Zhuhai tide times

Zhuhai occupies the western bank of the Pearl River estuary, directly across the boundary from Macau and linked to Hong Kong by the 55 km Hong Kong–Zhuhai–Macau Bridge — the longest sea-crossing bridge in the world when it opened in 2018. The city is the westernmost of the original four Special Economic Zones designated in 1980. Tidal conditions are mixed semidiurnal with a mean range of approximately 1.0 to 1.2 m above chart datum — modest, reflecting the estuary geometry and the Pearl River's interference with tidal propagation.

The Pearl River estuary at Zhuhai is a complex tidal environment. Freshwater discharge from the Pearl River system (annual mean approximately 10,000 m³/s, peaking at 30,000+ m³/s in June–August flood season) modulates the tidal signal: during high discharge, the freshwater head reduces tidal amplitude in the upper estuary, and salinity at the Zhuhai waterfront drops from 25 ppt in the dry season to near-zero during summer floods. The lower tidal range relative to the open South China Sea coast reflects this interaction.

The Hong Kong–Zhuhai–Macau Bridge (HZMB) crosses the outer Pearl River estuary via a combination of viaduct, artificial islands, and a 6.7 km immersed tube tunnel that passes under the main shipping channel. The bridge carries private cars and cross-boundary coaches (not trucks or public transit); the tunnel section was the most technically demanding element, requiring precise placement of 33 tunnel sections on the estuary bed in water depths of 20 to 40 m with tidal currents of 1.5 to 2.0 knots. The construction required 500,000 tonnes of marine-grade steel. The Hong Kong and Zhuhai boundary ports are purpose-built artificial islands at the bridge's ends.

Zhuhai's coast is characterised by island geography. The city encompasses 146 islands; the most visited is Hengqin Island, now a major development zone co-administered with Macau, containing the Chimelong Ocean Kingdom theme park (the world's largest aquarium by water volume at 48.75 million litres) and the new Guangdong–Macau In-Depth Cooperation Zone. Wanzai on the Hengqin channel is a fishing and seafood village that has survived the development push, with a morning market still supplied by local fishing boats.

The Zhuhai Fishing Girl statue (珠海渔女, 1982) on Xianglu Bay is the city's emblem — a 8.7 m figure of a woman holding a pearl, standing on rocks at the water's edge. The statue has become the symbolic representation of the city internationally.

Zhuhai's coastal amenity is primarily the Lovers Road (情侣路) promenade — a 28 km seafront esplanade running the full length of the city's eastern shore from Jida in the north to Xiangzhou harbour in the south, with views across the estuary to the bridge and to Macau. The promenade is used for cycling, walking, and kite-flying; it functions as Zhuhai's main public open space. Sunset from the promenade looking east across the estuary is the standard Zhuhai photograph.

Tide predictions on this page come from Open-Meteo Marine, a global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
