Fall in Zhuhai feels like a real shift from the steamy, heavy summer into something much more comfortable. Daytime highs start in the upper 80s °F in early September and drop to the low 70s °F by late November, making this season one of the most pleasant times to be outdoors.

Rainfall drops off pretty fast as fall goes on. Early autumn still brings plenty of showers, but by late fall, the skies tend to clear up, and rain becomes rare.

Overview of Fall Climate in Zhuhai
Fall in Zhuhai means cooler temperatures, less rain, and clearer skies compared to the sticky summer months.
You’ll notice the heat and humidity drop off steadily, making it a great season for outdoor activities and travel.

Cloud cover drops from about 75% in September to under 30% by November, so you get more sunny days.
The sea cools too, falling from 29°C (84°F) at the start of fall to 22°C (72°F) by the end.
That change makes the air feel less heavy and tropical.
Daylight hours get shorter fast. In early September, you have about 12 hours and 34 minutes of daylight. By late November, you’re down to 10 hours and 53 minutes.
Sunrise comes later, sunset comes earlier, and that definitely affects how much time you get outside.

Sea Temperature During Autumn
Sea temperatures in Zhuhai cool off as fall goes on, moving from summer heat toward winter chill. This affects how comfortable the water feels and what kind of coastal activities people enjoy.
Monthly Sea Temperature Changes
In September, the average sea temperature is about 29.1°C (84°F). The water feels great for swimming and water sports.
By October, the sea cools to around 27.1°C (81°F). It’s still warm, but you’ll notice it’s not quite as toasty as September.
The drop is slow, and the water stays good for long swims without getting chilly.
In November, the sea temperature lowers to about 23.9°C (75°F). The water feels cooler, especially in the mornings and evenings.
Some folks still swim, but you might want shorter dips or more active water sports to stay warm.
| Month | Avg. Sea Temp (°C) | Avg. Sea Temp (°F) |
|---|---|---|
| September | 29.1 | 84.4 |
| October | 27.1 | 80.8 |
| November | 23.9 | 75.0 |
These shifts show how the region’s subtropical climate lets the sea hold onto summer heat but slowly releases it as fall moves on.
Impact on Coastal Activities
The warm sea in September means you can do just about any water activity, from swimming to sailing.
Snorkeling and diving are great since visibility gets better as rain drops off.
In October, the water is still nice, but a little cooler. Paddleboarding or kayaking feels good, and swimming stays comfortable, though evenings might feel a bit chilly when you get out.
By November, the cooler sea makes long swims less tempting for some. Coastal walks, fishing, and boating get more popular, since the air is less humid and the shore feels great.
If you’re sensitive to cool water, a light wetsuit in late autumn can help you stay in the sea longer and still enjoy the calm, stable conditions.
Rainfall and Rainy Days in Fall
Zhuhai’s fall brings a steady drop in rain compared to summer, but showers still happen. You’ll notice big changes between September, October, and November in both rainfall and rainy days.
Monthly Rainfall Totals
Rainfall drops sharply from early to late fall. September holds onto some monsoon moisture, averaging around 220–250 mm of rain.
October usually falls to about 80–100 mm, and November is much drier with just 30–50 mm.
September feels humid and unsettled, while November is a lot more comfortable for being outside.
Zhuhai’s annual average of 1,800 mm shows just how much rain usually falls outside the fall months.
| Month | Average Rainfall (mm) |
|---|---|
| September | 220–250 |
| October | 80–100 |
| November | 30–50 |
You can really feel the weather shift as autumn moves on.
Frequency of Rainy Days
Rainy days drop along with rainfall. September typically has 12–15 rainy days, making it the wettest month of fall.
October drops to about 7–9 days, and November averages only 3–5 days with measurable rain.
You’re much less likely to have your plans rained out later in the season.
September may still mean carrying an umbrella, but November often brings long stretches of dry, sunny weather.
The drop in rainy days happens as the summer monsoon fades. Winds shift, cooler air moves in, and storms become less frequent and less intense.
Typical Rainfall Patterns
Rain in fall usually comes in short, heavy bursts instead of lasting all day.
September storms can still be tied to tropical systems, bringing intense downpours and sometimes flooding in low areas.
By October, rain is lighter and more scattered, often hitting in the late afternoon or evening.
November brings quick showers or drizzle instead of long rain. The air is less humid, skies are clearer, and you get more chances to enjoy outdoor spots.
Early fall feels less predictable, but late fall brings more stable, comfortable weather with less humidity and fewer interruptions from rain.
Relative Humidity in Autumn Months
Autumn in Zhuhai stays humid, but it gets less sticky compared to spring and summer. You’ll notice the difference between September, October, and November, and that really changes how the air feels and how easy it is to be outside.
Monthly Humidity Levels
Zhuhai’s humid subtropical climate means high humidity year-round. In autumn, it usually ranges between 75% and 82%, with September the stickiest and November the driest.
- September: about 80–82%
- October: about 77–79%
- November: about 74–76%
The air feels lighter as fall goes on. September still feels sticky, especially on warm afternoons, but November is drier and more comfortable.
Even when temperatures drop, humidity affects how you feel outside. A reading of 75% in November won’t feel as oppressive as it does in July, since cooler air can’t hold as much moisture.
Effects on Comfort and Outdoor Activities
High humidity in early autumn makes outdoor sightseeing or exercise feel warmer than the actual temperature. Sweat doesn’t evaporate quickly, so your body can’t cool off as easily.
This happens most in September, when both the temperature and humidity stay high.
October and November get better. Lower humidity makes walking, cycling, and exploring parks much more pleasant.
You might still notice some dampness, but it rarely ruins outdoor plans.
If you’re sensitive to humidity, pack light, breathable clothes for September. By November, you can enjoy cooler evenings with less discomfort, though it’s still smart to carry water since humid air can still add some strain during activity.
Sunshine Hours and Daylight Trends
Fall in Zhuhai brings shorter days and less direct sunshine than summer. You’ll see clear shifts in both the amount of sunlight and the length of daylight from September to November.
Average Daily Sunshine Hours
During fall, Zhuhai gets a moderate amount of sunshine each day. In September, you’ll see about 5 to 6 hours of sunshine daily. This number drops as the season moves along.
By November, the average falls closer to 4 hours per day.
Zhuhai’s subtropical climate brings a lot of cloud cover, especially in early fall. Lingering summer humidity still shapes the weather then.
Later in the season, the air dries out a bit, and the skies clear up more often. Unfortunately, daylight hours get shorter by that point.
Zhuhai gets about 1,738 hours of sunshine in a year. That’s actually less than a lot of coastal cities in southern Europe or Australia.
Fall only adds a small share to this total because the daily averages go down. If you’re planning to be outside, you might want to keep in mind there are fewer bright hours to enjoy.
Changes in Daylight Duration Through Fall
Daylight hours in Zhuhai start dropping off from early September and keep dwindling through late November. In early September, you get about 12 hours and 20 minutes of daylight each day.
By late November, the sun sticks around for just under 11 hours. That’s not a huge difference day-to-day, but it does add up.
You’ll probably notice this shift creeping in, week by week. If you’re outside in the evenings, those earlier sunsets feel a bit more obvious—especially after the autumn equinox hits in October.
For anyone planning outings, keep in mind that evenings get dark much sooner than they do in summer. If you like wandering along Zhuhai’s waterfront or just soaking up the city, you’ll want to head out earlier to catch the best of the daylight.
