Doha tide times

Doha is Qatar's capital and home to 90% of the country's population, built along the west shore of a shallow bay on the east coast of the Qatar peninsula. The Corniche — a 7-km curved seafront promenade — faces east across Doha Bay toward the horizon of the Arabian Gulf. Behind the Corniche, the high-rise towers of West Bay and the Museum of Islamic Art on its own island define a skyline that has been built largely since the 1990s. The old Souk Waqif and the dhow harbour (Al Mirqab) preserve the older character of a pearl-diving and trading city that predates the petroleum era.

The tidal regime in the Arabian Gulf at Doha is mixed semidiurnal: spring range 1.5–1.8 m, neap range 0.5–0.8 m. Doha Bay is extremely shallow — large portions of the bay floor are 1–3 m at mean water, with extensive intertidal flats that become exposed at spring low water. The tidal current within the bay runs at 0.3–0.7 knots during the ebb and flood phases. The diurnal inequality is pronounced: some days have one dominant tidal cycle (diurnal day), with the secondary tide's height reduced to a few centimetres above or below the main cycle's range.

For the dhow harbour at Al Mirqab, adjacent to Souk Waqif, the spring low water produces the harbour's most photogenic moment and its most operationally constrained. The inner harbour basin is in 1.5–2.5 m at mean water; at spring low water (approximately 0.0–0.2 m CD at Doha), the basin depth drops to 0.0–1.0 m in the shallowest sections and the traditional wooden dhows rest on the bottom. This is not accidental — Gulf dhows are built to sit on the bottom at low tide, and the periodic drying allows hull inspection and maintenance. Dhow-harbour photography at low spring tide, with the vessels grounded and the hull fastenings visible, is distinctively Gulf maritime.

For the Museum of Islamic Art, situated at the tip of its own breakwater promontory in Doha Bay, the tidal range affects the visual character of the approach. At high spring water, the bay around the museum appears fuller and the building seems to rise from open water. At low spring water, the shallow bottom around the approach causeway exposes sand and seagrass flats that reduce the maritime impression but reveal the bay's ecology. Photography of the museum facade from the Corniche is best in the early morning (east-facing) and captures the tidal character of the bay in the foreground.

For boaters and fishermen using Doha's marinas, the spring range of 1.5–1.8 m requires planning on approach to the several marinas along the Corniche and in West Bay. The West Bay Lagoon marina is in a dredged basin with 3.5–4.0 m of water; the approach channel through the bay to the marina is in 2.0–3.5 m. Vessels drawing over 1.5 m should arrive no earlier than 3 hours before high water on spring tides. The bay flats outside the dredged channels have charted depths of 0.5–1.5 m that become exposed or nearly so on spring lows — GPS chart plotters should display tidal correction.

For fishing, Doha Bay and the adjacent Gulf coast are productive for the same Arabian Gulf species as Kuwait: hamour (grouper), zubaidi (pomfret), and kingfish in season. The bay's intertidal flats are productive for bait collecting — ghost crabs and sand worms are available at low spring water. The commercial fish market (Central Market) near the dhow harbour opens early and is the best indicator of what is currently available from the Gulf.

All tide predictions for Doha come from the Open-Meteo Marine gridded model. Timing accuracy is ±45 minutes; height accuracy is ±0.3 m above Chart Datum. Given the very shallow Gulf bathymetry around Doha Bay, the model's gridded approach may underestimate local depth corrections in the bay interior.
