Shenzhen weather by month, at a glance
The whole year in one picture — sky, rain, humidity, temperature and travel score. Click any band to jump to its full chart.
Each stripe is one measure across the whole year, stacked so a single day reads top to bottom. The sky band runs overcast grey on top down to clear blue at the base — more blue means sunnier — followed by the rainfall curve, the humidity band, a temperature strip that tints each stretch of the year by how warm its average high is, and the travel-score line at the foot. Scan straight down any date to read that day across every measure at once; the score climbs highest around mid October to mid February.

How hot and cold Shenzhen really feels
The felt-temperature range through the year — heat index on the day's high (summer humidity), wind chill on the night's low (winter wind). The dashed lines are the plain thermometer; the gap is how much hotter or colder it really feels.

Average hourly temperature in Shenzhen
A compact picture of the whole year, hour by hour: each column is a day, each row an hour, and the color is the modeled average temperature. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
Read left to right for the day of the year and top to bottom for the hour of the day; the color is the modeled temperature, cool blues through to hot reds on the same scale as the other charts. A vertical slice is a single day's swing — coolest just before dawn, warmest in the mid-afternoon — while a horizontal slice follows one hour across the seasons. The darker overlay marks night and the lighter one the twilight around sunrise and sunset. Colors run warmest on July afternoons, near 31°C, and coldest before dawn in January, near 13°C.

Daylight, sunrise and sunset
Hours of daylight through the year, with sunrise and sunset times.
The gold band is daylight — sunrise runs along its lower edge, sunset along the upper — so it widens toward summer and pinches toward winter, with night the dark area above and below. The longest day, around June 11, brings about 13 h 24 min of light; the shortest, around January 1, only 10 h 36 min — a swing of roughly 2 h 48 min.

Humidity comfort
Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.
Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.
In Shenzhen, how humid it feels changes dramatically over the year.
The more humid part of the year lasts 7.2 months, from around March 26 to October 30. The muggiest month is May, when the air feels humid, muggy or worse about 99% of the time.
The most comfortable stretch runs from around October 31 to March 25, and January is the most comfortable month — the air is dry or comfortable 86% of the time.

Wind
Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.
This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.
Across the year, average wind speed in Shenzhen is typically light breeze, near 12 km/h, and varies little with the seasons.
The windier part of the year lasts 5.8 months, from around Oct 27 to Apr 20. The windiest month is December, averaging about 13 km/h (light breeze).
The calmer part of the year runs from around Jul 23 to Oct 26, with September the calmest month at about 10 km/h.

Hazard calendar for Shenzhen
When the seasonal hazards worth planning around — the rainy season, tropical-cyclone risk and dust haze — are active through the year.
Shenzhen sits in the Pacific typhoon belt; the season peaks July–October.
Shenzhen's monsoon runs May–September, when most of the year's rain falls.
Best time to visit Shenzhen
To characterize how pleasant the weather is in Shenzhen throughout the year, we compute two travel scores — one for general sightseeing, one for beach and pool weather.
Around early February, Shenzhen is still near the tail of its best-weather window — great conditions with the peak-season crowds already thinning.
Inferred from the travel-score curve; month-by-month visitor numbers are a planned addition.
The travel score favors clear, rainless days with daytime highs between 18°C and 28°C. Based on this score, the best time of year to visit Shenzhen for general outdoor tourist activities is from mid October to mid February, with a peak score in the last week of November.

What to pack for Shenzhen, by month
Month by month, what's worth putting in the bag — from the temperature range, rain chance, sun and wind. Tap a month for a quick packing note.
For a warm-season trip around July (highs near 31°C), the essentials are light clothes, rain gear and sun protection. In the cold season around January (highs near 19°C), pack a light layer.
In July, Shenzhen sees daytime highs around 31°C and nights near 27°C. Pack light clothes and rain gear. Worth having: sun protection. About 22 days see rain.
Sea temperature near Shenzhen
Average ocean temperature at the nearest coast, month by month, banded into swim-comfort zones — the other half of the beach question.

UV index (midday) in Shenzhen by month
Clear-sky midday UV index through the year, shaded by the WHO exposure levels — how much sun protection each month calls for.
Under clear skies, the midday UV index in Shenzhen peaks around July 13 at about 12 (extreme) — sunscreen, a hat and midday shade are essential. It bottoms out near January 11 at about 6 (high).
The index reaches 3 or more — the level where the WHO recommends sun protection — every month of the year.

Average hourly UV index in Shenzhen
Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.
The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.
UV falls off far faster than brightness as the sun drops, so even in July the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 6.5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Air quality in Shenzhen by month
Average fine-particle pollution (PM2.5) through the year — so you can see which months the air is worst, not just the yearly average.
Air quality in Shenzhen is worst in January — around 27 µg/m³ PM2.5 (moderate), about 2.5× the cleanest month (July, 11 µg/m³).
Seasonal pattern from CAMS reanalysis, scaled to Shenzhen's WHO annual average of 19.4 µg/m³.

Growing season
Shenzhen is frost-free year round — even the coldest nights rarely reach freezing, so there is no start or end to the growing season.

Growing degree days
Growing degree days tally heat above 10°C: each day adds however many degrees its average temperature runs over that threshold, and cold days add nothing. Shenzhen banks about 4,910 degree days a year, and the running total — which growers use to time plantings and predict maturity — climbs fastest around July.

Solar energy
Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.
Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.
Shenzhen receives about 4.4 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 3.4 and 5.5 kWh/m².
The brighter stretch of the year lasts 6.8 months, from around Apr 7 to Oct 31. The brightest month is July, averaging about 5.4 kWh/m² (bright).
The dimmest month is December, down near 3.4 kWh/m² — roughly 37% less than the July peak.
