When to go

Best time to visit Tunisia

Tunisia's water year is simple once you stop treating the country as one coastline.

Best overall window

June - October

Warm water on the east and south coasts, with sea temperatures roughly 22°C to 28°C and lighter winds than winter.

Outside that window

Cooler water around 15°C to 18°C, stronger winds often above 17 km/h, and less dependable offshore running.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
