The beach — Djerba wins, clearly
Djerba's eastern shore from Sidi Mehrez down to Aghir is the gentlest coastline in the country: pale fine sand, a sea-bed that slopes so slowly that children can wade out 50 metres in waist-deep water, and almost no waves. It is the reason so many European families book the island year after year. The water also holds its heat longer — still around 24°C in late October, when the northern coast is cooling off.
Sousse's Boujaffar city beach is wide, gold and genuinely good, but it is a city beach: busy, loud in July and August, with the boulevard's traffic behind it. Port El Kantaoui, 8 km north, is the better Sousse option — calmer, cleaner, marina-side, with the resort polish most visitors are imagining.
Verdict: for pure beach quality and safe swimming, Djerba. For a beach with a city attached, Sousse.
