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 Africa/Tunis local. Folk tradition, not a scientific forecast.

Mahdia occupies Tunisia's easternmost cape on a limestone promontory that juts several kilometres into the Mediterranean. The Fatimid caliphate founded the city in 916 CE as a naval capital, choosing this site because the peninsula's geometry — narrow neck, high seaward cliffs — made the city essentially a fortified island accessible by a single gate. That gate, the Skifa el-Kahla, still stands. It is the only surviving Fatimid gate in Tunisia, and its 25-metre vaulted tunnel cuts through the city wall at near-sea level, opening onto the peninsula's main street on the other side. Stand at the seaward entrance at low water and the sea surface is roughly three to four metres below the threshold. The tide regime here is Mediterranean microtidal: mean range 0.1 to 0.3 m. The astronomical tide contributes almost nothing to water-level variation compared with the effect of synoptic weather systems. The cape's exposure to the open central Mediterranean — southeast and east faces are fully open — makes Mahdia one of the more wave-exposed towns on Tunisia's coast. Northeasterly and easterly storms funnel directly against the Fatimid walls. In recorded history, storm surge events have twice overtopped the seaward bastions, sending water across the lower peninsula during severe autumn and winter gales. These events are exceptional — days to weeks apart in a bad season, years apart normally — but they explain why the Fatimid engineers built the Skifa el-Kahla's threshold high enough to resist moderate surge without flooding the medina interior. The Cap Africa lighthouse marks the eastern tip of the peninsula. The lighthouse structure itself is 19th-century French colonial, built when maritime traffic through the central Mediterranean was growing and the cape represented a genuine navigation hazard. From the lighthouse platform on a clear day, the horizon is open water all the way to the Italian island of Pantelleria, roughly 220 km northeast. Photographers come here at dawn for the combination of lighthouse, cliff edge, and open sea — the eastern exposure means the sun rises directly over the water, and the light quality in the first 30 minutes is useful in any season. North of the peninsula, the fishing harbour handles one of Tunisia's more significant working fleets. The port is best known for the seasonal bluefin tuna fishery. Tunny — the local term for large bluefin (Thunnus thynnus) — are taken using a traditional encircling net system called the mattanza, a word shared with the identical practice that survived into the 20th century in Sicily and Sardinia. The nets are set in a fixed array offshore and progressively constricted over several days, concentrating fish into a final chamber (the camera della morte in the Italian nomenclature). The mattanza at Mahdia is one of the few places in the Mediterranean where this technique still operates at fishing-industry scale. If you are in Mahdia in June or early July and the mattanza is active, the harbour activity in the early morning — boats returning with catch, buyers at the dock, the smell of the fish market on the north quay — is specific to this place in a way that the broader beach and medina experience is not. For anglers working the shore, the seaward walls of the peninsula and the rocky margins below the Fatimid bastions hold the same Mediterranean species as elsewhere on the coast: comber, saddled bream, bogue, and wrasse in the crevices. The cliff-face exposure means swell arrives unimpeded; fishing from the rock shelves below the walls requires calm conditions and attention to sets. The microtidal range means there is no productive tidal window — fish the margins based on sea state and light rather than the tide clock. The beach south of the cape — below the old town's southern wall — is sheltered from northeast swell by the peninsula itself and offers calmer conditions for swimming and paddling. Sand quality is good and the beach is less developed than Monastir's hotel zone. Family use peaks in July and August; outside summer the beach is often uncrowded even on weekday afternoons.
