Wind conditions: Normal wind northwest, frequency 13.4%; Subnormal wind northeast, frequency 11.0%; Winter Normal wind northwest, summer Normal wind southeast-east; Strong wind northeast, northeast-north, maximum wind speed is 38 m/s and 37 m/s, respectively. The average number of wind days over 6 years is 32 days, 15 days over 7 days and 6 days over 8 days.
Precipitation: There is abundant rainfall in this area, with an average annual rainfall of 158 days. May to June is the rainy season every year. There are storms brought by typhoons from July to October. The rainfall in September accounts for 25% of the whole year, and the rainfall in winter is less.
Precipitation characteristics: annual average precipitation of 1411 mm, monthly maximum precipitation of 243 mm, daily maximum precipitation of 145 mm, annual average precipitation of more than 25 mm precipitation days of 11 days.
Temperature: The annual average temperature is 16.3 C, the extreme maximum temperature is 39.4 C, the extreme minimum temperature is - 10 C, the maximum monthly average temperature is 28.1 C (July), and the minimum monthly average temperature is 4.3 C (January).
Ice Conditions: Ningbo Port does not frozen and open to navigation all year round.
Tides: Irregular semidiurnal tides. The annual average maximum and minimum tidal levels are 3.1 m and 1.43 m for Ningbo Port, 2.19 m and 1.16 m for Zhenhai Port, 2.9 m and 1.12 m for Beilun Port, respectively. The annual average tidal range is 1.74 m for Ningbo Port, 1.71 m for Zhenhai Port and 1.82 m for Beichang Port.
Tidal Current: The tidal current of Yongjiang River flows along the river course, and its velocity is generally 1-2 knots. In case of flood discharge in the upper reaches of Yongjiang River, the maximum ebb current can reach 2.5 knots.
Tide level and velocity will have a certain impact in strong winds. The tidal current in Beilun Port is mostly reciprocating flow. The designed flow speed of the 200,000-ton Ore Wharf is 1.50 m/s of high tide, 298 degrees of low tide, 2.0 m/s of low tide and 114 degrees of low tide.
Waves: Ningbo and Zhenhai Port Areas are all inland rivers without waves. Beilun Port Area is surrounded by Zhoushan Archipelago as a natural barrier with small waves and no need to build breakwaters.
Navigation information
Channel: Ningbo Port has two entry channels: North Channel, through Yongjiang Estuary, Qiliyu Island, Dahaoshan to Yangtze Estuary, through 25,000 tons of ships. The South Channel, which is imported from the shrimp gate of Zhoushan Islands, reaches Beilun Port Area directly through the Luotou Channel and Jintang Channel. Except for the shallow section with a depth of 17.6 meters, which is about 3 kilometers outside the Shrimp Gate, the water depth of the South Channel is more than 20 meters. Ships of less than 150,000 tons can enter and leave freely, and ships of 200,000 tons can wait for tides to enter the port.
Ningbo Port has radar navigation stations in Daxie, Shitou and Shushrimp Ship Ships to navigate all-weather.
There are five light posts and four lighthouses in total. Four lighthouses are situated
Tangnaoshan (30 20 1 N / 120 58 01 2 E)
Fishy Brain (30 degrees 20'49.1 N/121 degrees 51'32.4 E)
Taiping Mountains (30 degrees 04'59.5 N/121 degrees 49'16.1 E)

Ningbo Port is located in Yongjiang Estuary, Zhejiang Province. Zhoushan Archipelago is the natural barrier in front of it, and Ningshao Plain is the hinterland behind it. It has convenient land and water transportation and the waterway is not frozen all the year round. Ningbo Port is composed of six major ports: Beilun, Zhenhai, Ningbo, Daxie, Panshan and Meishan. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport. There are 191 production berths, including 39 large deepwater berths above 10,000 tons. The largest is 250,000-ton crude oil terminal, 200,000-ton ore unloading terminal, the sixth generation international container berth and 50,000-ton liquid chemical berth. In 2004, the throughput of goods exceeded 220 million tons, second only to Shanghai. Container throughput reached 4.457 million standard boxes, up 44.4%, ranking fourth in the country. Ningbo Port has opened to more than 560 ports in more than 90 countries and regions in the world. It mainly deals in handling, storing and transferring of imported iron ore, domestic and foreign trade containers, crude oil products, liquid chemical products, coal and other bulk cargo. |
