Two main seasons are clearly distinguished in Beihai. Summer, which lasts roughly from May to September, is hot and rainy. During this period, average temperatures fluctuate around 27-29°C, and sometimes higher, while rainfall and the number of rainy days increase significantly, reaching a peak in August. Winter, covering the months from December to February, is, by contrast, mild and relatively dry, with average temperatures around 16-17°C and minimal precipitation. Spring and autumn are pleasant transitional seasons with moderate warmth.

Thus, the general weather pattern in Beihai is a predominantly warm year with a distinctly wet summer season. If you prefer drier and moderately warm weather, ideal for walking and exploring the city, then the autumn, winter, or early spring months are best suited for you. The summer months, however, will delight lovers of true tropical heat and high humidity.

The temperature regime in Beihai is distinguished by its mildness and lack of sharp fluctuations throughout the year. The hottest month is traditionally July, when the average air temperature holds at 29.3°C, and maximum daytime figures can reach 30.8°C.

The summer period, covering the months from May to September, is characterised by consistently high temperatures and palpable humidity. During the day, the thermometer often rises above 30°C, and at night the temperature rarely falls below 25-27°C. Interestingly, daily temperature fluctuations in summer are minimal, amounting to only about 2-4°C, creating a sensation of constant heat. Winter, from December to February, brings pleasant coolness without frost. Average daytime temperatures during this period range between 19-20°C, and night-time temperatures are around 14-15°C. In the winter months, the difference between day and night temperatures is slightly greater than in summer, reaching up to 5-6°C, but sharp drops in temperature are not observed. Spring and autumn delight with particularly comfortable weather, ideal for walks and getting to know the city.

In Beihai, the pattern of precipitation clearly divides the year into two main seasons: relatively dry and wetter. Given the city's warm climate, all precipitation falls primarily as rain. Snow here is an extremely rare phenomenon or entirely absent, as temperatures remain above freezing all year round.

The dry season in Beihai usually lasts from late autumn to mid-spring, covering the months from November to April. During this period, rainfall is minimal. November, December, and January stand out in particular, when the average monthly rainfall is only about 1 mm. December is also the month with the fewest rainy days – on average 5. Although in January, February, and March the number of days with precipitation can reach 9-10, the total volume of fallen moisture remains small (1-2 mm), indicating light or brief rains.

The wet season arrives in May and continues until September, bringing with it an increase in both the total amount of precipitation and the frequency of rains. The peak of the rainy season falls in August: this month sees the highest amount of rainfall – on average 14 mm, and the number of rainy days reaches 27. July is also distinguished by high humidity with 11 mm of precipitation and 24 rainy days. In June and September, rainfall amounts to 10 mm and 9 mm respectively, while it rains for more than 20 days in each of these months. Already in May, an increase in precipitation (6 mm) and the number of rainy days (20) is noticeable. October serves as a transitional period when rain intensity decreases (5 mm of precipitation and 12 rainy days).

When planning a trip to Beihai, it is important to consider its warm and humid subtropical climate. Regardless of the season, you will find light and comfortable clothing useful, as well as comfortable shoes for walking around the city and its surroundings. Sunscreen is necessary year-round, even on cloudy days. Given the changeability of the weather, especially in the transitional seasons, it is wise to use the principle of layering in your clothing: for example, a T-shirt, a light cardigan or shirt, and a windbreaker that can be taken off or put on depending on the temperature.

If your trip falls during the period from May to September, be prepared for hot and humid weather with frequent rains. In this wet season, be sure to pack a light waterproof jacket or raincoat, as well as an umbrella. Clothing made from natural breathable fabrics, such as cotton or linen, will help you tolerate the heat more easily. It also wouldn't hurt to bring insect repellent and perhaps an extra pair of shoes, as one pair might get wet. Do not forget headwear for protection from the sun.

For a trip to Beihai during the drier and cooler period, from October to April, especially in the winter months (December-February), when the average temperature holds around 14-20°C, it is worth taking warmer items. You will need a light jacket, sweater, or fleece top, especially for evening walks or cooler days. During the day, it may be quite comfortable in a T-shirt and light trousers, but in the evening, an extra layer of clothing will be handy. Although there is significantly less precipitation at this time, a compact umbrella or light windbreaker may still be useful in case of rare rains.
