Anzio tide times

Anzio holds two identities in tension. On the surface it is a resort town 55 kilometres south of Rome — a harbour with fishing boats, seafood restaurants, beaches drawing summer Romans since the 19th century. Beneath that, it is one of the most significant military history sites in Italy: the landing beaches of Operation Shingle on 22 January 1944, where 36,000 Allied troops came ashore in the largest amphibious operation of the Italian campaign. Both identities are simultaneously present and entirely serious.

Tidal range at Anzio is approximately 0.3 metres — consistent with the Tyrrhenian coast south of Rome. The beach environment is exposed, with long-period swell from the southwest arriving with minimal shelter. The harbour provides good protection for small craft but the outer anchorage and beach are open to libeccio conditions. In summer, the morning sea is usually calm before afternoon wind builds.

The American Military Cemetery at Nettuno, 5 kilometres east of Anzio, is the primary memorial site — 7,861 graves in a formal garden on a clifftop 500 metres from the sea. The British equivalent is at Anzio itself. The beach at Anzio town is where the Allied landing craft came ashore; today it is a public sandy beach in the resort town, with no obvious physical demarcation of the event. The Beachhead Museum in Anzio provides the historical context, and the Nettuno cemetery the scale of what happened in the five months between the landing and the May 1944 breakout.

The harbour fish market runs mornings when boats return, concentrated around the Porto Innocenziano. The catch reflects the productive Tyrrhenian fishing grounds off the Lazio coast: sea bass (spigola), sea bream (orata), squid, and mullet in volume; swordfish seasonally. Several restaurants adjacent to the harbour operate the classic porto model — you pass through the market, point at what you want, it appears on the table.

Anzio is also the reputed birthplace of Nero and was the site of a significant Roman villa complex; Caligula was also born here. The remains of the Villa of Nero, partly submerged, are visible from the cape at low water on calm days — another layer on a coast that accrues history the way the Tyrrhenian accrues swell.

Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
