Weather in Shenzhen in April

A good month. April works. It is not the peak, but nothing about it fights you. Highs average 26.6 °C, lows 21.1 °C, and rain falls on 13 days — nothing in the month is working against you.

April ranks 7 of 12 in Shenzhen: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain on 13 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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: the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 32.1 °C and the coldest night fell to 12.7 °C, and the wettest single day dropped 55 mm — roughly 53% of the month's rain in one day.

April is moderately variable: 12 mm in the driest year against 221 mm in the wettest, around an average of 104 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 12.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How April sits in the year

The month is on the way up: 2.8 °C warmer than March, and May adds another 2.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain is the thing that moves: May brings 6 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

12.7 hours of daylight, gaining 0.6 hours across the month. That is between Shenzhen's extremes of 13.5 and 10.8 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 23.9 °C in April — 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

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.

April in Shenzhen versus nearby

If Shenzhen is one option among several, the nearby comparison is worth making. Guangzhou is the weaker option in April — 2.6 °C warmer, 2 days more rain. Haiphong is close enough to be a coin toss — 2.1 °C warmer, 3 days less rain.

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