EDITORIAL

About tides at Naples (Bay)

Naples sits at the head of one of the most photographed bays in the Mediterranean, ringed by the Sorrentine Peninsula to the south, Capri at the seaward edge, and the Phlegraean Fields and the islands of Procida and Ischia to the west. Vesuvius dominates the eastern shore and the volcanic geology of the bay reaches under the seafloor and into the inland Campi Flegrei caldera. The tide here is the small Mediterranean signal characteristic of the Tyrrhenian Sea: mean range at Naples is about 0.3 metres, with spring tides reaching close to 0.4 and neaps near flat. Most days the height swing barely registers in the harbour because pressure changes from passing weather systems and wind setup from the local sea-breeze regime each shift water level by similar amounts. The volcanic geometry adds a slow vertical land-motion signal — bradyseism in the Phlegraean Fields, the same phenomenon that flooded the Roman ruins at Pozzuoli over centuries. The bay's coastal cliffs, the deep underwater profile that drops quickly to several hundred metres, and the islands at the seaward edge make the bay much more sensitive to swell, wind, and pressure than to the lunar tide. Fishers working the Capri grottoes, sailors crossing to Procida and Ischia, swimmers at the Sorrento marinas, and snorkellers at the Faraglioni rocks at Capri all read the wider weather pattern more than the tide table. Open-Meteo Marine drives the gridded predictions on this page; ISPRA's Mareografico Nazionale runs the historic Naples gauge.

COMMON QUESTIONS

Tide questions about Naples (Bay)

When is the next high tide at Naples?
The hero block shows the next high tide in the Bay of Naples in local Rome time. The 7-day table covers all four daily extremes — though for the Tyrrhenian Sea the swing is small enough that the secondary high or low often barely registers above the noise.
What's the typical tide range at Naples?
Mean range at the Naples gauge is about 0.3 metres. Spring tides push close to 0.4 metres around new and full moons, neaps drop close to flat. The Tyrrhenian Sea runs the small Mediterranean signal — the open Atlantic tide cannot propagate cleanly through the Strait of Gibraltar and the basin is too small to host its own significant astronomical tide.
What is bradyseism and how does it affect the coast at Naples?
Bradyseism is slow vertical ground motion driven by magma and hydrothermal activity beneath the Phlegraean Fields caldera west of Naples. Over the historic period the Roman market at Pozzuoli has alternated between submerged and exposed as the ground sinks and rises by several metres on decade-to-century timescales. It does not affect daily tide predictions, but the apparent tide range at long-record gauges has shifted noticeably over the centuries because of it.
Where do these tide predictions come from?
Open-Meteo Marine, a global ocean-grid model. Useful for general planning around the bay and the islands, though for the small Tyrrhenian signal the gridded resolution sometimes shows more noise than swing. For authoritative Italian tide data, ISPRA Mareografico Nazionale runs the official gauge network including the historic Naples and Civitavecchia stations.
Is this safe to use for navigation?
No. For piloting in or out of Naples harbour, crossing to Capri, Ischia, or Procida, or working the Sorrentine cliff coast use ISPRA's authoritative tide tables, the Istituto Idrografico della Marina chart products, and the latest Capitaneria di Porto notices. The Tyrrhenian sees occasional Mediterranean meteotsunamis under the right pressure-wave conditions, and those override normal tidal predictions.
