Djerba — Tunisia
A flat, low island in the Gulf of Gabès, off southern Tunisia, joined to the mainland by an ancient causeway and a ferry. Our readings give it 169.6 mm of rain a year over 29 rainy days, with no measurable rain at all in July across the sample years.

Why go
Djerba is sold as a beach week and works perfectly well as one, but the island underneath is stranger and more interesting than the hotel strip suggests. Habitation here never gathered into a single town: it spread across the palm and olive groves as isolated fortified farmhouses, each with its cistern and its own small mosque, which is why you can drive a long way between villages without ever leaving inhabited land. The main town keeps old caravanserais turned into cafés and a Spanish-built fort by the fishing harbour. One of North Africa's oldest synagogues stands in a village a few kilometres inland, and the same village has been covered with commissioned street art.
It suits families, winter-sun travellers who do not need heat, and anyone who will rent something with wheels and go looking. It suits less well people expecting mountains, nightlife or a dense old city: the island is flat, spread out and quiet, and most of its interest is scattered rather than stacked.
Month-by-month climate
This is a dry, sunny island with a sharp summer peak. July reaches 35.1 °C by day with nights at 25.9 °C, August 33.1 °C, and June 30.6 °C. Winter is mild rather than cold: 17.5 °C in January, 18.6 °C in February, 18.7 °C in December, with nights between 10.9 and 12.8 °C, which is pleasant for walking and too cool for the sea.
The rain figures are what set the island apart. The annual total is 169.6 mm over 29 rainy days, a fraction of a European city such as Paris at 655.4 mm over 110 days. December leads the rainfall table and still manages only 31.3 mm over 5 days. June recorded 0.1 mm and July 0 mm across our sample, meaning no measurable rain fell in those months during the years observed, not that rain is impossible.
Spring barely moves here. March at 23.1 °C and April at 23 °C are practically the same month, so the usual reflex of waiting a few more weeks buys you nothing on this island.

When to go
Late April to early June, then October and November. You get 23 to 27 °C in spring and 28.9 °C in October with a sea still warm from summer, plus two to four rainy days a month. July and August are the hot months at 35.1 and 33.1 °C, bearable on the coast but heavy inland and in the souks. Winter stays mild at around 18 °C, good for touring, not for swimming.

What to see in 2, 4 and 7 days
In 2 days
- Walk the main town in the morning: covered market, old caravanserais, and the fort above the fishing harbour.
- Drive inland to the village with the ancient synagogue, then walk its lanes for the commissioned murals.
- Stop at the pottery village in the south-west, where the clay and the workshops are still local.
- End on the north-east beaches, the only stretch with real sand and shallow, warm water.
In 4 days
- Cross the causeway to the mainland for a day, aiming for the underground troglodyte dwellings inland.
- Follow the coastal road round the island: lagoons, salt pans and flamingos on the sandy spits.
- Give a slow morning to the fortified farmhouses scattered in the groves, visible from any minor road.
- Try the island's food properly: brik, grilled fish from the harbour, and the local olive oil.
- Keep an afternoon for a hammam, which is a local habit rather than a tourist attraction here.
In 7 days
- Rent a car or a bicycle for at least half the week; the island is flat and the distances are short.
- Take a two-day trip south to the desert edge, its fortified granaries and a night under canvas.
- Ride out to the ferry crossing at the island's western tip, a working link rather than an excursion.
- Spend a full beach day, but choose the north-east, where the water shelves gently and stays warm.
- Visit a working date and olive holding, the agriculture that shaped the settlement pattern here.
- Set aside one market morning and haggle; prices are elastic and the first number is not the real one.
- Finish near the airport, 21 km from the main town, which makes an early departure straightforward.
Getting there and around
The island's airport (DJE) lies 21 km from the main town and takes seasonal charters as well as scheduled flights; transfers are usually arranged with the hotel, and taxis are metered but often negotiated. The alternatives both sit on the mainland, Sfax (SFA) at 105 km and Monastir (MIR) at 218 km, and both mean crossing by the causeway or the ferry. There is no railway on the island. Getting around means a rental car, a scooter or a bicycle: the terrain is flat, distances are modest and shared long-distance taxis handle mainland trips.

Budget
Country price level compared with France : −79 %
Price index for restaurants and hotels, France = 1000, from European purchasing power parities. It is a country average: it says nothing about one hotel in particular.
Estimates only. Tunisia is among the cheapest destinations in this whole selection, and the island genuinely reflects it outside the large resorts. Rooms of a decent standard start near 40 € and reach about 100 €, less in a small guesthouse in the main town, and considerably more in the all-inclusive hotels on the north-east beaches. Meals in local places run at a few euros, seafood by the harbour more. Car hire and fuel are the items most likely to surprise you, since everything interesting is spread out.
Common mistakes
- Booking the resort strip and never leaving it, then reporting that there is nothing to see on the island.
- Expecting April to be much warmer than March. Our readings put them at 23 and 23.1 °C, almost identical.
- Coming for winter sun and packing for summer. January days reach 17.5 °C, nights fall to 10.9 °C.
- Assuming the island is walkable. Villages sit kilometres apart in the groves, and there is no local rail.
- Treating July as the obvious month. It is the hottest at 35.1 °C by day and 25.9 °C at night.
Frequently asked questions
Does it ever actually rain here?
Rarely, and unevenly. Rainfall amounts to 169.6 mm a year over 29 rainy days, with December the wettest month at 31.3 mm. June and July showed no measurable rain at all during the years observed. When rain does come, it tends to arrive as a short autumn or winter episode rather than as steady weather, so a wet day costs you an afternoon, not a holiday.
Is the island a good base for the Tunisian south?
Yes, and that is its underused advantage. The causeway puts you on the mainland without a boat, and the desert edge, the fortified granaries and the troglodyte villages are all reachable as a long day or an overnight. Plan those as organised trips or with a rental car; the roads are straightforward but the distances inland are real, and afternoon heat in summer makes an early start worthwhile.
