Natal tide times

Natal has a semidiurnal, mesotidal regime. DHN/FEMAR records a mean tidal range of approximately 2.6 m above LAT (Lowest Astronomical Tide). Spring tides — occurring around new and full moon — push the range toward the higher end of that figure. The difference is visible on the beach: at low water the foreshore can widen by 30–50 m compared to high tide conditions.

The fort sits on a reef platform that is partially exposed at low tide, which opens up the reef walk and gives you a cleaner view of the structure from the landward side. Visit within 2 hours either side of low water. Check that day's tide table — low water times shift roughly 50 minutes later each day. The fort is also best photographed in the early morning before haze builds.

Yes. Beach buggies north of Natal travel along the strand between the dune line and the surf. At high water the available sand narrows significantly, and some river and creek crossings become deeper. Most operators time the departure to catch low water in the northern section around Genipabu. If you book a full-day tour, confirm with the operator which tidal window they're targeting — it affects both the route and the river crossing logistics.

Loggerhead and hawksbill sea turtles nest along several beaches in Rio Grande do Norte state. The most active protection work is centred further south at Praia das Tartarugas near Pipa, about 85 km from Natal. The TAMAR Project (Projeto TAMAR) monitors nesting in the region; turtle emergence is primarily nocturnal and seasonal (roughly October through March for nesting). Visits to nesting beaches are regulated — contact TAMAR for current protocols.

Tide times and heights shown here are modelled from Open-Meteo Marine, which provides global tidal coverage. Typical accuracy is ±45 minutes on timing and ±0.2–0.3 m on height relative to observed water levels.
