When to go
Tunisia's water year is simple once you stop treating the country as one coastline.
Best overall window
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.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.
