Hammamet tide times

Hammamet sits at the western curve of the Gulf of Hammamet, sheltered to the north and east by the long arm of Cap Bon peninsula and facing northeast toward the open gulf and the Ionian Sea beyond. It was one of the first North African resort destinations to reach a European audience — Paul Klee and André Gide both stayed here in the early 20th century, drawn by the light, the medina, and the coast. The beach strip that runs south from the old medina kasbah toward the newer Yasmine Hammamet resort development is the longest in Tunisia, and the position on the western gulf face gives it a particular quality in summer: the morning is glassy, the thermal sea breeze builds from the north by midday, and by late afternoon it has scrubbed the heat off the sand.

The tidal regime at Hammamet is roughly semidiurnal and microtidal. Mean astronomical range is 0.2 to 0.5 metres — essentially the same regime as Sousse to the south, since both stations lie in the same Gulf of Hammamet basin. Spring tides near new and full moons push toward the upper end of that range; neap tides at the quarter moons compress the swing to around 0.2 metres. The practical beach experience at Hammamet is almost entirely wind-driven. The Gregale — the northeast wind that funnels down from the Ionian basin — pushes directly into the gulf from the northeast in autumn and winter, generating wave setup on the Hammamet shore that can raise observed water levels 20 to 40 centimetres above the predicted tide. During those conditions the main beach is not calm. The summer Tramontane from the north and northwest skims across the top of the Cap Bon peninsula and arrives at Hammamet as a lighter coastal wind that keeps the mornings flat and generates the afternoon sea breeze that keeps beach temperatures tolerable.

The old town kasbah at Hammamet sits directly on the seafront, the ramparts running down to the beach at the southern edge of the medina. The small fishing harbour below the kasbah operates a handful of traditional wooden boats targeting sea bream, octopus, and squid in the nearshore shallows. This is not a scale of fishing operation where the tide table drives much scheduling — the range is too small to generate meaningful harbour current, and the fishermen read wind and sea state first. But on calm summer mornings, the outgoing fish market at the harbour below the kasbah walls, the light from the east over the gulf, and the boats going out before seven make a scene that rewards the early start.

Swimming conditions at Hammamet are best from June through September. The beach shelves gently — the 1-metre depth contour runs 30 to 50 metres offshore in many sections — and the bottom is sandy with occasional seagrass patches. At low water in the microtidal range the change in depth over the beach face is small, 0.2 to 0.4 metres across the whole swing, so the difference between high and low water is visible in the dry sand strip but does not meaningfully change swimming depth for adults. Children and paddlers in shallow-draught boats will notice the low-water phase more: the seagrass patches are closer to the surface and some sections get ankle-shallow over the inner bar.

Yasmine Hammamet, the purpose-built resort zone 5 kilometres south of the old medina, has a marina and a long artificial beach. The marina is a sheltered, calm-water environment with none of the Gregale exposure of the open gulf face. Paddleboarders and kayakers using the marina launch have flat water available on almost any summer morning. The beach at Yasmine Hammamet faces slightly more eastward than the old-town beach, catching the sun from a lower angle in the early morning and staying in shade slightly earlier in the evening.

Photographers working Hammamet have access to two different scales of subject. The kasbah and medina wall above the beach are best in the hour after dawn, when the morning light catches the ramparts from the northeast and the fishing boats are already out on flat water. The Yasmine Hammamet marina at dusk — the terrace cafes, the moored yachts, the last light on the western face of the Cap Bon ridge in the background — is a different kind of image entirely: more resort, less history, but the light holds for longer in the evening than at the old-town beach.

Tide predictions on this page come from Open-Meteo Marine, a global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height. For a coast with a mean range of 0.2 to 0.5 metres, that uncertainty is a large fraction of the total signal. The Office National de la Météorologie and the Agence Nationale des Ports are the authoritative sources for coastal and tide data along the Tunisian coast.
