Hawar Islands tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Asia/Bahrain local. Folk tradition, not a scientific forecast.

Next spring tide on Wed 20 May (range 1.3m). Next neap on Sat 23 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

The Hawar Islands are a group of small islands at the southern end of Bahrain's territory, separated from the Qatar peninsula by a narrow channel. The main island is Hawar Island itself — about 5 kilometres long and 1 kilometre wide — with several smaller islets and exposed coral heads making up the rest of the group. The waters around them are persistently shallow: the southern Gulf here reaches depths of only 10 to 15 metres even in the deeper channels, and large areas of seagrass and coral flat are exposed on spring low tides. This shallow, warm, seagrass-rich environment is why the Hawar Islands hold one of the largest remaining dugong populations in the Arabian Gulf. Estimates put the Bahrain dugong population at 300 to 400 individuals, with the Hawar Islands and the adjacent Dawhat Salwah bay (the channel between Hawar and the Qatar coast) forming the core habitat. Dugong feed on seagrass — particularly Halodule and Halophila species — and the shallows around Hawar support extensive seagrass beds. The animals are generally visible from the surface when they come up to breathe, roughly every 5 to 8 minutes. Boat-based watching is the standard approach: the channel waters east of Hawar Island and the shallows north of the smaller islets are the most consistent areas. The tidal range at Hawar is approximately 1.5 to 2.5 metres on spring tides — the full southern Bahrain mixed semidiurnal range. At low spring water, the tidal flats on the western side of the island chain expose 0.5 to 1.0 kilometres of flat. This exposure is significant for wading birds: the flats are feeding habitat for Sooty gull, Western reef heron, and Kentish plover year-round. The Socotra cormorant colonies on several of the smaller Hawar islets are among the largest in the world — this species breeds colonially and the Hawar population numbers in the tens of thousands during the breeding season (November through February). The islands' political history shaped access. Qatar and Bahrain disputed sovereignty over the Hawar Islands from the 1930s through the 1990s; the dispute was referred to the International Court of Justice, which ruled in 2001 principally in Bahrain's favour — Hawar and the main group went to Bahrain; the small Janan Island went to Qatar. The border in the Dawhat Salwah channel is the national boundary. Qatar nationals require Bahraini permission to enter the channel; the practical effect on civilian boat traffic is that the waters very close to the Qatar coastline are avoided. Access from mainland Bahrain is by boat from the southern coast — typically from Zallaq or the southern marinas. The crossing takes 20 to 40 minutes depending on the departure point and vessel. There is a small resort on Hawar Island; independent visitors arrive by private or chartered boat. No permanent civilian settlement exists on the islands other than the resort and associated facilities. For photographers, the combination of dugong, Socotra cormorant colonies, and the exposed tidal flat at low water provides a range of subjects. The flat light in the two hours after sunrise is optimal for both wildlife and landscape work. The cormorant breeding colony on the smaller islets is most active from November through February and can be photographed from a boat kept at a respectful distance of 100 metres or more. The seagrass beds around the Hawar Islands support not only dugong but an associated community of species dependent on the same habitat: green turtle feed on seagrass and are present around the islands year-round; the shallows hold a range of reef fish including parrotfish, which contribute to seagrass ecosystem maintenance. The overall ecological productivity of the area — driven by seagrass, tidal exchange, and the relative absence of heavy fishing pressure inside the protected zone — is high by Gulf standards. A half-day boat trip from southern Bahrain covering dugong watching, seabird observation on the smaller islets, and the low-water tidal flat on the western side is one of the more complete wildlife experiences available in the Persian Gulf region. Predictions on this page come from Open-Meteo Marine, a gridded 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.
