Weather in Guangzhou in April

Shoulder season. April sits in between. You will get good days and you will lose some. You should expect rain on 15 days of the month, which is more days wet than dry.

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

Rain on 15 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29.2 °C days and 19.3 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 14 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest April day reached 36.4 °C and the coldest night fell to 8.6 °C, and the wettest single day dropped 53 mm — roughly 35% of the month's rain in one day.

April is moderately variable: 31 mm in the driest year against 325 mm in the wettest, around an average of 152 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 9.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 26.2 °C in March, 29.2 here, 30.7 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 5 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 Guangzhou's extremes of 13.5 and 10.7 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23 °C between the year's warmest afternoons and coldest nights.

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.

April in Guangzhou versus nearby

If Guangzhou is one option among several, the nearby comparison is worth making. Shenzhen is a better bet in April — 2.6 °C cooler, 2 days less rain. Haiphong is a better bet in April — within a degree on temperature, 5 days less rain.

So: April is a compromise. December is 32 points better and is what Guangzhou is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
