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.

very place-specific. They are available at reliable
