Navigability index · South Coast
Indicative only: the same bulletin reads differently in a fishing boat, a cruising yacht or on a kite. It does not replace the official bulletin or your own judgement on site.
Small boat: waves, gusts and short chop all count.
Sailboat or motor cruiser: a gale sets the limit.
You need wind, but steady. Check it isn't blowing offshore: it would carry you out to sea.

Specific conditions by locality on this coast
Other coastal zones
Tunisia's south coast, from the Gulf of Gabès to the Libyan border, is the warmest and calmest area in the country. The sea here is shallow (less than 50 m), which warms it quickly in summer (up to 29°C at Djerba) but also makes it rougher under southerly winds (ghibli).
Frequently asked questions
The sea at Djerba is the warmest in Tunisia: 24-26°C in June, 27-29°C in July-August, still 24°C in October. In winter it drops to 14-16°C. The sea is swimmable from May to November.
Yes. The ghibli (a hot south-westerly wind) can reach 60-70 km/h at Zarzis and raise waves of 2 to 3 metres within a few hours despite an initially calm sea.
