Winter, from December to February, is very mild, with highs around 20 °C (68 °F). The sun, which shines roughly half the time in December, gradually becomes less frequent, while days with cloudy skies, fog, and drizzle become more and more frequent. There may also be windy days. Some days can be pleasantly warm, while in others, the temperature can drop to around 10/15 °C (50/59 °F) even during the day, and the wind can blow, increasing the feeling of cold. Occasionally, it can even get cold, with lows close to freezing and highs around 10 °C (50 °F).

Spring, from March to May, is very mild or pleasantly warm, but the sky is almost always cloudy. In March, a cold wind can still blow, with highs around 13/15 °C (55/59 °F), especially in the first half of the month. By mid-March, with the increase in temperature, the first thunderstorms occur. Already in May, there is sultry heat, with highs around 30 °C (86 °F), even though it's less intense than in the summer months; moreover, the rains become significant.

The long summer, from June to September, is hot, humid and rainy, with heavy showers or thunderstorms, although the sun shines on average for a few hours per day. Daytime temperatures are around 32 °C (90 °F), and the heat is felt because of both the urban heat island effect and the moisture coming from the sea. Luckily, there is widespread use of air conditioning. Usually, the heat remains muggy even at night: lows rarely drop below 25 °C (77 °F), but they can even remain around 27/28 °C (81/82 °F). In the hills around the city and in the districts overlooking the sea, at least, the sea breeze blows. On sunny days, the temperature can reach 35 °C (95 °F) and more. In July, there is often a pause, a period of good weather lasting a week or two.
The probability of typhoons, which bring heavy rainfall and strong winds for a few days, with the risk of flooding and landslides, is highest in this season.

In the short autumn, in October and November, rainfall becomes rare and generally not abundant, and the sun is a bit more frequent than in the other seasons. In the first part of October, the heat can still be muggy, but it gradually becomes more pleasant; in this month, however, and sometimes even in the first half of November, tropical cyclones can still arrive. In November, the temperature is generally pleasant, with highs around 25 °C (77 °F), but cool and windy days gradually become more likely, and sometimes, in the second part of the month, it can get a bit cold.


The amount of sunshine in Shenzhen is not great all year round, and it's scarce from February to April, when the sky is often overcast. In the rainy season, paradoxically, the sun shines more often, since the rains occur in the form of downpours or thunderstorms, which do not last long, so the sun comes back after a while, except when typhoons hit the area. In autumn, the amount of sunshine remains acceptable or improves slightly, however, cloudy days are possible in this season as well.

As mentioned earlier, Shenzhen can be hit by typhoons, tropical cyclones of Southeast Asia. Typically, typhoons occur in this area from June to early November, but they have sometimes affected this area outside of this period, as happened in April 2008 with Typhoon Neoguri (or Ambo) and in May 2006 with Typhoon Chanchu (or Caloy).

Best Time

It's not easy to find the best time to visit Shenzhen. Winter can be a good period, although in the second part, the sky is often cloudy; moreover, it can be windy, and sometimes, though rarely, it can be a little cold. Spring is pleasantly warm, but it's still cloudy, and when the sun becomes a little more frequent, the rains begin as well, then, by May, the air becomes muggy and there is some risk (though still low) of typhoons. In theory, autumn is the best season, but in October, a typhoon can still affect this area, while in November, there can be the first cool and windy days, and at the end of the month, it can sometimes already be a little cold. All in all, the best times are from mid-March to mid-April, and from mid-October to late November.

What to pack

In winter: bring spring/autumn clothes, a sweatshirt or sweater, a jacket, a raincoat or umbrella, and a hat for colder days.
In summer: bring tropics-friendly, lightweight clothing, a light sweatshirt for air-conditioned places, and a light raincoat or umbrella.
