The tides at Morro de Sao Paulo are of type bi-diurnal, which means that the complete cycle of rise and decline of the water level occurs twice a day. It takes a little over six hours for the tide to swell and about the same for it to return to the previous level, so the cycle starts again, about fifty minutes later daily.
During the weeks of full and new moon phases, there are spring tides. In these weeks, the high tide is higher and the low tide is even lower than normal. The difference between high and low tides is easily greater than two meters during this period.
What occurs during the weeks of half moon phase there are “neap tides”, in which the difference between high and low tide rarely reach a meter.
Aside from this, during the weeks of neap tide, high tide occurs in the mornings, while during spring tide weeks, high tide occurs in the afternoon.

At Morro de Sao Paulo many things depend on the tides: walks on the beach, daytrips and even access to certain places. Wherever you plan on going, be informed of the tides first, and most important…consider the time of your return! It may be very dangerous to find high tide on your way back.

Tide tables are astronomical estimates of the tides, very place-specific. They are available at reliable tourist agencies.
