Alghero tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Europe/Rome local. Folk tradition, not a scientific forecast.

Alghero is the town on Sardinia that still speaks Catalan. Conquered by Aragon in 1354, the old city was resettled with Catalan colonists so thoroughly that the Algherese dialect survived into the twenty-first century, and the street signs are bilingual. The sea the Aragonese defended is one of the most visually striking stretches of coast in the western Mediterranean: the Capo Caccia headland, 15 kilometres northwest, drops 165 metres straight into water that runs vivid green over limestone, and the Grotta di Nettuno inside it is accessible by a 656-step stairway cut into the cliff or by the regular tourist boat from the old port. Tidal range at Alghero is Mediterranean-typical — 0.2 to 0.3 metres at springs. Wind drives the real water-level variability. The prevailing mistral (maestrale in local usage) comes from the northwest and can build substantial swell on the exposed western coast; Alghero itself sits in a bay that provides some shelter, but the open beaches north and south catch northwest fetch. The Spiaggia di Maria Pia, a long arc of pine-backed sand 3 kilometres from the old city, works best on calm mornings. The Riviera del Corallo — the coral coast named for the red coral once harvested commercially here — runs south toward the Bosa promontory. Diving is the headline water activity. The marine environment around Capo Caccia and the Isola Foradada supports posidonia meadows, red coral colonies, grouper, moray, and occasional sunfish in open water. Visibility routinely exceeds 20 metres. Several dive centres operate from the port district, running trips to the Grotta Verde and the open water passages beneath the cape. The rocky shallows inside Alghero Bay suit snorkellers. Kayaking the Capo Caccia sea caves is possible in calm conditions — a full circumnavigation runs about 22 kilometres from the old port and back. The route passes the stacked rock arch of the Punta Giglio nature reserve, which has been closed to development for decades and shows what this coast looked like before tourism arrived. Timing a cave entry for morning slack conditions is straightforward given the small tidal range. The old city functions as an evening social space in a way that Atlantic walled towns rarely manage. The bastioni — the seventeenth-century Spanish fortifications that replaced earlier Aragonese walls — have been converted into a walkway facing the gulf, and at sunset the light on the water from the Bastione della Maddalena qualifies as genuinely spectacular without requiring any poetic licence. Seafood menus run to aragosta (spiny lobster), seppie (cuttlefish), and bottarga (cured grey mullet roe) grated over pasta. 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.
