Question 1

Which season is the wettest in Shenzhen?

Accepted Answer

Summer (June to August) is by far the wettest season in Shenzhen, delivering 1,104.5 mm (43.5 in) of rain in 2025 — more than half of the city's entire annual rainfall.

Across the meteorological summer (JJA) of 2025, June was the single wettest month with 411.3 mm (16.2 in), followed by July at 364.8 mm (14.4 in) and August at 328.4 mm (12.9 in). That summer total accounted for roughly 57% of Shenzhen's 1,935.6 mm (76.2 in) of precipitation for the whole year. The wet months also bring high humidity, averaging around 85% and mean temperatures near 28°C (82°F).

The contrast with the rest of the year is dramatic. Spring (March to May) was the next wettest at 398.6 mm (15.7 in), while autumn (September to November) saw 371.9 mm (14.6 in). The driest stretch was the early-year winter window of January and February 2025, which managed just 42.8 mm (1.7 in) combined.

This pattern reflects Shenzhen's subtropical monsoon climate, when warm, moisture-laden air drives frequent downpours and occasional typhoon activity. If you are visiting Shenzhen and prefer drier, more stable conditions, the late autumn and winter months from November through February are the safest bet, while summer travellers should pack rain gear and plan flexible indoor options around the heaviest showers.

Question 2

How hot does Shenzhen get in summer?

Accepted Answer

Shenzhen gets consistently hot and humid in summer, with average daily highs of **31.5°C (88.7°F)** across the 2025 summer season (June 1 to August 31). The hottest single day in Shenzhen during this period reached **35.1°C (95.2°F)** on June 10, 2025.

Across meteorological summer (JJA), the seasonal mean temperature held at **28.0°C (82.5°F)**, and July was the warmest month at **28.6°C (83.5°F)**. Heat was remarkably persistent rather than extreme: of the 92 summer days, 73 days reached at least 30°C (86°F) as a daytime high, while 17 days climbed to 33°C (91.4°F) or above. Only a handful of days, such as June 4 at 26.9°C (80.4°F), stayed noticeably cooler.

What defines summer in Shenzhen is not record heat but relentless humidity. Average relative humidity stayed near **84.8%** throughout June, July, and August, which makes the real-feel temperature considerably more oppressive than the thermometer alone suggests.

For visitors, this means Shenzhen summers are best handled with light, breathable clothing, frequent hydration, and air-conditioned indoor breaks during the early-afternoon peak. Outdoor sightseeing is most comfortable in the early morning or after sunset, when daytime highs ease. Because the heat in Shenzhen rarely spikes above 35°C but rarely drops below 30°C either, you can expect warm, sticky conditions almost every day of the season rather than occasional heatwaves.

Question 3

When is the best time to visit Shenzhen for good weather?

Accepted Answer

The best time to visit Shenzhen for good weather is late autumn, roughly from October to November, when the city enjoys warm but comfortable temperatures, low humidity, and very little rain. November 2025 stood out as the standout month for travellers.

Based on 2025 weather data, November was by far the driest month in Shenzhen, with just 6.9 mm (0.27 in) of rain across the entire month. Average humidity dropped to 59.9%, the lowest of the year, making the warmth feel far more pleasant. The mean temperature was a mild 21.2°C (70.2°F), with daytime highs reaching up to 31.9°C (89.4°F) and cooler nights dipping to 10.7°C (51.3°F).

October was also excellent, averaging 26.2°C (79.2°F) with only 55.6 mm (2.2 in) of rain. Together, this October–November window delivered warm, sunny, and dry conditions ideal for sightseeing and outdoor activities.

The contrast with summer is striking. During the meteorological summer of June to August 2025, Shenzhen received a soaking 1,104.5 mm (43.5 in) of rain, paired with humidity above 84%. Avoiding these wet, sticky months makes a big difference.

For the most comfortable trip to Shenzhen, plan for the dry autumn season. You'll get plenty of sunshine, manageable heat, and minimal rain disruption, perfect for exploring the city's parks, coastline, and skyline.

Question 4

Which months had the most sunshine in Shenzhen in 2025?

Accepted Answer

The sunniest months in Shenzhen in 2025 were **July, August, and June**, with July leading the year at 293.8 hours of sunshine — about 9.5 hours of sun per day.

Across the full 2025 calendar year, Shenzhen recorded 2,706 hours of sunshine, averaging roughly 225 hours per month or about 7.4 hours per day. The three brightest months all fell in the heart of summer:

- **July 2025:** 293.8 sunshine hours
- **August 2025:** 267.4 sunshine hours
- **June 2025:** 263.6 sunshine hours

Interestingly, these peak-sunshine months were also the wettest, since Shenzhen's summer combines long, strong daylight with heavy monsoon downpours — June alone saw 411mm (16.2 in) of rain. The least sunny month was February 2025, with just 130.0 hours, while dry, breezy November delivered a pleasant 175.8 hours alongside only 6.9mm (0.3 in) of rain.

For visitors, this means that even Shenzhen's rainy summer offers plenty of bright spells between storms, with intense sun and average temperatures near 28°C (82°F). If you prefer reliable sunshine without the downpours, the autumn months of October (227.4 hours) and the drier late-year stretch provide strong sun with far less rain. Overall, 2025 confirms that Shenzhen is a generously sunny subtropical city year-round, with summer delivering the highest raw sunshine totals.

Question 5

How humid is Shenzhen throughout the year?

Accepted Answer

Shenzhen is a notably humid city, with average relative humidity of 75.3% across 2025 thanks to its subtropical coastal climate. Moisture levels swing widely through the year, peaking in the rainy summer and easing in the cooler, drier winter months.

The most humid month of 2025 was June, averaging 85.1% relative humidity, while the driest was January at just 58.2%. That gives Shenzhen an annual humidity spread of nearly 27 percentage points between its dampest and crispest months.

Five months of 2025 stayed at or above 80% humidity:

- May: 81.4%
- June: 85.1%
- July: 84.9%
- August: 84.3%
- September: 82.2%

Across the meteorological summer (June to August), humidity in Shenzhen averaged 84.8%, coinciding with the heaviest rainfall of the year. By contrast, the Jan–Feb 2025 portion of winter averaged a much more comfortable 64.7%, and November dropped to 59.9%.

In practical terms, the high summer humidity makes the heat feel considerably more oppressive, so the warm season often feels "stickier" than the thermometer alone suggests. Visitors planning extended walking, sightseeing, or outdoor exercise will find the late-autumn and winter window (November through January 2025) far more comfortable, with humidity 15–25 points lower than the muggy summer. If you do travel to Shenzhen between May and September, lightweight, breathable clothing and good hydration go a long way against the sustained 80%-plus moisture.
