Portoferraio, Elba tide times

Tidal range at Portoferraio is approximately 0.3 m above Lowest Astronomical Tide — one of the smallest in Italy. The naturally enclosed harbour geometry reduces even this modest signal further inside the anchorage. Ferry services from Piombino (the most frequent crossing, roughly 30–60 minutes) operate on clock schedules independent of tidal state. Berth depth in the main ferry terminal comfortably exceeds vessel draft throughout the full tidal cycle. Captains adjust approach for wind set and prop wash off the quay walls, not for tide height.

Tidal currents around Elba are extremely weak — typically under 0.2 knots even at open coastal headlands. There is no meaningful slack-water window to target for diving here. The dominant planning factors are sea state (swell from south-west in libeccio conditions, chop from north-west maestrale), underwater visibility (best in late spring and early autumn, reduced after storms), and boat-traffic density in summer. The geological diversity of Elba's seabed — transitions from granite to schist to serpentinite within a single site — makes many dives visually exceptional regardless of tidal timing.

A full circumnavigation of Elba covers roughly 147 km of coastline. Tidal variation (0.3 m range) is not a meaningful planning factor for beach landings or headland timing. The dominant variables are wind (afternoon maestrale accelerates along the north coast, libeccio creates fetch on the south-west), the exposed western cape (Capo Sant'Andrea, Capo d'Enfola) where swell wraps around, and boat traffic density in summer around the major anchorages. A clockwise circuit starting from Portoferraio typically benefits from calmer morning conditions on the exposed western leg.

Napoleon arrived at Portoferraio on 4 May 1814 and spent nine months on Elba before escaping to France on 26 February 1815. His residence, the Palazzina dei Mulini, sits above the harbour inside the old town walls and is open to visitors. The Forte Falcone and Forte Stella above the harbour entrance were part of the Medici defensive system that predated Napoleon's tenure by centuries, though he repaired and garrisoned both during his stay. The harbour's wine-bottle shape — visible from the fortresses above — made it militarily and commercially attractive long before the Napoleonic period.

Tide predictions on this page come from Open-Meteo Marine and carry an accuracy of approximately ±45 minutes on timing and ±0.2–0.3 m on height in normal meteorological conditions. At Portoferraio, where the total astronomical range is only around 0.3 m, a 0.2–0.3 m model uncertainty is a large fraction of the signal itself — meaning small-scale height details carry limited precision.
