The climate in Jiujiang can be described as humid subtropical, with four distinctly expressed seasons. Winters here are quite cool, with average temperatures around 5-7°C, while summer is hot and humid, when the thermometer often rises above 30°C, especially in July and August.

June stands out as the wettest month, with approximately 11 mm of precipitation and about 20 rainy days. July also remains sufficiently wet. Unlike summer, the autumn and winter months, especially October and December, are characterized by significantly less precipitation. This seasonality in rainfall indicates the presence of a distinct wet period, which is worth considering when planning a trip to Jiujiang.

The summer period in Jiujiang, covering June, July, and August, is distinguished by high temperatures. Already in June, the average temperature exceeds 26°C, and in July and August, it holds steady around 29-30°C. Daytime temperatures in the height of summer often rise above 32°C, especially in August, when it can reach 33°C. Nights also remain warm, with average minimum temperatures around 23-27°C. Considering that the beginning of summer sees a significant amount of precipitation, this period can feel hot and quite humid.

At night, the thermometer can drop to 2.4°C in January, while daytime highs are usually in the range of 8-10°C. Although severe frosts are uncharacteristic, the weather remains quite fresh. Spring and autumn serve as comfortable transitional seasons when the temperature gradually rises or falls. Daily temperature fluctuations throughout the year, i.e., the difference between average maximum and minimum temperatures, average 6-7°C, which is a moderate figure.

In Jiujiang, there is a clearly defined seasonality in precipitation distribution throughout the year. The city experiences periods of increased humidity, which are replaced by drier months. The bulk of precipitation falls as rain. Given the average monthly temperatures, especially minimum values in winter (for example, in January the minimum temperature is 2.4°C), the probability of sustainable snow cover or frequent snowfalls is low, although short-term snow is theoretically possible during the coldest periods.

The most intense precipitation in Jiujiang falls in late spring and the summer months. The peak of the rainy season is observed in June, which brings an average of 11 mm of precipitation and is characterized by approximately 20 days with rain, making it the wettest period of the year. May and July are also distinguished by a significant amount of precipitation (6 mm and 7 mm respectively) and a large number of rainy days (16 and 18 days respectively). Overall, the pronounced wet season covers the period from April to July, when the number of rainy days ranges from 15 to 20 per month.

The dry season in Jiujiang sets in during autumn and continues into early winter. October and December are the driest months, when the amount of precipitation is minimal – only about 1 mm in each of these months. The frequency of rains during this period also decreases noticeably: in December there are on average only 7 rainy days, and in October and September – 8 days each. November is also relatively dry, with 2 mm of precipitation and 9 rainy days. Thus, from September to December, the amount of precipitation and its frequency decrease significantly compared to the summer months.

When planning a trip to Jiujiang, it is important to choose your wardrobe correctly to feel comfortable in any weather. Given the pronounced seasonality of Jiujiang's climate, the principle of layering in clothing will become your best friend. Regardless of the time of year, be sure to take comfortable walking shoes with you, as you will surely want to explore the city and its surroundings. Also, do not forget an adapter for electronics and a portable charger.

In spring (March-May) and autumn (September-November), the weather in Jiujiang is the most pleasant, but changeable. You will need light jackets or windbreakers, sweaters or fleece tops, as well as T-shirts and shirts. An umbrella or a light raincoat will be very handy, especially in spring, when the number of rainy days increases. In summer (June-August), Jiujiang is hot and humid, with temperatures often above 30°C. Choose light, breathable clothing made from natural fabrics such as cotton or linen. Sunscreen, a hat, and sunglasses are mandatory. June and July are the rainiest months, so a sturdy umbrella or a good raincoat is simply essential.

Winter (December-February) in Jiujiang is cool, with average temperatures around 5-7°C. You will require a warm jacket or coat, sweaters, a hat, a scarf, and gloves. Although severe frosts are rare, warm clothing will make your stay more comfortable, especially during walks. Precipitation in winter is lower, but a small umbrella may still be useful for rare rainy or snowy (though unlikely) days. In general, prepare for possible precipitation at any time of the year, but especially thoroughly in late spring and summer.
