What to know before you go
Practical intel
Manatee tours depart daily — buy tickets in advance from ICMBio, as groups are limited. Mero Hotel Boutique and Villa Castanheiras are the best local accommodations. Combine the visit with Barra Grande (8 km): Cajueiro da Praia is quieter and cheaper, and works well as a base for both destinations.
About Cajueiro da Praia
Cajueiro da Praia is home to the world's only open-sea manatee monitoring program — guided traditional sail canoe tours observe 10+ mammals in the estuary without disturbing them (motorized boats prohibited). Just 8 km from Barra Grande, the town also has the Cajueiro Rei: the world's largest cashew tree, with 8,810 m² of canopy from a single trunk.

Moon influence and forecast source
Spring Tide — Expect more extreme tides. Great for filling lagoons, be cautious at beaches.
Heights in meters above chart datum. “Mean level” is the average of this day’s extreme heights; it does not indicate depth.
We calculate tides using FES2022 harmonics and calibration data from FEMAR reference stations. Heights use the model’s reference-station baseline, not measurements at each village. For rivers and inland locations, the curve is a coastal tide reference; it does not predict local water levels.

About the visualization and the motion
Motion starts on its own when the visualization is in view.
SpeedThe flow speeds up with the wind speed at the selected hour. At zero wind it stops.
DirectionThe dot on the compass marks where the wind comes from. The lines travel the opposite way.
GustsThe ring shows the difference between wind speed and gust speed. Without valid gust data it disappears.
An illustration only — it does not simulate how often gusts arrive. The summary and the reading use the whole period shown in the chart.
