Nanhai

Be prepared for any weather surprises during your visit to Nanhai. Below is the current weather summary, charts, and forecasts to help you plan your perfect day.

The climate in Nanhai is best described as humid subtropical, with clearly defined seasons. Overall, the weather is warm and favorable for travel year-round: winters are very mild and comfortable without any frost, while summers are hot and long. Thanks to this temperature range, the city is lush with greenery, creating picturesque landscapes for tourists.

A distinctive feature of the local climate is a pronounced rainy season that lasts from late spring to early autumn. From May to September, the highest rainfall and high humidity occur, with average temperatures often staying around 28–30°C. During this time, rains can be intense, but they are exactly what brings a welcome freshness to the hot summer days.

The driest and most stable period falls in late autumn and winter. From November to January, the number of rainy days is minimal, and the air temperature fluctuates within a pleasant range of 15°C to 21°C. This is considered one of the best times for sightseeing and long walks outdoors, as the heat recedes and the sky remains mostly clear.

The climate in Nanhai is a delight due to the lack of severe cold, meaning you can visit all year round. In winter, even during the "coldest" months — January and December — the average temperature is a comfortable 15-16°C. During the day, the air usually warms up to 19-20°C, and at night it cools down to 11-12°C, allowing travelers to walk around the city without heavy winter clothing.

The summer season brings heat and high humidity. The hottest months are July and August, with average values around 29-30°C. Daytime highs during this time often exceed 32°C, while nights remain tropically warm (around 26°C), meaning you won't feel much of a chill even after sunset.

The most balanced conditions are offered by the transition seasons — April and October. During this time, the average temperature stays at 24-25°C, providing an ideal blend of warmth and freshness. Diurnal temperature fluctuations are moderate: the difference between daytime and nighttime readings is usually about 6-8 degrees, so you shouldn't expect sharp temperature spikes during the day.

Precipitation in Nanhai is unevenly distributed throughout the year, forming distinct wet and dry seasons. Given the region's subtropical climate, where even in the coldest months (January and December) the average minimum temperature stays above +11°C, precipitation falls exclusively as rain. Snow is not characteristic of this area.

The rainiest period occurs during the summer and early autumn. The peak of the rainy season is seen in June and August: these months record the highest number of days with precipitation — up to 25 days a month. May, July, and September also feature high humidity (between 21 and 22 rainy days). Travelers planning a trip during this time should be prepared for frequent rain and should definitely have an umbrella or raincoat with them.

The dry season arrives in late autumn and lasts through the winter. The driest month of the year is December, when it rains on average only 3 days and rainfall levels are minimal (about 1 mm). January and November are also favorable for visiting if you want to avoid the dampness: the number of rainy days during this period ranges from 5 to 7, making city walks much more comfortable.

When packing for Nanhai, it's important to consider the region's humid subtropical climate. For a trip during the summer season, which lasts from May to September, be sure to pack light, loose clothing made of natural, breathable fabrics like cotton or linen. Since these months see the highest number of rainy days (up to 25 days in June and August), a compact umbrella or a light raincoat will be your main companions. Also, don't forget quick-drying footwear that can handle some moisture.

Winter and the shoulder seasons here are quite mild and comfortable: even in January, temperatures rarely drop below 11°C. For travel between November and March, it’s best to stick to the principle of layering. Bring t-shirts, light sweaters, and a windbreaker or a mid-season jacket for evening walks when the air gets cool. In spring, temperatures rise quickly, but so does the frequency of rainfall, so water-repellent outerwear will come in handy.

Regardless of the time of year, your luggage should include comfortable sneakers or flat-soled sandals for long walks around the city and parks. The sun in southern China can be active even through the clouds, so be sure to bring sunscreen and sunglasses. If you are planning a trip during the warmer months, insect repellent won't go amiss, especially for the evenings.
