Natural condition
Wind conditions: there are more southeast winds from April to August every year, and more northeast winds from September to March next year. Tropical cyclones mostly occur in May to November. The wind force is generally 6-9 and gusts can reach 10-11 levels.
Precipitation: The annual average precipitation is 1720 mm, mostly concentrated in April to August, accounting for about 60% of the annual precipitation.
Fog condition: There is occasional fog in late winter and early spring, but it lasts for a short time. The average fog days are 25 days per year, mostly between dawn and 9:00 a.m., and the sunrise usually dissipates.
Temperature: The annual average temperature is 21.9 C, the highest temperature is 38.7 C, and the lowest temperature is 0 C.
Tide: It is an irregular semi-diurnal mixed tidal port with the highest tidal level of 3.87 m and the lowest tidal level of - 0.24 m, with an average tidal difference of 1.64 M.
Tide: Reciprocating along the river. The tidal current velocity is 0.77-1.03 m/s and the ebb current velocity is 1.29 m/s.
Waves: Guangzhou Port is nearly 100 km away from the Pearl River Estuary. Waves are gradually dissipated by the influence of riverbed, topography and water depth. The port area basically belongs to an inland river port. The waters in other areas are generally 1-2 km wide, the widest is 3 km, and the wind waves are not very large. Generally, no protective structures are considered, only the influence of waves should be considered in the design of hydraulic structures.
Guangzhou Port is located at the northern end of the Pearl River Delta, at the confluence of the east, West and North rivers of the Pearl River Basin, 145 kilometers from the sea. From the Pearl River Estuary to the port, the order is Humen Outer Port Area, Xinsha Port Area, Huangpu Port Area and Inner Port Area. There are 643 berths for large and small wharfs, including 460,000-ton berths. Guangzhou Port is easy to sail, 35,000 tons of ships can go directly to Huangpu Port Area. Huangpu Port is 17 kilometers away from Guangzhou and has a wide water area. Its harbour conditions are superior and it has direct river-sea access. Maritime transportation is connected with inland river transportation, railway transportation and highway transportation, and it has good natural harbour conditions in all directions. Huangpu Port now has 123 berths, including 5 container berths of 35,000 tons and 22 berths below 10,000 tons. It ranks ninth in the world. In 2003, port throughput reached 191 million tons, ranking among the top ten ports in the world. Container throughput is 2.54 million. From January to October 2004, the throughput of foreign trade goods was 173.32 million tons, an increase of 24.1% over the same period last year. Guangzhou Port is the largest comprehensive port in South China. International maritime transport reaches more than 300 ports in more than 80 countries and regions. Every spring and autumn, China Import and Export Commodity Fair is held in Guangzhou. Export commodities are mainly sold to 154.4 million ports. Countries and regions, the main export commodities are agricultural and sideline products, textile products, heavy industrial products, industrial products, etc. The main import commodities are machinery, steel, non-ferrous metals, photographic equipment, instruments, textile, chemical raw materials, medical and health care equipment. |
