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 Indian/Mauritius local. Folk tradition, not a scientific forecast.

Next spring tide on Wed 13 May (range 0.6m). Next neap on Sat 09 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.

Mahébourg is a coastal town of roughly 15,000 on the west shore of Grand Port Bay, facing west-southwest into a sheltered lagoon backed by the offshore reef system. It is the principal town of the Mahébourg District and the largest settlement on the southeast coast. The Mahébourg Waterfront Promenade — a 1.5 km paved esplanade along the bay — fronts the town, built in 2010 on reclaimed land and running from the central market north to the small boat harbour at Mahébourg Port. Grand Port Bay holds a specific place in naval history: on 22–27 August 1810, a Franco-Mauritian fleet under Vice-Admiral Duperré defeated a British squadron attempting to land at Mahébourg, sinking three British frigates and capturing a fourth. The Battle of Grand Port was the only naval defeat of the British during the Napoleonic Wars to be inscribed on the Arc de Triomphe in Paris, and the National History Museum at Mahébourg (housed in a colonial mansion on the waterfront) presents the original cannon, ship's logs, and charts from the engagement. The museum is worth 90 minutes of any coastal itinerary on the southeast. The tidal regime at Mahébourg is semidiurnal — two highs and two lows daily — with spring range 0.8–1.0 m. Neap range 0.3–0.5 m. The Grand Port lagoon is notably shallower than the northern Mauritius lagoons; the inner reach between the promenade and the main reef channel is 0.5–1.2 m at mean water level. At low spring water (the full 0.9–1.0 m spring range), the inner lagoon can drop to 0.0–0.3 m in the shallowest reaches adjacent to the promenade. Local fishing boats carrying outboard motors in 0.4–0.6 m draft require the flood tide — or at minimum the mid-tide level — to transit from the small harbour out to the main reef channel without touching bottom. The lagoon at Mahébourg is wide (3–4 km to the outer reef) and the view from the promenade across to the offshore islands — Île aux Aigrettes and the distant peak of Île aux Fouquets — is one of the more expansive coastal views on the island. Île aux Aigrettes, 850 m offshore and accessible by boat from Mahébourg Harbour, is a managed island coral cay where the Mauritian Wildlife Foundation runs the native flora and fauna restoration programme: pink pigeons (Nesoenas mayeri), Aldabra giant tortoises, and the native Mauritian skink all present in a forest that is being returned to its pre-human composition. Boat trips to Île aux Aigrettes depart from the pontoon at the south end of the promenade, twice daily at approximately 09:30 and 13:00. Advance booking is required. For shore anglers, the Mahébourg Waterfront Promenade and the sea wall at the southern harbour are active fishing points, particularly at dusk and dawn. The incoming tide brings mullet and juvenile trevally into the shallow lagoon margins; the outgoing ebb concentrates fish in the channels between the shallow lagoon floor and the deeper boat channel. Night fishing with bait on the bottom targets barracuda and larger trevally. Crab collection (Mauritian swimming crab, Portunus pelagicus) in the seagrass beds at low tide is a local tradition at the southern end of the bay. The Mahébourg waterfront market (Bazar de Mahébourg) operates on Mondays, the main weekly market day in the town. Fresh fish is landed at the small harbour and sold at the market stalls adjacent to the promenade from 06:00. The best fish selection is before 08:30 on market mornings; by 09:30 the premium catch is distributed to restaurants and buyers. Predictions for Mahébourg on this page come from Open-Meteo Marine, a gridded global ocean model; accuracy is typically ±45 minutes on timing and ±0.2–0.3 m on height. The Mauritius Oceanography Institute (MOI) at Albion publishes authoritative harmonic tide predictions for Mauritius.
