mm spread around an average of 25 mm. The average is real but almost no individual December looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 15.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How December sits in the year

Temperatures hold steady either side: 25.6 °C in November, 21.4 here, 20.1 in January. Nothing about the timing within the month matters much.

Daylight in December

December sits at the dark end of Shenzhen's year — 10.8 hours of daylight against 13.5 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 22.1 °C in December — comfortable for a proper swim. The sea peaks at 29.3 °C in July and bottoms out at 20.3 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

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.

December in Shenzhen versus nearby

If Shenzhen is one option among several, the nearby comparison is worth making. Guangzhou is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Haiphong is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: December is the answer for Shenzhen. If it is booked out or priced out, January is the next best thing at 1 points behind, and July is the month to keep off the shortlist.
