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/Antananarivo local. Folk tradition, not a scientific forecast.

Last spring tide on Tue 19 May (range 2.3m). 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.

Toliara — formally Toliara, historically Tuléar — is the regional capital of the Atsimo-Andrefana region and the largest city on the southwest coast of Madagascar. It sits at the head of the Bay of Saint Augustine, a broad, reef-protected embayment where the Fiherenana River meets the Mozambique Channel. The city functions as the hub for everything on this coast: the port handles fuel, cargo, and fishing, and the market distributes produce from the spiny dry forest interior to the fishing villages along the reef. The Bay of Saint Augustine is wide and shallow, sheltered from the open Indian Ocean swell by the barrier reef that runs offshore. The bay's inner margins are sand and reef flat; at spring low water, the flat extends 300 to 500 metres from the shore, exposing coral heads, sea cucumbers, and seagrass beds that are otherwise invisible. The tidal range here is among the most significant on Madagascar's west coast — mixed semidiurnal, with spring range typically 2.5 to 3.5 metres. The drop is visible against the port quay: at low water the pirogues are beached on the mud at the harbour edge; at high water they float at quay level. Port Toliara handles inter-island shipping and is the departure point for speedboat transfers south to Anakao and for sporadic cargo connections to the outer communities along the reef coast. The Mahavatse fishing community on the southern fringe of the city maintains one of the last active pirogue-building traditions on the southwest coast. Traditional outriggers are hewn from a single log — typically from trees sourced inland — and finished with an outrigger float and boom lashed with natural fibre or increasingly with synthetic cord. Watching a hull being shaped by adze is a reminder that the tools and technique have not changed substantially since the Vezo first settled this coast. The Arboretum d'Antsokay lies 12 kilometres northeast of the city centre on the road toward Ihosy. Founded by Hermann Petignat, a Swiss botanist who spent decades cataloguing the endemic plant life of southwest Madagascar, the arboretum now holds more than 900 plant species native to the region. The standout family is the Didieraceae — the spiny succulent trees that look from a distance like something between a cactus and a Dr. Seuss illustration, found nowhere else on Earth except this corner of Madagascar. Allied with them are pachypodiums, endemic aloes, and a remarkable variety of succulents that have evolved to withstand near-zero annual rainfall. The arboretum is accessible at any tide state and makes a logical half-day from town when a low-water reef visit would need to wait. The beach south of the city centre at Toliara runs along the bay shore and is used by local families and fishers. The open-ocean beaches — particularly the stretch north toward Mangily — are better for swimming, as the inner bay can be shallow and stirred by afternoon wind. The reef protects the lagoon from heavy swell, but the southerly trade wind often raises a short chop from early afternoon that makes snorkelling uncomfortable. Morning is generally calmer. Toliara's climate is defined by aridity. Annual rainfall is around 350 millimetres, falling mostly in a concentrated wet season from December to March. The rest of the year is dry, hot, and sunny with a persistent southerly trade wind that picks up through the afternoon. Sea temperatures run around 25 to 27°C at the surface through the dry season and slightly warmer in the austral summer. Humpback whales pass through the Mozambique Channel from July to September; the channel is visible from the higher ground south of the city and from the port, and blow spouts can sometimes be spotted on flat-calm mornings. The practical base for exploring the Toliara Coast, the city has guesthouses, hotels, restaurants, vehicle hire, and fuel. Flights connect Toliara to Antananarivo on Air Madagascar. The university in Toliara has a marine biology faculty and runs ongoing research on the barrier reef system — a resource for anyone seeking current scientific data on reef health in the 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.
