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 America/Sao Paulo local. Folk tradition, not a scientific forecast.

Next spring tide on Sun 17 May (range 1.0m). Next neap on Thu 21 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.

Bombinhas is a peninsula municipality on the central Santa Catarina coast, projecting southeast into the South Atlantic roughly 60 kilometres north of Florianópolis. The peninsula is narrow enough that beaches face in multiple directions, each with distinct exposure characteristics, and it is compact enough that walking between the main beaches takes 20 to 30 minutes. The tidal regime is semidiurnal with a mean spring range of approximately 1.0 metre — typical for this section of the Santa Catarina coast. Bombas and Bombinhas beaches occupy opposite flanks of the peninsula. Bombas faces northwest across the Zimbros embayment toward the mainland, sheltered from Atlantic swell by the headlands to the south and by the peninsula body itself. The result is typically calm, flat water — a beach for swimming laps parallel to shore, children's play, and watching the morning fishing boat activity from the sand. Bombinhas faces east-northeast, open to the dominant Atlantic swell fetch. When east swell is running, Bombinhas Beach has consistent rideable surf on the beach break at the south end and moderate shore dump across the main stretch. Both beaches share a peninsula, but the conditions on a given day can differ by 1.0 to 1.5 metres of wave height. Mariscal Beach, at the south end of the Bombinhas Peninsula, faces south and is significantly wilder than the main tourist beaches — rockier, less developed, with access requiring either a walk over the headland from Bombinhas or a road via the back of the peninsula. The rocky reef off Mariscal provides snorkelling in 3 to 8 metres of water with visibility of 5 to 10 metres on calm days with settled conditions. The best visibility follows a run of light wind and no recent swell or rain, which reduces turbidity. Winter (June through August), when the tourist load drops and the water settles between cold fronts, often offers better visibility than summer despite lower water temperature. The Reserva Biológica Marinha do Arvoredo lies approximately 10 kilometres offshore — four islands and surrounding sea area under strict biological reserve classification, meaning access requires a research permit and is not open for recreational diving or snorkelling. This is the clearest water in southern Brazil, with visibility reportedly exceeding 20 metres in ideal conditions. Its inaccessibility is part of why it is biologically intact. The sea temperature off Bombinhas is influenced by the cold South Atlantic Current (sometimes called the Falklands/Malvinas Current system in its offshore expression), which makes water here noticeably cooler than the northeast Brazilian coast — typically 18 to 24°C in summer and 14 to 18°C in winter. This limits coral development to isolated rocky outcrops rather than the reef systems of the northeast, but it supports a different species assemblage including abundant octopus, grouper, and sea urchin on the rocky substrates. 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.
